Answer:
A = 388.58 cm^2
Step-by-step explanation:
For a cone whose base has a radius R, and a hypotenuse S, the area is:
A = pi*R^2 + pi*R*S
Where pi = 3.14
In this case, we can see that the diameter is: 15cm
Then the radius, half of the diameter, is:
R = 15cm/2 = 7.5cm
The hypotenuse is 9cm, then S = 9cm
A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2
Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:
A = 388.58 cm^2
Answer:
A. 4
Step-by-step explanation:
1. Use the SLOPE FORMULA: M= rise/run= y2-y1/x2-x1
2. Plug in the two coordinates that were plotted on the equation: (1,1) & (3,9)
3. Label the coordinates
( 1 , 1 ) = ( x1, y1 )& ( 3, 9 ) = ( x2, y2 )
4. SOLVE & PLUG IN
m = 9 - 1 / 3 - 1 = 8 / 2
5. Simplify 8/2 (Divide by 2)
6. answer: 4/1 = 4
To add, subtract, multiply or divide the number given to get a whole number or an integer
Answer:
1. A. 1
2. D.
Step-by-step explanation:
Properties used:
- Power of a Power Property
- Product Property
- Quotient Property
- Zero Exponent Property
1. First, let's deal with the numerator.
can be turned into by using the Power of a Power Property.
And then use the Product Property,
So now, our fraction is this:
All number over itself in a fraction is equal to 1. But you can also do this the mathmatic way using the Quotient Property: or . Which then you plug the numbers in: . And since we know that in Zero Exponent Property: , we can see that . So either way, we get 1.
So the answer is 1, which is A
2. Power of a Power Property:
So plug the numbers in the property: =
Product Property:
We plug the equation in with turned into ---
So the answer is , which is D
