Answer:

8

Step-by-step explanation:

the table shows the function f(x) = 2x²

Rate of Change:  [f(1) - f(3)] / 1-3

= 2(1²) - 2(3²) / -2

= 2 - 18 / -2

= -16/-2

= 8

Answer:

Those answers are correct

Answer:

Midpoint is (0, -4)

Step-by-step explanation:

x-coordinate of midpoint = (-7 + 7)/2 = 0/2 = 0

y-coordinate of midpoint = (3 - 11)/2 = -8/2 = -4

Midpoint is (0, -4)

Answer:

(0,-4)

Step-by-step explanation:

(x1 + x2/2,  y1 + y2/2)

(-7 + 7/2 ,  3 + -11/2)

(0/2,  -8/2)

(0,-4)

Answer:

12 square inches

Step-by-step explanation:

[tex]{( \sqrt[3]{{x}^{2}})}^{6} = {({x}^{ \frac{2}{3}})}^{6} = {x}^{ \frac{2}{3} \times 6 } = {x}^{2 \times 2} = {x}^{4} \\ [/tex]

So the answer is the second option which is,

[tex] {x}^{4} [/tex]

Answer:

54° and 110°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

(9)

19x - 26 + 7x - 2 = 180

26x - 28 = 180 ( add 28 to both sides )

26x = 208 ( divide both sides by 26 )

x = 8

Then

∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°

(10)

21x - 33 + 14x + 3 = 180

35x - 30 = 180 ( add 30 to both sides )

35x = 210 ( divide both sides by 35 )

x = 6

Then

∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°

The inscribed angle YVW is half the measure of its intercepted arc YW, so

arc YW = 2 × 87° = 174°, then

arc XW = 174° - 64° = 110°

Cyclic quadrilateral is drawn inside a circle. The measure of the ∠EFG is 54°. The measure of the angle made by the arc XW is 110°.

A cyclic quadrilateral is a quadrilateral that is drawn inside a circle. The sum of the opposite angle of the cyclic quadrilateral is always equal to  180°.

9.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for

[tex]\angle GDE + \angle EFG = 180^o\\\\19x - 26 + 7x - 2 = 180\\\\26x - 28 = 180\\\\26x = 208\\\\x = 8[/tex]

Now, substitute the value of x, in order to get the measure of the ∠EFG,

[tex]\angle EFG = 7x - 2\\\\\angle EFG = 7(8) - 2\\\\\angle EFG = 56 - 2\\\\\angle EFG = 54^o[/tex]

The measure of the ∠EFG is 54°.

10.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for

[tex]\angle YXW + \angle YVW = 180^o\\\\21x - 33 + 14x + 3 = 180\\\\35x - 30 = 180\\\\35x = 210\\\\x = 6[/tex]

Now, substitute the value of x, in order to get the measure of the ∠YVW,

[tex]\angle YVW = 14x + 3\\\\\angle YVW = 14(6) + 3 \\\\\angle YVW= 84 + 3 \\\\\angle YVW = 87^o[/tex]

As we know that in the inscribed∠YVW, the ∠YVW is half the measure of its intercepted arc YW, therefore, We can write it as,

arc YW = 2 × 87° = 174°, and

arc XW = 174° - 64° = 110°

The measure of the angle made by the arc XW is 110°.

Hello! answer: 39

Step-by-step explanation:

Formula for triangles area: base × height ÷ 2

Formula for squares area: base × height

5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39

Answer:

39

Step-by-step explanation:

5x3=15

15/2=7.5

7.5x4=30

3x3=9

30+9=39

Answer:

119 in

Step-by-step explanation:

you just have to find the area of each shape individually and add them!

As we can see, we have a square base and 4 triangles. each triangle has the same area because the base is a square and they all have a height of 5. so, the area of a triangle is

[tex]a = \frac{1}{2} bh[/tex]

thus, each triangle is

[tex]a = \frac{1}{2}( 7 \times 5) = \frac{1}{2} (35) = 17.5[/tex]

since we have 4 triangles we can add this together 4 times or multiply by four.

[tex]4 \times 17.5 = 70[/tex]

now, we just need to add the area of the base. the area of a square is

[tex]a = {s}^{2} [/tex]

or

[tex]a = s \times s[/tex]

so, the area of the square is

[tex]a = {7}^{2} [/tex]

or

[tex]a = 7 \times 7[/tex]

which both equal 49.

now, we can add 49 to our sum of the area of our triangles, so

70+49= 119in

-Gage Millar, Algebra 2 tutor

Answer:

Step-by-step explanation:

since  cos ^2  = 1/4 then cos = 1/2

b/c cot is  tan inverted, then  cot =  cos / sin

so we also know that  [tex]\sqrt{3}[/tex]/2  will be sin for this same Ф

then

cot =  (1/2)  /  ( [tex]\sqrt{3}[/tex]/2  )

cot = 1 / [tex]\sqrt{3}[/tex]

since Ф is in quad III

we know both parts of the fraction will be negative

cot = -1 / -[tex]\sqrt{3}[/tex]

but we would normally write that as a positive

Answer: 0.02 per year

Step-by-step explanation:

When given the per capita birth rate and the per capita death rate, the per capita growth rate can be calculated as:

= per capita birth rate - per capita death rate
