Answers
Answer:
a) 53%
b) 12%
Step-by-step explanation:
you need to use the equation given
y = -6.83x + 108
x is the rank
y is the probability of winning 1st game
a) for rank 8th or x=8
y = -6.83(8) + 108 = 53.36 or 53%
b) for rank 14th or x=14
y = -6.83(14) + 108 = 12.38 or 12%

True or False? The blue radius is perpendicular to the green chord.
Answers
The statement that the blue radius is perpendicular to the green cord is false
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

A picnic favorite is strawberry Shortcake! Each batch of strawberry
shortcake calls for 1 2/5 pounds of cake and 3/4 pound of strawberries. If
you want to make 5 batches of strawberry shortcake, how many pounds
of cake and strawberries do you need to buy?
Answers
To make 5 batches of strawberry shortcake you'll need 7 pounds of cake and 3 3/4 pounds of strawberries for a total sum of 10 3/4 pounds.
Step-by-step explanation:1 - Write an equation to represent the problem
For every batch, it takes 1 2/5 pounds of cake and 3/4 pounds of strawberries
therefore
[tex]Let \\\ n_c = pounds~of~cake \\\n_s = pounds~of~strawberries \\\b = number~of~batches[/tex]
[tex]n_c = 1 \frac{2}{5}b \\\n_s = \frac{3}{4}b[/tex]
For ease of math, lets convert these to decimals
[tex]n_c = 1.4b \\\n_s = 0.75b[/tex]
2 - Plug in your variables to solve for cake and strawberries
Cake
[tex]n_c = 1.4b \\\ n_c = 1.4(5)\\n_c = 7[/tex]
To make 5 batches of strawberry shortcake you will need 7 pounds of cake
Strawberry
[tex]n_s = 0.75b \\\n_s = 0.75(5) \\\n_s = 3.75[/tex]
to make 5 batches of strawberry shortcake you will need 3.75 or 3 3/4 pounds of strawberries --- Totalling in at 10.75 pounds or 10 3/4

David kicks a ball off the ground. After t seconds, it’s height, h (in feet), is given by the formula h=-16t^2+80t. How many seconds does the ball reach its maximum height? What is the maximum height reached by the ball?
Answers
Answer:
The ball reaches its maximum height at 2.5 seconds
The maximum height is 100 feet
Step-by-step explanation:
Maximum Value of Functions
We use the derivative of a function to find its maximum or minimum value over a given interval.
Given a function y=f(x), the first derivative criterion establishes if x=a is such that:
f'(a)=0, and f''(a) < 0 then x=a is a maximum of f.
The height h in feet of a ball after t seconds is:
[tex]h(t)=-16t^2+80t[/tex]
Find the first derivative:
[tex]h'(t)=-32t+80[/tex]
Equate to 0:
[tex]-32t+80=0[/tex]
Subtract 80:
[tex]-32t=-80[/tex]
Divide by -32:
[tex]t = -80 / (-32) = 2.5[/tex]
t=2.5 seconds
Find the second derivative:
h''(t)=-32
Since h''(t) is always negative, then
The ball reaches its maximum height at 2.5 seconds
To find the value of the maximum height, substitute t=2.5 into the function:
[tex]h(2.5)=-16(2.5)^2+80*2.5=-100+200 = 100[/tex]
The maximum height is 100 feet
What would be the slope for a line perpendicular to y = -¼x + 2?
Answers
Answer:
m perpendicular= [tex]-\frac{1}{notlinear}[/tex]
Step-by-step explanation:
So if our slope is negative, the slope perpendicular to that would be the positive reciprocal.
Let m= -A/B so the slope perpendicular to that would be B/A
Here our slope is -1/4 so the slope perpendicular to that would be -(-4/1) which is just 4
Therefore your perpendicular slope would be 4

The property tax on a $60,000 home is $1,500. At this rate what will the property tax be on a home worth $75,000?
Answers
Answer:
The answer is $1,875
Step-by-step explanation:
1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750
2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000
3. So then $1,500 + $375 = $1,875

1. [tex]\frac{x}{15}[/tex] = 0.85
2. x = 12.75
Step-by-step explanation:
First, we do 12 divided by 15, which is 0.80 (80%). The question is asking how much consecutive free throws is needed to raise it to 85%.
So, and equation we make is:
[tex]\frac{x}{15}[/tex] = 0.85, where x represents the number of free throws.
Now, we solve.
Multiply each side by 15 to solve for x.
x = 12.75
12.75 consecutive free throws is needed to raise the percent to 85%.
