Answer:
f(0)=1
Step-by-step explanation:
The question asks us to find f(0). We want to find what f(x), or y is, when x is equal to 0.
f(x)=3^x
Therefore, we can substitute 0 in for x.
f(0)=3^0
Evaluate the exponent, 3^0.
Any number raised to the power of zero is equal to 1.
f(0)=1
Answer:
1
Step-by-step explanation:
f(0) = 3^0
f(0) = 1
anything to the 0th power = 1
The width of a rectangle is 5 inches. The length of the rectangle is twice the width. Find the perimeter of the rectangle.
PLZZZZZZZZ HELP
Answer: the perimeter of the rectangle is 30
Step-by-step explanation: so we know that the width of the rectangle is 5. Then it says that the length is two times more than the width....
5 times 2
Which is 10
Now all is left, you find the perimeter (all sides)
5+5+10+10
10+20
30
Therefore,
The perimeter of the rectangle is 30
Answer: 30
Step-by-step explanation: If the width is 5 and the length is twice the width then the length is going to be 10.
p=2(L+W)= 2(10+5)
2 x 15= 30

4th question help plzz with steps
I give brainly
Answer:
72 degrees
Step-by-step explanation:
A central angle equals the degree of the arc.
If the circumference is 20 and the arc is 4 than means the
arc is 4/20= 1/5 of the circumference.
A circles circumference is also always equal to 360 degrees.
So we need to find out what 1/5 of 360 is to find the degree of the arc.
So then 1/5*360= 72
so the Arc is equal to 72 degrees of the whole circle, which means the central angle is equal to 72 degrees as well.

Answer:
A. 13 ft
Step-by-step explanation:
Volume= [tex]\frac{4225pi }{3}[/tex]ft³
Height= 25
Volume= πr²[tex]\frac{h}{3}[/tex]
Volume= 3.14 ×r²×[tex]\frac{25}{3}[/tex]
[tex]\frac{157}{6}[/tex] r²= [tex]\frac{4225pi }{3}[/tex]
r²= [tex]\frac{4225\pi }{3}[/tex] × [tex]\frac{6}{157}[/tex]

Sumiko and Chung are shopping. Chung wants to buy a video game that costs $60, and Sumiko wants to buy a new pair of sunglasses for $80. In their possession, they have a gift card for $20 dollars, applied after taxes, and a 15 percent off coupon, applied before taxes. Sumiko and Chung want to use their remaining money to buy lunch, which they will split, at the mall. Assuming that taxes are 8.7 percent, who should use which savings option to ensure they have the most money remaining for lunch?
Answer:
1.83
Step-by-step explanation:
First, add the game and glasses. Write down the number you just got. Now, multiply by 0.15.
Take the second away from the first.
Now multiply that by 0.087
Finally, take 20 away

Dylan is wrapping a birthday present for his sister. The box the gift is in has a length of 6 inches, a width of 5 inches,
and a height of 3 inches. What is the minimum amount of wrapping paper Dylan will need to completely cover the
box?
TI
Answer:
126 square inches of wrapping paper
Step-by-step explanation:
To compute for the minimum amount of wrapping paper Dylan will need to completely cover the box, you have to compute the surface area of the box. The formula in getting the surface area of a rectangle is:
A = 2WL + 2LH + 2HW
Substituting the given measurements to the formula:
A = 2(5)(6) + 2(6)(3) + 2(3)(5)
A = 60 + 36 + 30
A = 126 square inches
Therefore, Dylan needs to purchase at least 126 square inches of wrapping paper to completely cover the box.

What scenario could be modeled by the graph below?
A. The number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5.
B. The number of pounds of apples, y, minus half the number of pounds of oranges, x, is at most 5.
C. The number of pounds of apples, y, plus two times the number of pounds of oranges, x, is at most 5.
D. The number of pounds of apples, y, plus half the number of pounds of oranges, x, is at most 5.
Answer:
I would believe that it is A.
Step-by-step explanation:
The fact that A has 5, and x is minus two times, 5/2= 2.5, and that is where the second arrowhead is pointing to on the x axis.
The number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5 which is correct option (A).
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + bc where 'm' and 'c' are real numbers.
It represents the line's slope-intercept form, which is written as y = mx + c.
This is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line
'c' is the y-intercept of the line
'x' is the independent variable
'y' (or f(x)) is the dependent variable
According to given graph,
A has a value of 5, and since x is negative two times, 5/2=2.5, which is where the second arrowhead on the x axis is pointing.
So, the total number of the pounds of apples, y minus two times, and the pounds of oranges, x, equals at most five pounds.
Hence, the number of pounds of apples, y, minus two times the number of pounds of oranges, x, is at most 5.

All the children of a class were asked to choose between the cartoon shows 'Shin Chan' and 'Tom and Jerry'.The ratio of children who selected the cartoon 'Shin Chan' to those who selected the cartoon 'Tom and Jerry', was 3:1.
If 45 kids selected 'Shin Chan', how many students are there in the class totally?
Answer:
There were 60 kids in class.
Step-by-step explanation:
Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:
children(Tom and Jerry) = children(Shin Chan)/3
children(Tom and Jerry) = 45/3 = 15
Therefore the number of children in the class is:
children(class) = children(Tom and Jerry) + children(Shin Chan)
children(class) = 15 + 45 = 60
There were 60 kids in class.

A veterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine, and that the number of milligrams, m, varies directly with the weight of the dog, w. The vet uses these steps to find the amount of medicine to give a 10-pound dog.
Step 1 Find the constant of variation.
k = StartFraction 0.5 Over 50 EndFraction = 0.01
Step 2 Write the direct variation equation.
m = 0.01 w
Step 3
Substitute 10 into the equation to find the dosage for a 10-pound dog.
10 = 0.01 w
Step 4
Solve for w.
10 = 0.01 w. w = 1000.

Answer:
960cbin
Step-by-step explanation:
Answer:
320
Step-by-step explanation:
The formula for the volume of a pyramid is V= (b x h)/3
v is the volume
b is the base you get it by multiplying the bases length and width in this case it would be 80 in( since 8 x 10 is 80)
h is the height in this case it would be 12 in
V= (b x h)/3
V= (80 x 12)/3
V= (960)/3
V= 320 in
If the volume of a cylinder 30 cm high 4620cm^3 find radius
Answer:
7 cm to 1 decimal place
Step-by-step explanation:
We need to know one formula in order to solve this question and it's the volume of a cylinder formula which is π × r² × h where 'r' is the radius and 'h' is the height, we want to work out the radius not the volume so we have to set up an equation to solve for the radius given the information that the volume of the cylinder is 4620 cm³ and the height is 30cm so
→ Step 1 form the equation
π × r² × h = 4620
→ Step 2, substitute in the values in this case we only need to substitute in the height
π × r² × 30 = 4620
→ Step 3, divide 30 from both sides to isolate π and r²
π × r² = 154
→ Step 4, divide both sides by π to isolate r²
r² = 154 ÷ π
r² = 49.0197224723
→ Step 5, square root both sides to isolate 'r'
r = 7.0014086063
So the radius of the cylinder is 7 cm to 1 decimal place
Answer:
7.00 cm.
Step-by-step explanation:
V = π r^2 h so
r^2 = V / π h
r = +√(V / πh)
r = +√( 4620 / 30π)
r = 7 .00cm.
