Step-by-step explanation:
Step-by-Step Explanation:
25^2 = 16^2 + b^2
625 = 256 + b^2
369 = b^2
19.2 = b
x^2 + 19.2^2 = 22^2
x^2 + 369 = 484
x^2 = 115
x = 10.7

The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.
We are provided with the equation V = 5000[tex]e^{0.05t}[/tex]
The equation can be simplified as
V = 5000 e0* (0.05t)
V= 250t
This linear equation can be plotted for different values of t which are
If t=0, V = 0
If t=1, V = 250
If t=2, V = 500
If t=3, V = 750
If t=4, V = 1000
If t=5, V = 1250
If t=6, V = 1500
If t=7, V = 1750
If t=8, V = 2000
If t=9, V = 2250
If t=10, V = 2500
If t=11, V = 2750
If t=12, V = 3000
If t=13, V = 3250
If t=14, V = 3500
If t=15, V = 3750
If t=16, V = 4000
If t=17, V = 4250
If t=18, V = 4500
If t=19, V = 4750
If t=20, V =5000
Now, we just have plot these 20 coordinates
The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

A. -28 + 2b = 53
B. 2b + 7 = 20
C. 6/7 + 18 = 16
D. b/2 + 7.4 = 1.4
Answers
Answer:
b/2 + 7.4 = 1.4 thus D. is the answer
Step-by-step explanation:
Solve for b:
b/2 + 7.4 = 1.4
Put each term in b/2 + 7.4 over the common denominator 2: b/2 + 7.4 = b/2 + 14.8/2:
(b/2 + 14.8/2) = 1.4
b/2 + 14.8/2 = (b + 14.8)/2:
((b + 14.8)/2) = 1.4
Multiply both sides of (b + 14.8)/2 = 1.4 by 2:
(2 (b + 14.8))/2 = 2×1.4
(2 (b + 14.8))/2 = 2/2×(b + 14.8) = b + 14.8:
b + 14.8 = 2×1.4
2×1.4 = 2.8:
b + 14.8 = 2.8
Subtract 14.8 from both sides:
b + (14.8 - 14.8) = 2.8 - 14.8
14.8 - 14.8 = 0:
b = 2.8 - 14.8
2.8 - 14.8 = -12:
Answer: b = -12

Luke made 25% of his free throws over the season if he shot 200 free throws how many did he make?
Answers
Based on the number of throws Luke had and the percentage he made, the number he made was 50 throws.
Number of Free Throws MadeThere were 200 free throws in the season and Luke was able to make about 25% of them.
The formula to find this is therefore:
= Number of free throws x Percentage made
Solving gives:
= 200 x 25%
= 50 throws
In conclusion, Luke made 50 throws.

Compound interest is interest calculated on the principal and the interest accrued in previous periods. It differs from simple interest where interest is not added to the principal when calculating interest for the next period. In mathematics, compound interest is usually represented by C.I.If the interest is compounded annually, then amount is given by [tex]A=P(1+\frac{r}{100} )^t[/tex] where " A " = Amount , " R " = annual interest rate , "T" = number of years , " P" is principal amount .
We have given principal amount = £800 , rate = 4% and time = 3 years .
Putting above values in equation (1) , we get
[tex]A=800(1-\frac{4}{100} )^3\\A= 800(1 -0.04)^3\\A=800(0.96)^3\\A=800\times 0.88\\A= \£707.78[/tex]
Note that the minus sign is due to depreciation .
On rounding off , amount will be £708 .

A ball is launched upwards from a height of 4 feet. The ball’s height as a function of time, in seconds, is modeled by the function h(t)= -16t^2 +80t +4. What is the time interval in which the ball has a height greater than 100 feet?
Answers
Answer:
Between 2 & 3 seconds. Or we can write it as 2<t<3
Step-by-step explanation:
t = elapsed time in seconds
h(t) = height of the ball at time t
So we just need to replace h(t) with 100 and start to solve. In the end, the answer will be t=2, or t=3 or we can write it as 2<t<3. You can check it by plugging in the number into the equation.

WHAT IS SPHERE ? HOW TO FIND ITS VOLUME ?In terms of geometry, a sphere is described as a collection of points that are spaced apart by a specific amount. The supplied point is referred to as the sphere's center, and the given distance from the sphere's center to the collection of points that make up the sphere is referred to as the sphere's radius.
Many everyday things, including balls and globes, are spheres. Finding a sphere's radius and entering it into the straightforward formula V = [tex]\frac{4}{3}[/tex]π [tex]r^{3}[/tex] will allow you to determine its volume.
CALCULATIONGiven: The radius of the tennis ball is 2.1cm and the radius of the golf ball is 2.0cm. the formula is V=4πr(to the 3rd power) /3 .
To find: Volume of tennis ball and golf ball .
Formula used: V = [tex]\frac{4}{3}[/tex]π [tex]r^{3}[/tex] .
pi(π) =[tex]\frac{22}{7}[/tex] .
We are given that
Radius of the tennis ball = 2.1 cm
radius of the golf ball =2.0 cm.
We need to find the volume of each ball
So , plugging the given values of radius in above formula
Volume of the tennis = [tex]\frac{4 * 22 * (2.1)^{3} }{3 * 7}[/tex] = 38.808 [tex]cm^{3}[/tex]
On simplification we get, volume of tennis ball = 38.808 [tex]cm^{3}[/tex]
Volume of the golf ball= [tex]\frac{4 * 22 * (2.0)^{3} }{ 3*7}[/tex] = 33.523[tex]cm^{3}[/tex]
On simplification we get, volume of golf ball = 33.523[tex]cm^{3}[/tex]
∴ The volume of tennis ball = 38.808[tex]cm^{3}[/tex]
Volume of golf ball = 33.523[tex]cm^{3}[/tex]

Morgan is visiting a city and wants to take a taxi. The driver tells Morgan that they charge per kilometer and
shows this table describing their cost:
Answers
The amount it would cost Morgan to travel 13 km is £32.5
Calculating CostFrom the question, we are to calculate how much it would cost Morgan to travel 13 km
From the given table, we have that
The cost of traveling 5 km is £12.50
and
The cost of traveling 10 km is £25
First, we will determine the cost of traveling 1 km
If the cost of traveling 5 km is £12.50
Then,
The cost of traveling 1 km will be £12.50/5
£12.50/5 = £2.5
The cost of traveling 1 km is £2.5
Now,
If the cost of traveling 1 km is £2.5
Then,
The cost of traveling 13 km will be 13 × £2.5
13 × £2.5 = £32.5
Hence, the amount it would cost Morgan to travel 13 km is £32.5
