Step-by-step explanation:
what is the volume of the rectangle pyramid show below?
Answer:
Option (3)
Step-by-step explanation:
Volume of a rectangle = [tex]\frac{1}{3}(\text{Area of the rectangular base)(\text{Height})}[/tex]
Area of the rectangular base = Length × Width
= 7 × 8
= 56 square in.
Height of the pyramid = 9 in.
Therefore, Volume of the given pyramid = [tex]\frac{1}{3}(56)(9)[/tex]
= 168 cubic in.
Option (3) will be the correct option.

Both diagonal lengths of a kite are multiplied by 3. Which of the following describes the effect of this change on the area? PLZZ HELP!!! THE RED IS THE ONE I GOT WRONG
Answer:
The area is multiplied by 9
Step-by-step explanation:
Since the area of a kite is the two diagonals multiplied together and then divided by two (turn the kite into two triangles if you don't believe me), then the change in area would be from x*y/2 to 3x*3y/2, which is the same as 9x*y/2, i.e. nine times the original area.
Answer:
The correct answer: The area is multiplied by 9.

A cannon ball has been catapulted through the air and follows the path created by the
function f(t) = -16t2 + 30t + 7 where f(t) is the height of the cannon ball in
meters at any given time (t) in seconds.
Answer:
the cannon ball's maximum height is 21 meters rounded to the nearest whole number
Step-by-step explanation:
The maximum height of the cannonball will be 21.06 meters when the time t = 0.9375 seconds.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
A cannonball has been catapulted through the air and follows the path created by the function given below.
f(t) = -16t² + 30t + 7
where f(t) is the height of the cannonball in meters at any given time (t) in seconds.
Then the height of the cannonball will be given by the differentiation. Then we have
[tex]\rm \dfrac{d}{dx} f(t) = -16t^2 + 30 t + 7 \\\\\\\dfrac{d}{dx} f(t) = -32t + 30[/tex]
Then again differentiate to check whether the value is maximum or minimum.
[tex]\rm \dfrac{d^2}{dx^2} f(t) = -32t + 30\\\\\\\dfrac{d^2}{dx^2} f(t) = -32\\\\\\\dfrac{d^2}{dx^2} f(t) < 0[/tex]
Then the value of the height will be maximum for f'(t) = 0.
f'(t) = 0
-32t + 30 = 0
t = 30/32
t = 0.9375
Then the maximum height will be
f(t) = -16(0.9375)² + 30(0.9375) + 7
f(t) = -14.0625 + 28.125 + 7
f(t) = 21.0625
f(t) = 21.06 meters

What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

istep by istep explanasion:A basketball player makes a free throw 82.6% of the time. The player attempts 5 free throws. Use a histogram of the binomial distribution to determine what is the most likely outcome.
Answer:
The most likely outcome is exactly 4 free throws
Step-by-step explanation:
Given
[tex]n = 5[/tex] --- attempts
[tex]p = 82.6\%[/tex] ---- probability of a successful free throw
[tex]p = 0.826[/tex]
Required
A histogram to show the most likely outcome
From the question, we understand that the distribution is binomial.
This is represented as:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
For x = 0 to 5, where x represents the number of free throws; we have:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (1 - 0.826)^{5-0}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (0.174)^{5}[/tex]
[tex]P(X = 0) = 1 * 1 * 0.000159 \approx 0.0002[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (1 - 0.826)^{5-1}[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (0.174)^4[/tex]
[tex]P(X = 1) = 5 * 0.826 * 0.000917 \approx 0.0038[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (1 - 0.826)^{5-2}[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (0.174)^{3}[/tex]
[tex]P(X = 2) = 10 * 0.682 * 0.005268 \approx 0.0359[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (1 - 0.826)^{5-3}[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (0.174)^2[/tex]
[tex]P(X = 3) = 10 * 0.5636 * 0.030276 \approx 0.1706[/tex]
[tex]P(X = 4) = ^5C_4 * 0.826^4 * (1 - 0.826)^{5-4}[/tex]
[tex]P(X = 4) = 5 * 0.826^4 * (0.174)^1[/tex]
[tex]P(X = 4) = 5 * 0.4655 * 0.174 \approx 0.4050[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (1 - 0.826)^{5-5}\\[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (0.174)^0[/tex]
[tex]P(X = 5) = 1 * 0.3845 * 1 \approx 0.3845[/tex]
From the above computations, we have:
[tex]P(X = 0) \approx 0.0002[/tex]
[tex]P(X = 1) \approx 0.0038[/tex]
[tex]P(X = 2) \approx 0.0359[/tex]
[tex]P(X = 3) \approx 0.1706[/tex]
[tex]P(X = 4) \approx 0.4050[/tex]
[tex]P(X = 5) \approx 0.3845[/tex]
See attachment for histogram
From the histogram, we can see that the most likely outcome is at: x = 4

At school, 588 students bought a school
shirt, and 147 students did not. What
percent of the students bought a school
shirt?
Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.

Your friend tosses a ball into the air at an initial velocity of 18 feet per second. The equation h = -8t^2 + 18t + 5 models the height h of the ball t seconds after it was thrown.
1. How long was the ball in the air?
2. How high did the ball get?
3. When did the ball hit its highest point?
Answer:
2.5 s15.125 ft1.125 sStep-by-step explanation:
The time and height of the highest point represent the vertex of the graph of the height equation. The positive zero of the equation represents the time the ball was no longer in the air.
__
These points are conveniently found from the vertex form of the equation.
h = -8(t² -9/4t) +5
h = -8(t² -9/4t +81/64) +5 +8(81/64)
h = -8(t -9/8)² +15 1/8 . . . . . . . . vertex is (9/8, 15 1/8)
__
Solving for the zeros, we find ...
0 = -8(t -9/8)² +15 1/8
121/64 = (t -9/8)² . . . . . . subtract 15 1/8, divide by -8
11/8 = t -9/8 . . . . . . . take the positive square root
t = 20/8 = 2.5 . . . . the time the ball hits the ground
__
1. The ball was in the air for 2.5 seconds
2. The ball got to a height of 15 1/8 feet
3. The ball was at its highest point 1.125 seconds after it was tossed.
