Answer:

148.5 units^2

Step-by-step explanation:

First, find the area of the entire rectangle. The area is 180 because we have to  multiply 15*12.

Next, find the area of the triangle.  The area is 31.5 because we have to figure out 1/2(7*9)

Finally, you subtract 31.5 from 180.

Answer:

The slope-intercept form is y=\frac{1}{2}x+\frac{11}{2}

Step-by-step explanation:

To find the slope, use

m=\frac{y^2-y^1}{x^2-x^1}

Replace the x and y values with the points.

m=\frac{7-5}{3-(-1)}

Solve.

m=\frac{2}{4}

m=\frac{1}{2}

After that, find the y-intercept form.

Put the equation in point-slope form.

y-5=\frac{1}{2}(x+1)

Replace x with 0.

y-5=\frac{1}{2}(0+1)

y-5=\frac{1}{2}

Add 5 to both sides.

y=5\frac{1}{2}

Convert to improper fraction form.

The y-intercept is \frac{11}{2}

Now finally, write in slope-intercept form. (y=mx+b)

m is slope, b is the y-intercept.

32. The expression a^x means that a is to be used as a factor x times. Therefore, if a^x is squared, the result is
dybincka [34]

Answer:

B. a^2x

Step-by-step explanation:

squaring a^x gives. (a^x)²

by applying the rules of indices, ^2 multiplies x therefore making it a^2x

4. Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number. The
a_sh-v [17]
4.) The lateral area of a figure is the area of the figure with the exception of the bases.
Given a prism with right triangle bases, the lateral area of the prism is the sum of the areas of the rectangles making up the prism.
This is given by
Lateral area = (8.94)(41) + (4)(41) + (8)(41) = 366.54 + 164 + 328 = 858.54 ≈ 859 m^2

The surface area is the sum of the bases plus the lateral area. The area of a rectangle is given by half base times height.
Surface area = 1/2 x 8 x 4 + 1/2 x 8 x 4 + 859 = 16 + 16 + 859 = 891 m^2

5.) The surface area of a cylinder is given by pi r^2h where r is the radius = 12 inches and h is the height = 17 inches.
Surface area = π x (12)^2 x 17 = 2,448π = 7,690.62 in^2 ≈ 7,691 in^2

So the formula y= ax^2 first you must flip the equation so that gives us ax^2= y
Then divide both sides by x^2  giving us  <span><span>a<span>x^2/x^2 = y/x^2  so we would end up with  a= y/x^2  </span></span><span /></span><span><span /></span>
