Answer:

Conner's work is correct

Step-by-step explanation:

Operations With Exponents

We need to use the rule to find the product of two or more exponential expressions:

[tex]x^m\cdot x^n\cdot x^p = x^{m+n+p}[/tex]

We need to multiply:

[tex](3^5 6^8)(3^9 6^{10})[/tex]

Base 3 is treated independently from base 6, so we have two groups of operations:

[tex](3^5 6^8)(3^9 6^{10})=3^{5+9} 6^{8+10}[/tex]

Adding the exponents:

[tex](3^5 6^8)(3^9 6^{10})=3^{14} 6^{18}[/tex]

Thus, Conner's work is correct

Answer:

Part A

The Quadratic Function to model the total number of bricks the stack is f(x) = x²

Part B

The number of bricks we will have for 50 rows is 2500 bricks

Step-by-step explanation:

Part A

Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c

We have;

When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0

∴ c = 0

When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1

∴ a + b = 1...(1)

When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2  = 4

∴ 4·a + 2·b = 4...(2)

Multiply equation (1) by 2, and subtract it from equation (2) gives;

4·a + 2·b - 2×(a + b) = 4 - 2 × 1

2·a = 2

a = 1

From equation (1), we have;

b = 1 - a = 1 - 1 = 0

b = 0

∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²

Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²

Part B

If there are 50 rows in the stack, then we have, x = 50

Therefore;

f(50) = 50² = 2500

The number of bricks we will have for 50 rows is f(50) = 2500 bricks

Answer:

C

Step-by-step explanation:

Here, originally, we are told that the point Q has coordinates (-2,1)

Now, its dilated point has the coordinates (-8,4)

what we can observe here is the the shape original polygon was dilated by a factor of 4 to give the image

Now the point R’ is (0,8)

To get the point R , we simply divide each coordinate by 4

Thus, we have (0/4 , 8/4)

This is same as option C

Step-by-step explanation:

3x+ 7(x+1) = 2(6x+5) -2x

Distribute

3x+7x+7 = 12x+10-2x

Combine like terms

10x+7 = 10x+10

Subtract 10 from each side

10x+7-10x = 10x+10-10x

7 = 10

This is not a true statement so there are no solutions

Step-by-step explanation:

The formula for the lateral surface area of a cylinder is

=>2πrh

In the question:

The lateral surface area of a cylinder is 288π square centimeters.

The height of the cylinder is 16 centimeters.

Hence:

288π => 2πrh

288π => 2 × π × r × 16

288π => 32πr

r => 288π/32π

r => 9 cm

The formula of Diameter is 2 × radius

= 2 × 9 cm

Diameter =>18 cm

The diameter of the cylinder in centimeters is 18 cm
