Answer: 157.5

Step-by-step explanation:

Gina sold more than twice as many TVs as Ethan, because 19 > (2 * 8)

An equation is an expression composed of variables and numbers linked together by mathematical operations.

Ethan sold exactly eight TVs this quarter.

Ethan TV = 8

Gabriel sold more TVs than Ethan, hence:

Gabriel TV (G) > 8

Gabriel TV > 8

Gina sold exactly three more TVs than Gabriel and Ethan combined

Gina TV = Gabriel TV + 8 + 3

Gina TV > 8 + 8 + 3

Gina TV > 19

Frank sold exactly twice as many TVs as Gina, hence:

Frank TV = 2 * Gina TV

Frank TV > 2 * 19

Frank TV > 38

Gina sold more than twice as many TVs as Ethan.

The table is not linear.

Answer:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)=45[/tex]

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

Step-by-step explanation:

When calculating composite functions, work from the inside out.

Given composite function:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)[/tex]

First use the graph to find f(1):

[tex]\implies f \left( g \left( f \left( 1 \right) \right) \right)= f \left( g \left(-4\right)\right)[/tex]

Now use the graph to find g(-4):

[tex]\implies f \left( g \left(-4\right)\right)=f(-6)[/tex]

As the graph does not show the value for f(x) when x = -6, we need to use the equation:

[tex]\implies f(-6)=(-6)^2-2(-6)-3=45[/tex]

Therefore:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)=45[/tex]

------------------------------------------------------------------------------

Given composite function:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)[/tex]

First use the graph to find g(0):

[tex]\implies g \left( f \left( g \left( 0 \right) \right) \right)=g \left( f \left( -2 \right) \right)[/tex]

Now use the graph to find f(-2)

[tex]\implies g \left( f \left( -2 \right) \right)=g \left(5 \right)[/tex]

Finally, use the graph to find g(5):

Therefore:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

The measure of m<1 is 108 degrees from the provided figure.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Lines are therefore one-dimensional objects, even if they can exist in spaces with two, three, or more dimensions.

From the diagram, we have the following parameters

m<2 = 72 degrees

Required parameters

The measure of angle m<1

From the figure, the sum of the interior angle is equivalent to 180 degrees, that is:

m<1 + m<2 = 180

m<1 = 180 - m<2

m<1 = 180 - 72

m<1 = 108 degrees

Hence the measure of m<1 from the given figure is 108 degrees.

The amount of red blood cells contained in 40 cubic millimeter is 1.08×10⁸

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.

For example If Mary is paid for a job $50 per day.

How much will she earn in 10 days.

She will earn 50×10 = $ 500 in 10 days

Similarly, 1 cubic millimeter contains 5.2× 10⁶ red blood cells

then, 40 cubic millimeter will contain 40× 5.2×10⁶

= 108×10⁶ = 1.08 × 10⁸ red blood cells

Therefore the amount of red blood cells contain in 40cubic millimeter of blood is 1.08× 10⁸

Team Tackle's score was 28 points. And team Sack's score was 9 points.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

During the 2005 football season, Team Tackle beat Team Sack by 19 points. If their combined scores totaled 37.

Let 'x' be the Tackle's score and 'y' be the Sack's score. Then the equations are given as,

x + y = 37        ...1

x = y + 19        ...2

From equations 1 and 2, then we have

y + 19 + y = 37

2y = 18

y = 9

Then the value of 'x' is given as,

x = 9 + 19

Use the equation for the sum of the first n terms:

Answer:

[tex]S_7=6554[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7 cm}\underline{Sum of the first $n$ terms of a geometric series}\\\\$S_n=\dfrac{a(1-r^n)}{1-r}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]

Given geometric series:

[tex]2-8+32-...+a_n[/tex]

The first term (a) of the sequence is 2:

[tex]\implies a=2[/tex]

To find the common ratio (r), divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{-8}{2}=-4[/tex]

To find the sum of the first 7 terms, substitute the found values of a and r into the formula, along with n = 7:

[tex]\implies S_7=\dfrac{2(1-(-4)^7)}{1-(-4)}[/tex]

[tex]\implies S_7=\dfrac{2(1-(-16384))}{5}[/tex]

[tex]\implies S_7=\dfrac{2(16385)}{5}[/tex]

By using the fact that the sum of the interior angles must be 180°, we wil see that:

x = 110°.

First, remember that the sum of the interior angles of a triangle is alway equal to 180°.

We also can see that the interior angle that is adjacent to x can be written as:

a = 180° - x

Then the sum of the interior angles will give:

30° + 80° + (180° - x) = 180°

30° + 80° - x = 0

110° - x = 0

110° = x

Step-by-step explanation:

The solution is Option A.

The coordinate of the triangle after the translation is given by A' ( 0 , -3 ) with 4 units right and 4 units down

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the coordinate of the triangle be represented as A

Now , the coordinate A = A ( -4 , 1 )

Now , the coordinate of the triangle after translation is A' ( 0 , -3 )

when there is a translation of the coordinate A by 4 units to the right , we get

A to 4 units right = A ( -4 + 4 , 1 )

The new coordinate of A = A ( 0 ,  1 )

Now , A to 4 units down , we get

The coordinate of A' = A' ( 0 , 1 - 4 )

The coordinate of A' = A' ( 0 , -3 )

Hence , the translated coordinate is A' ( 0 , -3 )

Charise can pick 1/3 pound of berries in 15 minutes. This is her unit rate. To find out how many pounds of berries she can pick in 4 hours, we need to multiply this unit rate by the number of 15-minute intervals in 4 hours.

240 minutes / 15 minutes = 16 (four-hour intervals)

So the amount of berries Charise can pick in 4 hours is:

1/3 pound/15 minutes * 240 minutes = (1/3) * 16 = 16/3 = 5.333 pounds of berries.

Answer:

The domain of a function is the set of all input values (x-values) for which the function produces a valid output (y-value). In the case of the function H(x) = x+2/x^2+4x+4, we need to find the values of x for which the denominator x^2+4x+4 is not equal to zero.

x^2+4x+4 = 0

(x+2)^2 = 0

The denominator is always non-zero as the square of any real number is always positive. Therefore, the function H(x) = x+2/x^2+4x+4 is defined for all real values of x. Therefore, the function H(x) does not have any values that are not in its domain.

Vector sums

(a, b, e) + (c, d, f) = (a + c, b + d, e + f)

Vector multiplication by a scalar

α · (a, b, c) = (α · a, α · b, α · c)

If we know that U = (5, 0, 0), V = (0, 5, 0) and W = (0, 0, 5), then the following operations are below:
