Match the graph of the function with the function rule.
A. y = 1 • 4x
B. y = 2 • 4x
C. y = 3 • 10x
D. y = 10 • 4x
Answer:
D. y = 10 • 4x
Step-by-step explanation:
Answer: As seen from the graph, the y intercept is (0,0.5)
plugging this value in each equation:
y=1*4^x
plugging x as 0 and y as 0.5
lhs≠rhs
plugging x as 0 and y as 0.5
lhs = rhs
y= 1/2 x 4x
..............................................................................................................................................................................................................................................................................................
Answer:
D) y= 10*4^x
Step-by-step explanation:
Replace each function with x = 0
A)
B)
C)
D)
If you check the graph with x = 0, the value of y is between 8 and 12 so the only probably answer acoording to the alternatives is D) which gives y = 10 when x = 0

4/54 + 10/27
Answer:
24/54 or 4/9
Step-by-step explanation:
Make both denominators the same
Things you need to do
• 4/54 (Stays)
• 10/27 (Times by 2 to make denominator of 27 to 54)
Operation:
4/54 + 20/54
24/54 (You can leave in this form)
24/54 is the final answer
Alternative answer:
Lowest term form is
4/9 (Which 24/54 ÷ 6)
4/9 is the final answer

Evaluate the formula: x−2y=5 for when x=−3
Step-by-step explanation:
so, just use x = -3 in the equation.
-3 - 2y = 5
-2y = 8
y = -8/2 = -4
that was the whole thing.
Answer:
x-2y=5 x-3
×=2y-5 =x-3
x=3y=x-3

Answer: Choice B
[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]
===============================================================
Explanation:
Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is
c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)
This represents the length of the vector <-4,7>
Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.
The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

Question 8
The radius of a car wheel is 12 inches. How far will the car travel in 20 revolutions of the wheel?
The distance the car will travel in 20 revolutions of the wheel is 1507.96 inches.
Given that :
Radius of wheel , r = 12 inches
Number of revolutions = 20
The Circumference of the wheel = 2πr
Circumference of the wheel = 2 × π × 12 = 24π
The distance the car will travel after 12 revolutions of the wheel will be :
Number of revolutions × Circumference of wheel
20 × 24π = 480π = 1507.96 inches

Which equation corresponds to the following word problem?
Cory spends $6.50 on snacks at a gas station. He also buys gas, which costs $2.78 per gallon. If he spends a total of $24.00 at the gas station, how many
gallons of gas did he buy? Let g equal the number of gallons of gas.
(1 point)
O 6.509 +2.78 = 24.00
O 2.789 -6.50 = 24.00
O 6.50g - 2.78 = 24.00
2.789 +6.50 = 24.00
Answer:
Cory bought 6.30 gallons of gas at the gas station.
Step-by-step explanation:
total amount = cost of snacks + amount spent on gas
[tex]$\$ 24.00=\$ 6.50+\$ 2.78 \mathrm{~g}$[/tex]
[tex]$\$ 2.78 \mathrm{~g}=\$ 24.00-\$ 6.50$[/tex]
[tex]$\$ 2.78 \mathrm{~g}=\$ 17.50$[/tex]
[tex]$g=\frac{\$ 17.50}{\$ 2.78}$[/tex]

Answer:
please mark me as brianlist
Step-by-step explanation:
a. log_a 64 = log_a 4³ = 3 log_a 4
= 3 (1.585) = 4.755
b. log_a 1/16 = log_a 4`² = -2 log_a 4
= -2(1.585) = -3.17
c. log_a 36 = log_a 4×9 = log_a 4 + log_a 9
