Complete the table to investigate dialations of exponential functions.
Answer:
a = 1, b = 3, c = 1, d = 2, e = 6, and f = 8
Step-by-step explanation:
The given exponential functions are;
2ˣ, 3·2ˣ, and [tex]2^{3 \cdot x}[/tex]
Let f(x) = 2ˣ, h(x) = 3·2ˣ, and g(x) = [tex]2^{3 \cdot x}[/tex]
From the table for investigating the dilations of exponential function, we have;
a = f(0) = 2⁰ = 1
b = h(0) = 3·2⁰ = 3 × 1 = 3
c = g(0) = [tex]2^{3 \times 0}[/tex] = 2⁰ = 1
d = f(1) = 2¹ = 2
e = h(1) = 3·2¹ = 3 × 2 = 6
f = g(1) = [tex]2^{3 \times 1}[/tex] = 2³ = 8.
1) Supposed that you have an account with the overdraft
protection. Your account balance is $40.00, you spend
$85.00 at a grocery stores. The bank charge you $30.00
every time you overdraft the account. What is your
account balance after the overdraft and the bank fee?
A) -$60.00
B) -$75.00
C) -$80.00
D) -$70.00
Answer: B) -$75.00
========================================================
Explanation:
Draw a vertical number line. Plot 40 on this line. Then move down 85 units to arrive at 40-85 = -45. The negative indicates that you're in debt.
Then move down another 30 due to the overdraft fee and we have -45-30 = -75 as the bank balance.
-------------------
Put another way:
Start at $40. If you spend $40, then your balance is $0. You need to spend another $45 to get all of the groceries (since the grocery bill is 40+45 = 85 dollars). That's where the -45 comes from, to indicate you're 45 dollars in debt. This is before the overdraft fee kicks in. Adding on that fee gets a total debt of 45+30 = 75 dollars. So that's why the final balance is -75 dollars.

On the swim team, for every 10 girls there are 7 boys. If there are 21 boys on the swim team, how many girls are there?
Answer:
30 girls
Step-by-step explanation:
Every 10 girls there are 7 boys.
So if there are 3 groups of 7 boys, there will be 30 girls.
Check:
10 girls: 7 boys
+10 girls: 7 boys
+10 girls: 7 boys
= 30 girls: 21 boys

-8b + 4(1 + 5b) = -6b - 14
Answer:
b = -1
Step-by-step explanation:
-8b + 4 + 20b = -6b - 14
12b + 4 = -6b - 14
18b + 4 = -14
18b = -18
b = -1

You bought 8 bags of dog food and 2 boxes of dog treats for a total of $135. Your friend bought 6 bags of dog food and 4 boxes of dog treats for a total of $110. Each bag of dog food costs the same amount. Each box of dog treats costs the same amount. Write a system of equations, then find the cost of one bag of dog food.
Answer:
8f + 2t = $135 - - (1)
6f + 4t = $110 - - (2)
$16
Step-by-step explanation:
Given that:
f = dog food
t = dog treat
8f + 2t = $135 - - (1)
6f + 4t = $110 - - (2)
From (1)
4f + t = 67.5
t = 67.5 - 4f
Put t = 67.5 - 4f in (2)
6f + 4(67.5 - 4f)= 110
6f + 270 - 16f = 110
-10f = 110 - 270
-10f = - 160
f = 16
One bag of dog food = $16

Answer: C) 10cm
Step-by-step explanation:
help me please. i need it
Answer: See explanation
Step-by-step explanation:
m∠A and m∠O are alternate interior angles so they're congruent.
m∠A = m∠O
m∠A = 65°
AM and SO are congruent sides
AM = SO
AM = 86
m∠S and m∠M are alternate interior angles so they're congruent.
m∠S = m∠M
m∠S = 60°
ON and NA are congruent sides.
ON = NA
ON = 75
m∡SNO, m∠S, and m∠O form a triangle so they should add up to 180°
m∡SNO + m∠S + m∠O = 180°
m∡SNO + 60 + 65 = 180
m∡SNO + 125 = 180
Subtract both sides by 125
m∡SNO = 55°

A recipe requires 1\4 of a cup of cranberries for 1 batch. How many beaches of scones can be made using 6 1/2 cups of cranberries?
Answer:
26
Step-by-step explanation:
1 batch is 1/4 cups of cranberries.
This means that we have to find the number of groups of 1/4 in 6 1/2 cups to find the number of batches.
(The decimal forms of these numbers are 6.5 and 0.25)
6.5/0.25=26
There are 26 batches

Math help find the rise.
Answer:
-16
Step-by-step explanation:
The equation for a slope is rise/run. You know from the question that the slope is -4/5 in its simplest form. However, the run in its original form is 20.
So if the run is 5 in its simplest form, but 20 in its original form, then this means the slope must have been simplified by dividing both the original rise and the original run by 4, because 20/4 = 5.
That also means we can find out the original rise by doing the inverse of what we did above. We can multiply the rise in its simplest form by 4 to get the original. That gives us -16 (because -4*4 = -16).
