Step-by-step explanation:

Separate each rectangle and square and find the area of each. Don't forget the ones on the back

Answer:

Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:

y= 2x -8

Step-by-step explanation:

To find  the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1, we will follow the steps below;

since the line is parallel to y=2x + 1, then the will have the same slope. That is; m₁ = m₂

comparing  y = 2x + 1 to y = mx + c

m= 2

we will substitute m= 2 x= 5  and y = 2  into y = mx + c and then solve for c

y = mx + c

2 = 2(5) + c

2 = 10 + c

subtract 10 from both-side of the equation

2-10 = 10 -10 + c

-8 = c

c=-8

To find our equation, we will substitute m = 2  and c=-8 into y=mx + c

y = 2x - 8

Therefore, the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1      is    y= 2x -8

Answer:

A) 6 < c < 18

Step-by-step explanation:

A triangle is known to have 3 sides: Side a, Side b and Side c.

For a triangle, one of the three sides is longer than the other two sides. (The only exception is when we are told specifically that a triangle is an equilateral triangle, where all the 3 sides are equal to each other).

To solve the above question, we would be using the Triangle Inequality Theorem.

The Triangle Inequality Theorem states that the summation or addition of the lengths of any two sides of a triangle is greater than the length of the third side.

Side a + Side b > Side c

Side a + Side c > Side b

Side b + Side c > Side a

For the above question, we have 2 possible side lengths for the third side of the triangle. We are given in the above question,

side (a) = 6

side (b) = 12

Let's represent the third side as c

To solve for the above question,we would be having the following Inequality.

= b - a < c < b + a

= 12 - 6 < c < 12 + 6

= 6 < c < 18

Therefore, the possible side lengths for the triangle is the above question is Option A) 6 < c < 18

Answer:

There is a local maximum at the point (-1,6), therefore, for x = -1

Step-by-step explanation:

Notice that the function adopts values smaller than 6 to the left of x = -1, and to the right of it:

(-3, -2), (-2, 0) to the left of x = -1 where the function's value is 6

and (0, 0), and (1, -2) to the right of x = -1

therefore, it looks like (-1, 6) is a maximum, that is for x = -1, where the function renders a value of 6.

Answer:

D is the correct answer

Answer:

X=20

70 x 2 for the other side = 140

every triangle has 180 degrees

180-140=40

There are 40 remaining degrees

there are two x's so we divide by 2

40 = X2

20 = X

Answer:

(new - original) / original * 100 %

Step-by-step explanation:

To find a percent loss,

Take the new amount

Subtract the original amount

(new - original)

Then divide by the original

(new - original) / original

Multiply by 100 percent

(new - original) / original * 100 %

That is the percent loss

find a percent loss,

Take the new amount

Subtract the original amount Divide by original multiply by 100

Answer:

It seems to be D)9 from intervals 1 to 3...

Step-by-step explanation:

Can't really explain that well, but the rate of change in an exponential function should always be decreasing or increasing. Instead of it being constant like a linear equation.

I.E. Not additive, instead to find it we need to divide.

[tex]\frac{27}{3} =9[/tex]

So, it should be 9. However, It does not seem to be maintained for the values after 3. Oh well!

Hope this helps!

The average rate of change of the function is 12.

The rate of change function represents the rate at which one quantity changes in relation to another. Simply put, the rate of change is the difference between the amount of change in one item and the comparable amount of change in another.

Rate of change = [ y₂ - y₁ ] / [ x₂ - x₁ ]

The rate of change for x₁ = 1 to x₂  = 3 at x₁ = 1 ,y₁ = 3 and at x₂= 3, y₂ = 27.

Rate of change =  [ y₂ - y₁ ] / [ x₂ - x₁ ]

                          = [ 27 - 3 ] / [ 3 - 1 ]

                          = [ 24 / 2 ]

                          = [ 12 ]

Hence, the correct option is A.

Answer:

Step-by-step explanation:

Elevators are a safer way that using a ladder, or any other option, because it has really good foundations, so you won't fall, and it has a floor which you can stand on safely.

Stairs are also safer than ladders, because you can have more estability on the surface, preventing any falls.

At last, ramps are also safer than ladders, but less safe than elevators or stairs, because they have an inclined surface, so you can slide.

Now, if we analyse these four options, we can say that their difference is about the frictional surface each of them have, and the null slope some of them have. For example, a ladder is dangerous, because you don't enough surface to step on, also, the friction of its surface is lower, that means you can easily fall. But, elevators, stairs and ramps have greater coefficient of friction on their surface, and also, they have a greater surface area.

Answer:

x = 0 or x = 4

Step-by-step explanation:

x² + y² = 25 and y = -2x + 5

Here,

x² + y² = 25 ...(1)

Now,

Put the value of y = -2x + 5 in equation (1)

we get,

x² + (-2x + 5)² = 25

x² + {(-2x)² + 2(-2x) (5) + (5)²} = 25

x² + {4x² - 20x + 25} = 25

x² + 4x² - 20x + 25 = 25

5x² - 20x = 25 - 25

5x² - 20x = 0

5x(x - 4) = 0

5x = 0 or x - 4 = 0

x = 0/5 or x = 4

x = 0 or x = 4

x = 0, x = 4
