Step-by-step explanation:
- First write the given equation
- Now take all polynomials to left side.
Answer: 200.96 cm
Step-by-step explanation:
Area of a circle:
Since we don't have the radius, we have to find it.
What you gave me is the diameter which is 16 (cm) I suppose.
Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.
16/2=8cm
This is our radius.
Plug this into the area formula.
Answer:
5xy*(3y+2)
Step-by-step explanation:
(1): "y2" was replaced by "y^2".
Step by step solution :
Step 1 :
Equation at the end of step 1 :
10xy + (3•5xy2)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
15xy2 + 10xy = 5xy • (3y + 2)
Final result :
5xy • (3y + 2)
Answer:
The null hypothesis should be
The alternate hypothesis should be
Step-by-step explanation:
You wondered if the sugar content in energy drinks is really the same as labeled in the products. The disclosure on Red Bull 12 oz.
At the null hypothesis, we test if the sugar content is the same labeled, that is:
At the alternate hypothesis, we test if the sugar context is different from the labeled, that is, different of 12.
Answer:
1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.
2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased.
3. F = 4/R. This is inverse variation for the same reason as number 2.
4. m/n = 4. Direct variation. For the same reason as number 1.
5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.
6. R = cl/r². Joint variation.
7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r.
8. V= pir²h. Joint variation.
