Answer:
[tex]0.035\times 10^{3}[/tex]
Step-by-step explanation:
Given: The value of 0.035
Now, as we know 0.035 has three decimal place which mean if we multiply by 1000 then we have the product 35 which is greater than 1 and less than 100, however if we multiply 0.035 by 10000 then the output will be greater than 100, which is invalid.
Lets us use hit and trail method.
[tex]0.035\times 1000 = 35 < 100\\\\0.035\times 10000= 350 >100[/tex]
Now lets put the value in expression
[tex]0.035\times 10^{3}[/tex]

what is the x intercept od this piecewise function? A) (0,2) B) (2,0) C) (0,4) D) (4,0)
Answer: Choice B) (2,0)
======================================
Set the first piece equal to zero and solve for x
x^2 - 4 = 0
x^2 = 4
x = sqrt(4) or x = -sqrt(4)
x = 2 or x = -2
Keep in mind that the first piece y = x^2-4 is only graphed when x = 2 or larger, so we ignore x = -2. This is one x intercept, but there may be more. Let's check the other graph to see what we get.
----------
Set the second piece equal to zero and solve for x
x-2 = 0
x-2+2 = 0+2
x = 2
We get the same result as above in the prior section. Because of this, the two pieces connect at this junction point.
The x intercept x = 2 leads to the location (2,0). The x intercept always occurs when y = 0.
The graph below shows this.
side note: the red piece y = x^2 - 4 looks linear, but it's actually not a straight line. It's just a really stretched out curve.

Please Help ASAP!! Domain and range of function...
Answer:
Domain: All Real Numbers
Range: All Integers
Step-by-step explanation:
Integers are numbers positive and negative and 0 but cannot be partial numbers. Partial numbers are decimal or fractional numbers when most simplified.
Real numbers are positive and negative and 0 and can be partials, decimal numbers, fractions, radicals, anything considered a number.
The domain is all real numbers. Since the graph has lines that show between the grid lines, decimal numbers are included.
The range is all integers because there are only number on the grid lines. Real numbers would include all of the decimal numbers that not in the white spaces.
Answer:
the bottom right
Step-by-step explanation:
range cannot be all real numbers because they have to be integers(for example, 3/4 is a real number but it is not an integer)as the lines are on integer numbers. But the domain can be all real numbers because the lines go through all real numbers
Given a square pyramid with a height of 21 feet and a volume of 3969 cubic feet, find the length of one side of the square base.
Answer:
The length of one side of the square base is 24 feet.
Step-by-step explanation:
Given:
Volume of square pyramid(V) = 3969 cubic feet, and its height(h) = 21 feet.
Now, we need to find the length of one side(a) of the square base.
So. by putting the formula of square pyramid we get our length of one side(a):
[tex]V=a^{2}\frac{h}{3}[/tex]
[tex]3969=a^{2}\times \frac{21}{3}[/tex]
[tex]3969= a^{2}\times 7[/tex]
Dividing both sides by 7 we get:
[tex]567=a^{2}[/tex]
Using square root both sides we get:
[tex]23.81=a[/tex]
a = 24 feet (approximately).
Therefore, the length of one side of the square base is 24 feet.
The length of one side of the square base of the pyramid is approximately 23.8 feet. This was determined using the volume formula for a square pyramid and solving for the side length. The base area and height were key in finding this solution.
To find the length of one side of the square base of the pyramid, we can use the formula for the volume of a square pyramid:
Volume = (1/3) × Base Area × Height
Given:
Volume = 3969 cubic feetHeight = 21 feetLet the side length of the square base be s feet. The base area of the square is s².
Using the volume formula, we get:
3969 = (1/3) × s² × 21
First, solve for s²:
3969 = 7 × s²
s² = 3969 / 7
s² = 567
Now, take the square root of both sides to find s:
s = √567 ≈ 23.8 feet
Therefore, the length of one side of the square base of the pyramid is approximately 23.8 feet.
Sandra wrote p(x) = 30x + 5x2 in vertex form. Her work is below.
1. p(x) = 5x2 + 30x
2. p(x) = 5(x2 + 6x)
3. (six-halves) squared = 9;
4. p(x) = 5(x2 + 6x + 9) – 5(9)
5. p(x) = 5(x + 3)2 – 45
Describe Sandra’s function.
Answer:
p(x) = 5(x + 3)² - 45
Step-by-step explanation:
Sandra wrote the function as p(x) = 30x + 5x².
So, this is a formula of a parabola, and this we have to convert into vertex form.
Now, rearranging the function we get
p(x) = 5(x² + 6x)
⇒ p(x) = 5(x² + 6x + 9) - 45
⇒ p(x) = 5(x + 3)² - 45
So, this is the vertex form and the vertex of the parabola is (-3,-45).
We know the formula of a parabola having vertex at (m,n) and axis parallel to positive y-axis is given by
(x - m)² = 4a(y - n)
⇒ [tex]y = \frac{1}{4a} (x - m)^{2} + n[/tex] (Answer)

Two factory plants are making TV panels. Yesterday, Plant A produced 16,000 panels. Five percent of the panels from Plant A and 2% of the panels from Plant B
were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 4%?
Number of panels produced by Plant B????
Answer:
Number of panels produced by Plant B is 8,000.
Step-by-step explanation:
The number of panels produced by Plant A = 16,000
The number of defective panels from A = 5%
Now, 5% of 16,000 = [tex]\frac{5}{100} \times 16,000 = 800[/tex]
So, out of 16,000 panels produced by pant A , 800 are defective. .. (1)
Let us assume number of panels produced by Plant B = m
The number of defective panels from B = 2%
Now, 2% of m = [tex]\frac{2}{100} \times m = 0.02 m[/tex]
So, out of total m panels produced by pant B , 0.02 m are defective. .. (2)
Now, total panels produced over all = Panels by A + Panels by B
= 16,000 + m
The percentage of defected panels over all = 4%
Now, 4% of (16,000 + m) = [tex]\frac{4}{100} \times (16,000+m) = (0.04)(16,000 + m)[/tex]
Also, the total number of defective panels = Defective from A + Defective from B
⇒(0.04)(16,000 + m) = 800 + 0.02 m from (1) and (2)
or, 640 + 0.04 m = 800 + 0.02
or, 0.02 m = 160
⇒ m = 160 /0.02 = 8,000
or, m = 8,000
Hence, Number of panels produced by Plant B is 8,000.
The number of panels produced by Plant B can be calculated by setting up an equation representing the total number of defective panels from both plants. Solving this equation yields a result of 20,000 panels for Plant B.
Explanation:Let's denote the number of panels produced by Plant B as X. According to the problem, 5% of the panels produced by Plant A were defective, which is 0.05*16,000 = 800. Since 2% of the panels produced by Plant B were defective, that's 0.02*X panels.
The total number of defective panels from both plants was 4% of the total production, which means it was equivalent to 0.04 * (16,000+X). Setting this equation equal to the sum of defective panels from both plants, we get the equation 0.04*(16,000+X) = 800 + 0.02*X.
Solving the above equation, we get X = 20,000. Therefore, "Plant B produced 20,000 panels".

A box of seeds contains p packets. Each packet contains s seeds. Which equation can be used to find the number of seeds in a box (b)?
(A) p= sb
(B) p= s/b
(C) b= ps
(D) b= p/s
The total number of seeds in the box is found by multiplying the number of packets by the number of seeds per packet, yielding the equation b = ps.
Explanation:The equation we are looking for will help us find the total number of seeds in a box, which we will call b. Since the box has p packets and each packet contains s seeds, we can find the total number of seeds by multiplying the number of packets by the number of seeds in each packet. Therefore, the correct equation to represent this relationship is b = ps, which means the total number of seeds in the box (b) is the product of the number of packets (p) and the number of seeds per packet (s).

5 million, four thousand, three hundered in standard form
5 million, four thousand, three hundered in standard form is [tex]5.0043 \times 10^{6}[/tex]
Solution:Need to represent 5 million, four thousand, three hundered in standard form
5 million = 5000000
4 thousand = 4000
3 hundred = 300
5 million, four thousand, three hundred = 5000000 + 4000 + 300 = 5004300
In standard form, decimal comes after first digit and multiply to power of 10 dependency on total digits of number.
In our case, given number is 5004300.
So we need decimal after first and after that multiplying it by appropriate power of 10. So,
[tex]5004300=5.0043 \times 10^{6}[/tex]
Hence [tex]5.0043 \times 10^{6}[/tex] is standard form of 5004300 that is standard form of 5 million, four thousand, three hundred.
The number '5 million, four thousand, three hundred' is written in standard form as 5,004,300. Standard form notation uses commas to split up large numbers into thousands, millions, etc.
Explanation:The standard form notation for representing numbers is a helpful way to write large or very small numbers in a more compact format. In this case, the number '5 million, four thousand, three hundred' in standard form would be represented as 5,004,300. This combines all the components: millions, thousands, and hundreds into one concise figure.
In standard form, this value is written by placing commas every three digits, starting from the right. So, '5 million' is written as 5,000,000. 'Four thousand' is written as 4,000 and 'three hundred' as 300. When you add these values together, you get 5,004,300.

A rectangular picture has a height that is 5/7 of its width. It’s area is 140 square inches. What are the dimensions of the picture?
The width of the picture is 14 inches and the height is 10 inches, resulting in dimensions of 14 inches by 10 inches.
Explanation:This problem can be solved by using the formula for the area of a rectangle, which is area = length x width. We are given that the area is 140 square inches, and that the height of the picture is 5/7 of its width. Therefore, we can create the equation 140 = width x (5/7)width.
By simplifying this equation, we can then solve for the width:
Multiply both sides of the equation by 7/5: [tex]width^2[/tex] = 140 x (7/5)Simplify the equation: [tex]width^2[/tex] = 196Take the square root of both sides: width = sqrt(196) = 14 inchesSo the width of the picture is 14 inches. To find the height, we multiply the width by 5/7: height = 14 x (5/7) = 10 inches.
Therefore, the dimensions of the picture are 14 inches by 10 inches.

A ball is thrown vertically upward from the ground with an initial velocity of 109 ft/sec. Use the quadratic function
h(t) = -16t2 + 109t to find how long it will take for the ball to reach its maximum height, and then find the maximum
height. Round your answers to the nearest tenth.
Answer:
Time taken by the ball to reach its maximum height is 3.4 sec
maximum height reached by the ball is 185.6ft
Step-by-step explanation:
h(t) = -16[tex]t^{2}[/tex] + 109t
height is maximum ⇔ [tex]\frac{d}{dt}[/tex](h) = 0 and [tex]\frac{d^{2} }{dt^{2} }[/tex](h) < 0
[tex]\frac{d}{dt}[/tex](h) = 0 ⇒ -32t + 109 = 0
⇒t = [tex]\frac{109}{32}[/tex] ⇒ t = 3.4sec
[tex]\frac{d^{2} }{dt^{2} }[/tex](h) = -32 < 0
∴h(t) is maximum at t = 3.4
and maximum height is h(3.4) = -16×[tex]3.4^{2}[/tex] + 109×3.4 ⇒ h = 185.6ft
Answer:
The maximum height with rounding by the nearest tenth is [tex]280.56\ m[/tex]
Explanation:
Initial velocity of ball [tex]=109\ ft/sec[/tex]
Quadratic function [tex]$h(t)=-16t x^{2} +109t$[/tex]
Maximum height[tex]=?[/tex]
Step 1:
This ball has its height related to time by a parabola with the equation:
[tex]$s=\frac{1}{2} \times a \times t^{2}+v_{0} \times t+s_{0}$[/tex]
where [tex]$s$[/tex] is the height so is the starting height, [tex]v_{0}[/tex] is its starting velocity [tex]$=109 \ {ft} / \mathrm{s}$[/tex]
[tex]$a$[/tex] is the acceleration of gravity, which is [tex]$-16 \ {ft} / \mathrm{s}$[/tex] every second.
Step 2:
Time required to reach its maximum height:
[tex]$v=a^{*} t+v_{0}[/tex] (its velocity is the acceleration of gravity × time [tex]+ v_0[/tex]) [tex]$v$[/tex] will slow down from [tex]$109 \ {ft} / \ s[/tex] to [tex]$0 \mathrm{ft} / \mathrm{s}$[/tex]
And it slowing down at [tex]$16 \mathrm{ft} / \mathrm{s}$[/tex] :
[tex]t(s)=0,1,2,3,4,5,6[/tex]
[tex]V (m/s)=109,93,77,61,45,29,13[/tex]
Before [tex]$7 \mathrm{~s}$[/tex], it will hit the ground.
Exact calculation [tex]$t=\frac{109 f t / s}{16 f t / s}=6.81 s$[/tex]
Thus we can say at the height of,
[tex]$\mathrm{t}_{\max }=\frac{6.81}{2} \\=3.4\ sec[/tex]
Step 3:
Plug the [tex]t_m_a_x[/tex] sec value back into equation:
[tex]$h(t)=t \cdot(-16 t+109)$[/tex]
[tex]$h_{\max }=3.4 \cdot(-16.4 .1875+109)$[/tex]
[tex]$h_{\max }= 185.6\ m[/tex]

A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour. The same recipe calls for 1/4 cup of coconut for every 3/4 cup of chopped apple. To yield a batch of 30 muffins, how much flour will be needed in the mix?
Answer:
[tex]4\dfrac{3}{8}[/tex] cups of flour
Step-by-step explanation:
A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour.
Then this recipe, which yields one muffin, calls for
[tex]\dfrac{2}{3}:12=\dfrac{2}{3}\cdot \dfrac{1}{12}=\dfrac{1}{18}[/tex]
cup of milk for every
[tex]1\dfrac{3}{4}:12=\dfrac{7}{4}\cdot \dfrac{1}{12}=\dfrac{7}{48}[/tex]
cups of flour.
Thus,
this recipe, which yields a batch of 30 muffins, calls for
[tex]\dfrac{1}{18}\cdot 30=\dfrac{5}{3}=1\dfrac{2}{3}[/tex]
cups of milk for every
[tex]\dfrac{7}{48}\cdot 30=\dfrac{210}{48}=\dfrac{35}{8}=4\dfrac{3}{8}[/tex]
cups of flour.
Final answer:
To calculate the amount of flour needed to yield 30 muffins, we first find the amount of flour required for a single muffin and then scale it up to 30 by multiplying. For 30 muffins, approximately 1.094 cups of flour are required based on the original recipe ratios.
Explanation:
The question involves the use of ratios to calculate the amount of a particular ingredient required for a different quantity of the final product. Since the original recipe yields 12 muffins with 1 3/4 cups of flour, we first need to determine how much flour is needed for one muffin by dividing 1 3/4 cups by 12. After finding the flour quantity per muffin, we then multiply that by 30 to find out how much flour is needed for 30 muffins.
Step 1: Calculate the amount of flour for one muffin.
Amount of flour per muffin: 1 3/4 cups / 12 =
7/4 cups / 12 = 7/48 cups per muffin.
Step 2: Calculate the amount of flour needed for 30 muffins.
Amount of flour for 30 muffins: 7/48 cups per muffin x 30 = 7/48 x 30 =
52.5/48 or approximately 1.094 cups of flour.

the three median of a triangle intersect as a point. which measurements could represent the segments of one of the medians? 2 and 3 , 3 and 4.5 , 3 and 6 , 3 and 9
In a triangle, the point where the medians intersect, known as the centroid, divides each median into two segments in a 2:1 ratio. In this context, only the measurement of segments 3 and 6 fit this property.
Explanation:The median of a triangle is a segment joining a vertex to the midpoint of the opposite side. In this question, we are considering segments of a median, so we're considering the vertex of the triangle to the centroid (where medians intersect) and from the centroid to the midpoint of the opposite side.
The key property of medians in a triangle is that the centroid, or point of intersection, divides each median into two segments in the ratio 2:1. This means the distance from a vertex to the centroid is twice the distance from the centroid to the midpoint of the opposite side.
From the provided segments, only 3 and 6 fit this principle. This means the distance from the vertex to the centroid is 3 (representing two-thirds of the median) and the distance from the centroid to the midpoint of the opposite side is 6 (representing one-third of the median).
