<span>9y+y = y(9 + 1) = 10y
answer is 10y

if </span><span>9y^2 then it should be 9y times y = 9y^2

hope it helps</span>

vitfil [10]

Answer:

The volume of platform

= 11 ft³

Step-by-step explanation:

The height of the Platforms are

The food prep area = 5 ft

Storage shelf = 6 ft

Side of rectangle = b width of platform = d

Therefore area of platform = b·d

Volume of the food prep area platform = Area × height = 5 b·d ft³

Volume of the storage shelf platform = Area × height of storage shelf platform = 6 b·d ft³

Therefore the total volume = Volume of food storage platform + volume of storage shelf platform = 5 b·d ft³ + 6·b·d ft³ = 11·b·d ft³

geniusboy [140]

Answer: C. He used too few trials for the sample space.

Step-by-step explanation:

Given: Josh used a standard deck of 52 cards to conduct an experiment.

As half of the cards in the deck were red.

If we take sample space= 52 cards

Then probability of getting a red card $=\frac{1}{2}$

But Josh took 8 cards as sample space which is not enough for the sample space.

therefore, C. is the right answer. "He used too few trials for the sample space."

Sketch the region of integration for the following integral. ∫π/40∫6/cos(θ)0f(r,θ)rdrdθ

solong [7]

Answer:

The graph is sketched by considering the integral. The graph is the region bounded by the origin, the line x = 6, the line y = x/6 and the x-axis.

Step-by-step explanation:

We sketch the integral ∫π/40∫6/cos(θ)0f(r,θ)rdrdθ. We consider the inner integral which ranges from r = 0 to r = 6/cosθ. r = 0 is located at the origin and r = 6/cosθ is located on the line x = 6 (since x = rcosθ here x= 6)extends radially outward from the origin. The outer integral ranges from θ = 0 to θ = π/4. This is a line from the origin that intersects the line x = 6 ( r = 6/cosθ) at y = 1 when θ = π/2 . The graph is the region bounded by the origin, the line x = 6, the line y = x/6 and the x-axis.
