Answers

Answer 1

Answer: [tex]143.99\ ft^2[/tex]

Step-by-step explanation:

We need to find the lenght AC and BC of the triangle by applying these identities:

[tex]cos\alpha=\frac{adjacent}{hypotenuse} \\\\sin\alpha=\frac{opposite}{hypotenuse}[/tex]

Then, AC is:

[tex]sin(45\°)=\frac{AC}{24}\\\\AC=24*sin(45\°)\\\\AC=16.97\ ft[/tex]

And BC is:

[tex]cos(45\°)=\frac{BC}{24}\\\\BC=24*cos(45\°)\\\\BC=16.97\ ft[/tex]

The area will be:

[tex]A=\frac{AC*BC}{2}[/tex]

Substituting values, we get:

 [tex]A=\frac{(16.97\ ft)(16.97\ ft)}{2}=143.99\ ft^2[/tex]

What must be a factor of the polynomial function f(x) graft on the coordinate plane below

Answers

Answer:

The correct answer option is B. (x - 1).

Step-by-step explanation:

We are to determine the factor of the polynomial function [tex]f(x)[/tex] which is graphed on the given coordinate plane.

We know that if the zeros (or intercepts) of an equation are [tex] r _ 1 [/tex] and [tex] r _ 2 [/tex] then the factors for this equation will be [tex] ( x - r _ 1 ) [/tex] and [tex]( x - r _ 2 ) [/tex].

From the graph, we can see that it intercepts the x axis at [tex]1[/tex] and [tex]6[/tex]. So the roots will be [tex](x-1)[/tex] and [tex](x-6)[/tex].

Therefore, the correct answer option is B. (x - 1).

Answer: SECOND OPTION.

Step-by-step explanation:

We can verify each option by making eac equal to zero and solving for "x":

First option

[tex]x-3=0\\x=0+3\\x=3[/tex]

The first option is not a factor of the polynomial function, because the parabola does not intersect the x-axis at [tex]x=3[/tex].

Second option

[tex]x-1=0\\x=0+1\\x=1[/tex]

The second option is a factor of the polynomial function, because the parabola intersects the x-axis at [tex]x=1[/tex].

Third option

[tex]x+1=0\\x=0-1\\x=-1[/tex]

The third option is not a factor of the polynomial function, because the parabola does not intersect the x-axis at [tex]x=-1[/tex].

Fourth option

[tex]x+3=0\\x=0-3\\x=-3[/tex]

The fourth option is not a factor of the polynomial function, because the parabola does not intersect the x-axis at [tex]x=-3[/tex].

Solve the equation by completing the square. Round to the nearest hundredth if necessary. 4x2 + 8x – 32 = 0

Answers

[tex]4x^2 + 8x - 32 = 0\\x^2+2x-8=0\\x^2+2x+1-9=0\\(x+1)^2=9\\x+1=3 \vee x+1=-3\\x=2 \vee x=-4[/tex]

For this case we must solve the following expression by completing squares:

[tex]4x ^ 2 + 8x-32 = 0[/tex]

We divide between 4 on both sides of the equation:

[tex]x ^ 2 + 2x-8 = 0[/tex]

We add 8 to both sides of the equation:

[tex]x ^ 2 + 2x = 8[/tex]

We divide the middle term between 2 and square, this we add to both sides of the equation:

[tex]x ^ 2 + 2x + (\frac {2} {2}) ^ 2 = 8 + (\frac {2} {2}) ^ 2\\x ^ 2 + 2x + 1 ^ 2 = 8 + 1\\x ^ 2 + 2x + 1 ^ 2 = 9\\(x + 1) ^ 2 = 9[/tex]

We apply root to both sides:

[tex]x + 1 =\pm \sqrt {9}[/tex]

We have two roots:

[tex]x_ {1} = \sqrt {9} -1 = 3-1 = 2\\x_ {2} = - \sqrt {9} -1 = -3-1 = -4[/tex]

Answer:

[tex]x_ {1} = 2\\x_ {2} = - 4[/tex]

Help, what is the measure of arc QS

Answers

Answer:

168°

Step-by-step explanation:

∠QRS is an angle formed by 2 chords of the circle and is half the measure of its intercepted arc QS, that is

m QS = 2 × 84° = 168°

Applying the inscribed angle theorem, the measure of arc QS is: 168°.

What is the Inscribed Angle Theorem?

According to the inscribed angle theorem, the measure of an inscribed angle in a circle equals half of the measure of the intercepted arc.

Based on the inscribed angle theorem,

arc QS = 2(m∠QRS)

arc QS = 2(84)

arc QS = 168°

Therefore, applying the inscribed angle theorem, the measure of arc QS is: 168°.

Why do you think the acceleration due to gravity is represented by a negative number?

Answers

Answer:

Step-by-step explanation:

Acceleration due to gravity is the rate at which an object changes its velocity due to the force of gravity.On Earth, the average acceleration due to gravity is -9.81 m/s².The acceleration due to gravity is ALWAYS negative.  Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s², regardless of the direction.

The acceleration is negative when going up because the speed is decreasing.  The acceleration is negative when going down because it is moving in the negative direction, down.  Even at the top of the path where the instantaneous speed is 0 m/s, the acceleration is still -9.81 m/s². ...

Find the slope of DE and FG

Answers

slope of DE would be [tex]\( m_{DE} = \frac{(2c - b)}{(0 - (-a))} = \frac{(2c - b)}{a} \).[/tex]

slope of FG would be[tex]\( m_{FG} = \frac{(0 - c)}{(0 - (a+b))} = \frac{-c}{-(a+b)} = \frac{c}{a+b} \).[/tex]

To find the slope of line segments DE and FG from a trapezoid on a coordinate plane, we can follow these steps:

1. Identify the Coordinates of Endpoints:

  - For DE, identify coordinates D and E.

  - For FG, identify coordinates F and G.

2. Use the Slope Formula:

  - The slope  m  of a line passing through two points [tex]\( (x_1, y_1) \) and \( (x_2, y_2) \) is given by \( m = \frac{(y_2 - y_1)}{(x_2 - x_1)} \).[/tex]

3. Calculate the Slope for DE:

  - Plug the coordinates of D and E into the slope formula.

4. Calculate the Slope for FG:

  - Plug the coordinates of F and G into the slope formula.

Given the coordinates in the image, let's calculate the slopes for DE and FG:

For DE:

- Let's say D has coordinates  (-a, b)  and E has coordinates (0, 2c)

- The slope of DE would be [tex]\( m_{DE} = \frac{(2c - b)}{(0 - (-a))} = \frac{(2c - b)}{a} \).[/tex]

For FG:

- Let's say F has coordinates[tex]\( (a+b, c) \)[/tex] and G has coordinates  (0, 0) .

- The slope of FG would be[tex]\( m_{FG} = \frac{(0 - c)}{(0 - (a+b))} = \frac{-c}{-(a+b)} = \frac{c}{a+b} \).[/tex]

Which of the following is the equation of a line that passes through (-2,1) and (-4,-3)?

Answers

Answer:

The equation is y= 2x+5

Step-by-step explanation:

Lets find the slope of the line through the points (-2,1) and (-4,-3).

where x1 = -2,  y1= 1,  x2= -4,  y2 = -3.

Now apply slope formula:

m= y2-y1/ x2-x1

m= -3-1/-4-(-2)

m = -4/-4+2

m= -4/-2

Divide the term by 2:

m = 2

Now we will apply point slope formula:

y-y1 = m (x-x1)

Now substitute the values in the formula:

y-1=2(x-(-2))

y-1 =2(x+2)

y-1=2x+4

Now combine the constants:

y= 2x+4+1

y=2x+5

So the equation is y= 2x+5 ....

A rectangular prism has a volume of 300 ft. If the base measures 5 ft by 8 ft, what is the height of the prism?
40 ft
13 ft
23.1 ft
7.5 ft

Answers

Answer:

7.5 ft

Step-by-step explanation:

Volume of a prism is V = L*W*H.

In this case, the volume is V = 300 ft^3 (not 300 ft).  Therefore,

300 ft^3 = L*W*H = (8 ft)(5 ft)(height)

Solving for the height, H, we get:

       300 ft^3

H = --------------- = 7.5 ft

         40 ft^2

Answer:

7.5 ft

Step-by-step explanation:

Vole is the length time the width times the height

V = l*w*h

Substituting what we know

300 = 5*8*h

300 = 40h

Divide each side by 40

300/40 =40h/40

7.5 =h

Products of both

To do this, we have to apply the laws of indices,

Follow the highlighted steps

Step 1: Multiply both parameters directly

Since they both have the same roots, they can be multiplied directly according to the law of indices

[tex]\sqrt[3]{16x^{7} } * \sqrt[3]{12x^{9} }[/tex] becomes

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex]

Step 2: Apply the 1st law of indices

First law of indices states that

[tex]x^{a} * x^{b} = x^{a + b}[/tex]

So, [tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] becomes

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{7} * x^{9} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{7+9} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{16} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{192 * x^{16} }[/tex]

Step 3: Rewrite the expression

[tex]\sqrt[3]{192 * x^{16} }[/tex] = [tex]({192 * x^{16} })^{\frac{1}{3} }[/tex]

Step 4: Expand the Expression in bracket

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]({64 * 3* x^{15} * x^{1} })^{\frac{1}{3} }[/tex]

Break down into bits

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]64^\frac{1}{3} * 3^\frac{1}{3} * (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex](4^{3}) ^\frac{1}{3} * 3^\frac{1}{3} * (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex](4^{3*\frac{1}{3}}) * 3^\frac{1}{3} * (x^{15}*^\frac{1}{3}) * (x^{\frac{1}{3}})[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4 * 3^\frac{1}{3} * (x^{5}}) * (x^{\frac{1}{3}})[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4 (x^{5}})* 3^\frac{1}{3} * (x^{\frac{1}{3}})[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4x^{5}} * (3^\frac{1}{3} * x^{\frac{1}{3}})[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4x^{5}} * (3x)^\frac{1}{3}[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4x^{5}} * \sqrt[3]{3x}[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]4x^{5}} (\sqrt[3]{3x})[/tex]

What is triangle and its properties?

In the  Geometry, the triangle is a 3-sided polygon that consists of 3 edges and 3 vertices. The most important property of the triangle is that the sum of the internal angles of the triangle is = to 180 degrees. its property is known as angle sum property of triangle.

We have been given the image of the right triangle and we are asked to find the value of the tan(60) for our given triangle

from we know that tangent represents the relation between opposite or adjacent of the right triangle.

[tex]tan = \frac{opposite}{adjacent}[/tex]

We can see that our adjacent side is not given, but corresponding angle to adjacent side is given that is 30 degrees. So we could conclude that our given triangle is 30-60-90 triangle.

from the sides corresponding to 30-60-90 triangle equals to[tex]x,x\sqrt{3}[/tex] and [tex]2x[/tex] , so the adjacent side for our given triangle will be,

[tex]x\sqrt{3} =8 \sqrt{3\\\\\\[/tex]

[tex]\frac{x \sqrt{3} }{\sqrt{3} } =\frac{8\sqrt{3} }{\sqrt{3} }[/tex]

Upon substituting these values on above formula we will get,

[tex]tan( 60^{0} ) = \frac{8\sqrt{3} }{8} \\tan( 60^{0})=\sqrt{3}[/tex]

hence, the value of tan(60) is  [tex]\sqrt{3}[/tex]and option B is the correct choice.

What is the exact distance from (−1, 4) to (6, −2)?

Answers

Answer:

The exact distance is √(29) or 29^(1/2)

Step-by-step explanation:

Find the answer using the distance formula (aka the Pythagorean theorem)

d=√(x1+x2)^2+(y1+y2)^2)

d=√(-1+6)^2+(4+-2)^2), Solve for d:

d= √((25)+(4))

d=√(29)

Answer:

[tex]\sqrt{35}[/tex]

Step-by-step explanation:

To calculate the distance (d) use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)

d = [tex]\sqrt{(6+1)^2+(-2-4)^2}[/tex]

  = [tex]\sqrt{7^2+(-6)^2}[/tex]

  = [tex]\sqrt{49+36}[/tex] = [tex]\sqrt{85}[/tex] ← exact value

HELP!!Use the figure to decide the type of angle pair that describe <6 and<4.

Answers

Angle 6, an acute angle, measures below 90 degrees, reflecting a sharp inclination. Angle 4, a right angle at precisely 90 degrees.

In the geometric configuration, Angle 6 is characterized as an acute angle, signifying that its measure falls between 0 and 90 degrees. Acute angles are typically associated with sharp inclinations, emphasizing a compact angular span. On the other hand, Angle 4 is identified as a right angle, precisely measuring 90 degrees.

Right angles are distinctive for their perpendicular alignment, forming the cornerstone of rectangular shapes and providing structural stability. The significance of Angle 4 lies in its pivotal role in defining perpendicularity within geometric constructs.

This geometric interplay showcases the diversity of angles, with acute angles like Angle 6 emphasizing sharpness and right angles like Angle 4 embodying orthogonality, contributing to the intricacies and precision inherent in geometric relationships.

A class consists of 55% boys and 45% girls. It is observed that 25% of the class are boys and scored an A on the test, and 35% of the class are girls and scored an A on the test. If a student is chosen at random and is found to be a girl, the probability that the student scored an A is .

Answers

Answer:

The probability that the student scored an A is : 0.778

Step-by-step explanation:

There are 55% boys and 45% girls

So, No of boys is: 55/100

No of girls is: 45/100

So, total no of girls are: 45

Since 35% of the girls scored A on test

No of girls who scored A on test = 35

The probability that the student scored an A is: 35/45

The probability that the student scored an A is : 0.778

Answer:

[tex]P(A | B)=\frac{7}{9}=0.778[/tex]

Step-by-step explanation:

Let's call B the event that consists of the selected student being a girl

Call A to the event in which the selected student obtained an A.

Then we look for the probability that A will occur given that B. That is, we look for P(A | B)

This is a conditional probability and is calculated using the following formula

[tex]P(A | B)=\frac{P(A\ and\ B)}{P(B)}[/tex]

In this case

[tex]P(B)=0.45\\P(A\ and\ B)=0.35[/tex]

So

[tex]P(A | B)=\frac{0.35}{0.45}[/tex]

[tex]P(A | B)=\frac{7}{9}=0.778[/tex]

What is the position of F on the number line below? write your answer as a fraction or mixed number​

Answers

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

There are 4 steps to complete to go from 0 to 1. Hence each step is:

1 out of 4, or simply  [tex]\frac{1}{4}[/tex]

F is located at the 3rd mark, which will be  [tex]\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}[/tex]

Hence, F is located at  [tex]\frac{3}{4}[/tex]

Answer:

F is on [tex]\frac{3}{4}[/tex] on the number line

Step-by-step explanation:

Notice in the image that between 0 and 1 there are 4 subdivisions.

Then divide.

[tex]\frac{1}{4} = 0.25[/tex].

Each subdivision is equal to 0.25 units.

Point F is in the third subdivision.

This means that the distance between 0 and F is:

[tex]\frac{1}{4}*3 = \frac{3}{4} = 0.75[/tex].

Finally F is on [tex]\frac{3}{4}[/tex] on the number line

what is the average rate of change from x=-4 to x=1​

Answers

The rate of change is negative one
When you look at the two points and draw a line, you can see that it has a slope of -1 which is the average rate of change for it

Answer:

- 1

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 4, 1 ]

From the graph

f(b) = f(1) = - 1

f(a) = f(- 4) = 4

average rate of change = [tex]\frac{-1-4}{1-(-4)}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1
