Answer:
The height of the tree is Greater than 50 feet, so Iva’s house is not safe
Step-by-step explanation:
step 1
Find the height of the tree
Let
h ----> the height of the tree
we know that
The tangent of angle of 50 degrees is equal to divide the opposite side to the angle of 50 degrees (height of the tree) by the adjacent side to the angle of 50 degrees (tree’s distance from the house)
so
tan(50°)=h/50
h=(50)tan(50°)=59.6 ft
therefore
The height of the tree is Greater than 50 feet, so Iva’s house is not safe
Answer:
greater than and not safe

6. PATTERNS Complete the pattern: 5, 7,
10, 14,
Answer:
19 is the next number
Step-by-step explanation:
5+2=7
7+3=10
10+4=14
14+5=19
The next number in the pattern is 19.
To complete the number pattern 5, 7, 10, 14, we observe that the differences between the numbers increase by 1. Continuing this pattern, we add 5 to the last number, which results in 19. Thus, the next number in the pattern is 19
To complete the given number pattern: 5, 7, 10, 14, we need to find the rule that governs the pattern. Let's look at the differences between the numbers:
7 - 5 = 210 - 7 = 314 - 10 = 4We can see that the differences are increasing by 1 each time. If this pattern continues, the next difference should be 5. So we add 5 to the last number in the pattern:
14 + 5 = 19
Therefore, the next number in the pattern is 19.
9. Which of the following do you need to know to determine the surface area and volume of a sphere?
A. The radius of the sphere
B. The eccentricity of the sphere
C. The circumference of a great circle on the sphere
D. The radius and eccentricity of the sphere
Answer:
A: radius of the sphere
Step-by-step explanation:
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
to determine the surface area and volume of sphere A: the radius of the sphere is required.
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
How do you find the radius of the sphere?
The radius is half the diameter, so we use the equation r = D / 2. This is the same method used to calculate the radius from the diameter of a circle. If you have a sphere with a diameter of 16 cm, divide 16/2 to find the radius to make it 8 cm. If the diameter is 42, the radius is 21.
A sphere is defined as a set of all points in distant 3D Euclidean space. ("Radius") From a specific point ("center"). Twice the radius is called the diameter, and the pair of points on the sphere on the opposite side of the diameter is called the antipodes.

The equations y= x^2/2 - 8 and y=2x−2 are graphed below. What are the solutions to the equation x^2/2−8=2x−2
graph is attached
Please choose one answer below
x=−6 and x=10
x=−4 and x=4
x=−2 and x=6
x=−8 and x=−2
Your answer is the third option, x = -2 and x=6
We can see this because the solutions of x^2/2 - 8 = 2x - 2 are going to be where the lines y = x^2/2 - 8 and y = 2x - 2, because this is where the two equations are equal to each other.
Therefore, we can just look on the graph at where the two lines intersect, and see that it happens when x = -2 and x = 6.
I hope this helps!
Answer:
x=-2 and x=6
Step-by-step explanation:
The solution to a graph would be where the two lines intersect. When you look at the graph you plot where they connect
(-2, -6), (6, 10)
The x value is the very first variable in an ordered pair. Therefore, the solution to this graph would be x=-2 and x=6.

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 29% each week. The following function represents the weekly weed growth: f(x) = 86(1.29). Rewrite the function to show how quickly the weeds grow each day.
A.f(x) = 86(1.04)*; grows approximately at a rate of 0.4% daily
B.f(x) = 86(1.04)7%, grows approximately at a rate of 4% daily
C.f(x) = 86(1.29)7%; grows approximately at a rate of 20% daily
D.f(x) = 86(1.297); grows approximately at a rate of 2% daily
Answer:
Option A. [tex]f(x)=86[1.04]^{x}[/tex] ; grows approximately at a rate of 0.4% daily
Step-by-step explanation:
we have
[tex]f(x)=86(1.29)^{x}[/tex]
where
f(x) the number of weeds in the garden
x ----> the number of weeks
Calculate how quickly the weeds grow each day
Remember that a week is equal to seven days
so
[tex]f(x)=86(1.29)^{\frac{x}{7}}[/tex]
Using the law of exponents
b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x
so
[tex]f(x)=86[(1.29)^{\frac{1}{7}}]^{x}[/tex]
[tex]f(x)=86[1.04]^{x}[/tex]

One x-intercept for a parabola is at the point
(2,0). Use the quadratic formula to find the
other x-intercept for the parabola defined by
this equation:
y = 4x2 - 4x – 8
Answer:
(2,0) was already given so (-1,0) is the other one.
Step-by-step explanation:
So we are asked to use the quadratic formula.
To find the x-intercepts (if they exist) is use:
[tex]\text{ If } y=ax^2+bx+c \text{ then the } x-\text{intercepts are } (\frac{-b \pm \sqrt{b^2-4ac}}{2a},0)[/tex].
Let's start:
Compare the following equations to determine the values for [tex]a,b, \text{ and }c [/tex]:
[tex]y=ax^2+bx+c[/tex]
[tex]y=4x^2-4x-8[/tex]
So
[tex]a=4[/tex]
[tex]b=-4[/tex]
[tex]c=-8[/tex]
We are now ready to enter into our formula:
[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\frac{4 \pm \sqrt{(-4)^2-4(4)(-8)}}{2(4)}[/tex]
[tex]x=\frac{4 \pm \sqrt{16+16(8)}}{8}[/tex]
[tex]x=\frac{4 \pm \sqrt{16(1+8)}}{8}[/tex]
[tex]x=\frac{4 \pm \sqrt{16}\sqrt{1+8}}{8}[/tex]
[tex]x=\frac{4 \pm 4\sqrt{9}}{8}[/tex]
[tex]x=\frac{ 4 \pm 4(3)}{8}[/tex]
[tex]x=\frac{4 \pm 12}{8}[/tex]
[tex]x=\frac{4(1\pm 3)}{8}[/tex]
[tex]x=\frac{1(1\pm 3)}{2}[/tex]
[tex]x=\frac{1 \pm 3}{2}[/tex]
[tex]x=\frac{1+3}{2} \text{ or } \frac{1-3}{2}[/tex]
[tex]x=\frac{4}{2} \text{ or } \frac{-2}{2}[/tex]
[tex]x=2 \text{ or } -1[/tex]
So the x-intercepts are (2,0) and (-1,0).
(2,0) was already given so (-1,0) is the other one.
Which graph below solves the following system of equations correctly?
y = three over four times x squared minus 3
y = negative three over four times x squared plus 3
A) two quadratic graphs opening up. They intersect at 0 and negative 3.
B)one quadratic graph opening up and one quadratic graph facing down. They intersect at 0, 3.
C) quadratic graph opening up and quadratic graph opening down. They intersect at 0, negative 3.
D) two parabolas one facing down with a vertex at 0, 3 and one facing up with a vertex at 0, negative 3
D) two parabolas one facing down with a vertex at 0, 3 and one facing up with a vertex at 0, negative 3
Step-by-step explanation:First of all, let's rewrite the equations in a mathematical language:
y = three over four times x squared minus 3:[tex]y=\frac{3}{4}x^2-3[/tex]
Since the leading coefficient, the number that accompanies [tex]x^2[/tex] is positive, that is, its value is 3/4, then the parabola opens upward. On the other hand, the vertex can be found as:
[tex](h,k)=\left(-\frac{b}{2a},f\left(-\frac{b}{2a}\right)\right) \\ \\ a=3/4 \\ b=0 \\ c=-3 \\ \\ h=-\frac{0}{2(3/4)}=0 \\ \\ k=f(0)=\frac{3}{4}(0)^2-3=-3 \\ \\ \\ \boxed{Vertex \rightarrow (h,k)=0,-3}[/tex]
y = negative three over four times x squared plus 3:[tex]y=-\frac{3}{4}x^2+3[/tex]
Since the leading coefficient is negative, that is, its value is -3/4, then the parabola opens downward. Similarly the vertex can be found as:
[tex](h,k)=\left(-\frac{b}{2a},f\left(-\frac{b}{2a}\right)\right) \\ \\ a=-3/4 \\ b=0 \\ c=3 \\ \\ h=-\frac{0}{2(-3/4)}=0 \\ \\ k=f(0)=-\frac{3}{4}(0)^2+3=3 \\ \\ \\ \boxed{Vertex \rightarrow (h,k)=0,3}[/tex]
Both graph are shown below and you can see that the conclusion of our problem is correct.

Answer:
D
Step-by-step explanation:
Formula
Volume = pi*r^2*h
Givens
r = x
h = 3x
Volume= 242
Solution
242 = pi * x^2 * 3x
242 = 3.14 * 3x^3 Divide by pi
242/3.14 = 3.14 * 3x^3 / 3.14 Do the division
77 = 3x^3 Divide by 3
77/3 = 3x^3 /3
25.69 = x^3 Take the cube root of both sides.
2.95 = x
The height of the cylinder is 3 times that of the radius of the circle (x)

Find the value of x if A, B, and C are collinear points and B is between A and C.
AB=5x−1,BC=14,AC=25−x
Answer:
x = 2
Step-by-step explanation:
Collinear means that the points A, B and C all lie in a straight line, hence
AB + BC = AC, substitute values
5x - 1 + 14 = 25 - x
5x + 13 = 25 - x ( add x to both sides )
6x + 13 = 25 ( subtract 13 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
The value of x is:
[tex]x=2[/tex]
Step-by-step explanation:Three points are said to be collinear if they lie along a straight line.
Also, it is given that:
Here A, B, and C are collinear points and B is between A and C.
This means that:
[tex]AB+BC=AC-----------(1)[/tex]
Also we are given:
[tex]AB=5x-1,\ BC=14,\ AC=25-x[/tex]
Using property (1) we have:
[tex]5x-1+14=25-x\\\\i.e.\\\\5x+13=25-x[/tex]
Now on adding x on both the side of the equation we have:
[tex]5x+13+x=25\\\\i.e.\\\\5x+x+13=25\\\\i.e.\\\\6x+13=25[/tex]
Now on subtracting 13 on both the sides of the equation we have:
[tex]6x=25-13\\\\i.e.\\\\6x=12\\\\i.e.\\\\x=\dfrac{12}{6}\\\\i.e.\\\\x=2[/tex]

[tex]V=\frac{1}{3}\times \pi \times 96.148[/tex]
[tex]V=\frac{1}{3}\times 3.14 \times 96.148[/tex]
[tex]V=\frac{1}{3}\times 301.904[/tex]
V=100.63 cubic feet
To compute the volume of a cone, one needs to use the formula 1/3πr²h, where 'r' represents the radius of the base and 'h' represents the height of the cone. The specific dimensions of the cone are needed to provide a concrete answer. The given options can't be validated without these details.
Explanation:Without specific parameters such as the radius and height of the cone, we cannot directly calculate the volume of the cone. However, the general formula for finding the volume of a cone is 1/3πr²h, where r represents the radius of the base and h represents the height of the cone. This formula is derived from the geometric principles of a cone's structure. Once the values of r and h are known, they can be substituted into this formula to compute the volume. The answer would then be rounded to the nearest hundredth if necessary. Unfortunately, the choices provided A.32.05 cubic feet, B.38.39 cubic feet, C.56.54 cubic feet, D.100.69 cubic feet aren't helpful without knowledge of the specific cone dimensions.

1) identify info: The cycling tour has 340 bottles of water for each week.there are 10 people on the tour.
2) compile info: 340 bottles for 10 people per week
3) calculate: bottles per person = 340/10 = 34 bottles per person each week
The question asks to figure out how many bottles of water each person on a cycling tour gets per week. By dividing the total bottles of water (340) by the number of people (10), we find that each person receives 34 bottles of water per week.
Explanation:The question is asking us to determine how many bottles of water each person on the cycling tour gets per week. This involves division in mathematics as we are dividing the total number of water bottles by the number of people.
To solve such problems, we start with the total amount given, which is 340 bottles of water here. Then, we divide this total by the number of individuals, which is 10 people in this case. So, the calculation becomes 340 bottles ÷ 10 people.
This calculation gives us 34 bottles. Hence, each person on the cycling tour gets 34 bottles of water per week.

What are the coordinates of the point 3/5 of the way from A(-9,3) to B(21, -2)
Answer: The required co-ordinates of the point are (9, 0).
Step-by-step explanation: We are given to find the co-ordinates of the point that is [tex]\dfrac{3}{5}[/tex] of the way from A(-9,3) to B(21, -2).
Let K be the required point. Then, we mus have
[tex]AK:AB=3:5\\\\\Rightarrow \dfrac{AK}{AK+BK}=\dfrac{3}{5}\\\\\\\Rightarrow 5AK=3AK+3BK\\\\\Rightarrow 2AK=3BK\\\\\Rightarrow AK:BK=3:2.[/tex]
We know that
the co-ordinates of a point that divides the line joining the points (a, b) and (c, d) in the ratio m : n are given by
[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{2}\right).[/tex]
For the given division, m : n = 3 : 2.
Therefore, the co-ordinates of the point K are
[tex]\left(\dfrac{3\times21+2\times(-9)}{3+2},\dfrac{3\times(-2)+2\times3}{3+2}\right)\\\\\\=\left(\dfrac{63-18}{5},\dfrac{-6+6}{5}\right)\\\\=\left(\dfrac{45}{5},\dfrac{0}{5}\right)\\\\=(9,0).[/tex]
Thus, the required co-ordinates of the point are (9, 0).
Building and solving an equation, it is found that the coordinates are: (9,0).
We are given two points: A(-9,3) and B(21, -2).We also want point C(x,y).C is 3/5 of the way from A to B, thus:
[tex]C - A = \frac{3}{5}(B - A)[/tex]
This is used to find both the x-coordinate and the y-coordinate of C.
First, the x-coordinate, considering [tex]C = x, A = -9, B = 21[/tex].
[tex]C - A = \frac{3}{5}(B - A)[/tex]
[tex]x + 9 = \frac{3}{5}(21 + 9)[/tex]
[tex]x = 18 - 9[/tex]
[tex]x = 9[/tex]
Then, the y-coordinate, considering [tex]C = y, A = 3, B = -2[/tex].
[tex]C - A = \frac{3}{5}(B - A)[/tex]
[tex]y - 3 = \frac{3}{5}(-2 - 3)[/tex]
[tex]y = -3 + 3[/tex]
[tex]y = 0[/tex]
Thus, the coordinates are (9,0).

Jason took 40 min to drive from East Mall to West Mall. He drove at an average
speed of 60 km/h for the first 25 min. He then increased his speed by 12 km/h for
the remaining journey. What was the distance between the two malls?
Answer: 28 km
Step-by-step explanation: For the first 25 minutes, he drove 60 km/h. Since there is 60 minutes in an hour, we know that he drove 25 km. The rest of the journey is 15 minutes. 15 minutes is 1/4 of an hour, so get 1/4 of 12 km/h. This would be 3 km. Add 25 km and 3 km. The distance between the 2 malls is 28 km.

the y-intercept means, when the graph of the equation touches or intercepts the y-axis, and when that happens x = 0, or the horizontal distance is at bay.
for the slope on 6), 30 or 30/1 means, for every 1 year(x) passed, the worth(y) increased by 30, or jumped by 30 units, so as the x-axis moved 1, the y-axis moved 30. After 12 years 30 * 12 = 360, and we add the initial 720 and we end up with 1080.
the y-intercept, well, as aforementioned is when x = 0, is year 0.

The solutions of the quadratic equation 0 = (x + 3)(x - 2)
are
0 -6 and 0.
04 and 3.
0-3 and 2
0 -2 and 1.
Answer:
x = -3 or x = 2
Step-by-step explanation:
It is given a quadratic equation,
(x + 3)(x - 2) = 0
To find the solution of given equation
Let (x + 3)(x - 2) 0
⇒ either (x + 3) = 0 or (x - 2) = 0
If (x + 3) = 0 then x = -3
If (x - 2) = 0 then x = 2
Therefore the solution of given equation are
x = -3 or x = 2

If f(x) = 2(X - 5), find f(8).
Answer:
6
Step-by-step explanation:
You can see how f(x) is now f(8), this implies you have to replace any x's you see with an 8.
So f(8) = 2(8-5) = 2(3) = 6

Construct a polynomial function with the following properties: fifth degree, 2 is a zero of multiplicity 3, -2 is the only other zero, leading coefficient is 2.
f(x)=?
Can someone help?
Answer:
[tex]f(x)=2(x-2)^{3}(x+2)^{2}[/tex]
Step-by-step explanation:
we know that
2 is a zero of multiplicity 3 of the polynomial
so
we have that
x=2 is a solution of the polynomial
A factor of the polynomial is
[tex](x-2)^{3}[/tex] ----> is elevated to the cube because is a multiplicity 3
and the other solution is x=-2
since the polynomial is fifth degree, x=-2 must have a multiplicity 2
so
the other factor of the polynomial is
[tex](x+2)^{2}[/tex] ----> is squared because is a multiplicity 2
therefore
The polynomial is equal to multiply the factors by the leading coefficient
so
[tex]f(x)=2(x-2)^{3}(x+2)^{2}[/tex]
The polynomial function based on the given properties: zeros at 2 (with multiplicity 3) and -2 (with multiplicity 1), leading coefficient of 2, is f(x) = 2(x - 2)³(x + 2).
Explanation:To construct a polynomial with given zeros and multiplicities, we need to set up a product of binomial factors based on the zeros, with each binomial factor raised to the power of its respective multiplicity. The resulting polynomial is the given function f(x).
For the given properties, the roots are 2 and -2. The root 2 has multiplicity 3 and the root -2 has multiplicity 1. Also, the leading coefficient is 2. So, we can set up the polynomial function as follows:
f(x) = 2(x - 2)3(x + 2)
This represents a fifth degree polynomial function that has the zeros and multiplicities listed, with the leading coefficient of 2.

Kevin wants to buy an area rug for his living room. He would like the area rug to be no smaller that 48 square feet and no bigger than 80 square feet. If the length is 2 feet more than the width, what are the range of possible values for the width?
Answer:
[tex]6\leq W\leq 8[/tex]
[tex]8\leq L\leq 10[/tex]
Step-by-step explanation:
Let the length of the rug be = L
Let the width of the rug be = W
Area =[tex]L\times W[/tex]
The length is 2 feet more than the width, so [tex]L=W+2[/tex]
Area = [tex](W+2)\times W[/tex]
= [tex]W^{2} +2W[/tex]
Now given is that the area of rug to be no smaller that 48 square feet and no bigger than 80 square feet.
This can be modeled as:
[tex]48\leq W^{2} +2W\leq 80[/tex]
Solving it separately:
[tex]48\leq W^{2} +2W[/tex]
=> [tex]0\leq W^{2}+2W \leq -48[/tex]
=> [tex]6\leq W[/tex]
[tex]W^{2} +2W-80\leq 0[/tex]
=> [tex]W\leq 8[/tex]
We have the following result:
[tex]6\leq W\leq 8[/tex]
And length will be :
[tex]6+2\leq L\leq 8+2[/tex]
[tex]8\leq L\leq 10[/tex]
