Answer:

The solution of $\frac{1}{4}x \leq 2$ is $\mathbf{x\leq 8}$

Graph of the solution is attached in the figure below.

Step-by-step explanation:

We need to the graph the solution of $\frac{1}{4}x \leq 2$

First we will solve to find value of x

$\frac{1}{4}x \leq 2$

Multiply both sides by 4

$\frac{1}{4}x\times 4 \leq 2\times 4 \\x\leq 8$

So, the solution of $\frac{1}{4}x \leq 2$ is $\mathbf{x\leq 8}$

Graph of the solution is attached in the figure below.

The graph contains both number line and on graph paper also.

Answer:

The surface area of a cylinder is the sum of the areas of the two bases and the area of the lateral surface. If the height of the cylinder is doubled, the area of the lateral surface is doubled, but the areas of the bases remain the same.

Use the identity (x2+y2)2=(x2−y2)2+(2xy)2 to determine the sum of the squares of two numbers if the difference of the squares of

Answer:

The sum of the squares of two numbers whose difference of the squares of the numbers is 5 and the product of the numbers is 6 is 169

Step-by-step explanation:

Given : the difference of the squares of the numbers is 5 and the product of the numbers is 6.

We have to find the sum of the squares of two numbers whose difference and product is given using given identity,

$(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2$

Since, given the difference of the squares of the numbers is 5 that is $(x^2-y^2)^2=5$

And the product of the numbers is 6 that is $xy=6$

Using identity, we have,

$(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2$

Substitute, we have,

$(x^2+y^2)^2=(5)^2+(2(6))^2$

Simplify, we have,

$(x^2+y^2)^2=25+144$

$(x^2+y^2)^2=169$

Thus, the sum of the squares of two numbers whose difference of the squares of the numbers is 5 and the product of the numbers is 6 is 169

Brenda throws a dart at this square-shaped target:

Klio2033 [76]

Answer: See below

Step-by-step explanation:

Area of the square = l*w = 11*11 = 121

Area of the circle = pi r^2 = pi*1^2 = 3.142

Part A

P(hitting the circle) = 3.142 / 121 = 0.026 which is closer to 0.

Part B

P(hitting the outside portion) = 1 - 0.026 = 0.974 which is closer to 1.

Please help me out with this problem!!!!!!

guapka [62]

Answer:

Step-by-step explanation:

The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.

This is because such inequalities represent half planes which are divided by the corresponding lines.

Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.
