Step-by-step explanation:

Distribute:

(4+3)(−2+4)

4(−2+4)+3(−2+4)

Distribute:

4(−2+4)+3(−2+4)

[tex]-8x^{2} +16+3(-2+4)[/tex]

Distribute:

Answer:

56.52

Step-by-step explanation:

This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52

Answer:

177.475 [tex]inches^{2}[/tex]

Step-by-step explanation:

Since the formula for finding the area of a full circle is A = π[tex]r^{2}[/tex], area equals pi times radius squared, we fill out the formula and solve.

A: unknown

Pi: 3.14

Radius: diameter is 12, so you divide it by 2, which is 6.

A = 3.14 x 6 squared.

using pemdas, you do exponents first,

A = 3.14 x 36

A ≈ 113.04

Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,

113.04/2

= 56.52

So, the area of the semicircle is 56.52 [tex]inches^{2}[/tex]

Answer:

106.2

Step-by-step explanation:

length x width x height

Answer:

106.2ft³

Step-by-step explanation:

To find volume for a cube we need to multiply the height x length x width

or H x L x W so that means we do 6 x 3 x 5.9 = 106.2

Answer:

17

Step-by-step explanation:

To evaluate the expression, subtract 8² from 81:

81 - 8²

8² = 8 × 8 = 64

81 - 64 = 17

Answer:

A

Step-by-step explanation:

q(x) is the same as y, so in other words, it was asking you, what is x when y = 0. The solutions of this graph are -4 and a decimal number somewhere near 1.6, and since there is no 1.6 or a decimal number as a choice, its -4 which is the other answer of the graph.

Answer:

The exponential equation is y = -2×(1/2)^x

Step-by-step explanation:

1) The horizontal asymptote of the function is the x axis (always nice)

2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)

3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:

Answer:

Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.

Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

Answer:

[tex]92\ yd^2[/tex]

Step-by-step explanation:

The given figure is a trapezoid, the formula for finding the area of a trapezoid is the following,

[tex]A=\frac{h(b_1+b_2)}{2}[/tex]

Where (h) is the height of the figure, and ([tex]b_1[/tex]) and ([tex]b_2[/tex]) are the bases. It is given that the height is (8) and ([tex]b_1[/tex]) is (8). The value of ([tex]b_2[/tex]) can be found by adding the value of ([tex]b_1[/tex]) to the "overhang" that ([tex]b_2[/tex]) has over ([tex]b_1[/tex]). Thus, ([tex]b_2[/tex]) is ([tex]8+7[/tex]) or rather ([tex]15[/tex]). Now substitute the values into the equation and solve for the area of the trapezoid,

[tex]A=\frac{8(8+15)}{2}[/tex]

[tex]=\frac{8(23)}{2}[/tex]

[tex]=4(23)[/tex]

[tex]=92[/tex]

Answer:

Step-by-step explanation:

Expense = 75%

Percentage of amount left = (100 -75)% = 25%

25% of 360 = 0.25* 360 = 90

Remaining amount left with Sue = $ 90

Answer:

15/14

Step-by-step explanation:

= 6/8 x  10/7

= 6/4 x 5/7

Multiply the numbers: 6 x 5 = 30

= 30/4x7

Multiply the numbers:

4 x 7 =28

Cancel the common factor (2):

= 15/14

Answer: The length must be at least 95 ft. squared. Pick the line with the filled in left circle, and the right side is an arrow. Put the left side that's filled in on 95 (middle line between 90 and 100).

Step-by-step explanation: Divide the minimum total area by the minimum width. The answer is the minimum length.

Length x Width = Area

20 ft. x 95 ft. = 1900 ft. sq

Answer:

The continuous closed line that makes the boundary of a two-dimensional shape is known as the perimeter. It’s easy to work out the perimeter of a shape with straight edges, such as a square, because you simply add the lengths of each edge together. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge. That formula is

Step-by-step explanation:

P = \frac{1}{2} πd + dP=

​

πd+d

where ​d​ is the diameter of the semi circle.

Apply the number pi (π) to the formula

Pi is a circle's circumference divided by its diameter and is always the same value, 3.14.
