Is this right or wrong ?

Answer:

see screenshot 1.

feel free to copy the graph.

f(0)=-5

notice that anything to the power of zero is one (because its dividing by itself). so we are left with A, -5

f(1)=-10

notice that anything to the power of 1 is just itself, so we multiply-5 by 2 here

A is negative, so the graph will be facing down

the value of B is is greater than 1, meaning the graph will be growing [down].

Part B

see screenshot 2 everything is flipped over the y-axis

Part C

see screenshot 3. remember what "to the power of zero" and "to the power of one" means

hope it helps. greetings from Europe

Hello! answer: 48

Step-by-step explanation:

3 × 19 - 9 = 48

7 × 19 - 1 = 132

48 + 132 = 180 so... 48 is the measure of ABC

I seem like it's multiple choice, I don't think you really need an explanation

Answer:

C

Step-by-step explanation:

If we round up the 3/4 cup of sugar to 1 cup to make it easier, and then multiply by 2 because the 3/4 cup of sugar only makes half a dozen cupcakes, then we will get 2 cups of sugar which is an overestimate of how much is needed. If we multiply it again by 3 because he needs 3 times the amount of sugar, we get 6 cups of sugar because we rounded it up. Since we know 3/4 is less than 1, we can assume that 6 cups of sugar is more than needed.

Answer:

A = 2914 in²

Step-by-step explanation:

A = bh

A = 62(47)

A = 2914

Hope this helps!

Answer: The first one because b*h and 62 is the base and 47 is the height and I did 62*47 and that equals 2914.

Answer:

7.1

Step-by-step explanation:

Use the trig ratio tan to find b

4.5 x tan (23) = b = 7.14668887526

7.1

Answer:

b ≈ 1.9

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )

4.5 × tan23° = b , then

b ≈ 1.9 ( to the nearest tenth )

Answer:

Quedan 153 sillas

Step-by-step explanation:

Primero sabemos que en una sala de teatro tenían 7 filas, y en cada una de esas filas habían 23 sillas.

Entonces, originalmente, el número total de sillas es 7 veces 23:

S = 7*23 = 161

Luego sabemos que quitan 8 de esas sillas, entonces el número de sillas que quedan es la diferencia entre el número original de sillas, 161, y 8, que nos da:

S = 161 - 8 = 153

Quedan 153 sillas

Given:

A segments is from (−6,−1) to (6, -9).

A point divides the line segment into a ratio of 3 to 1.

To find:

The coordinates of the points.

Solution:

Section formula: If a point divides a line segment in m:n, then

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

The point divides the line segment in 3:1, so by using section formula, we get

[tex]Point=\left(\dfrac{3(6)+1(-6)}{3+1},\dfrac{3(-9)+1(-1)}{3+1}\right)[/tex]

[tex]Point=\left(\dfrac{18-6}{4},\dfrac{-27-1}{4}\right)[/tex]

[tex]Point=\left(\dfrac{12}{4},\dfrac{-28}{4}\right)[/tex]

[tex]Point=\left(3,-7\right)[/tex]

Therefore, the coordinates of the required point are (3,-7).

Answer:

[tex]Students = \frac{1}{50}[/tex]

Step-by-step explanation:

Given

[tex]Track = \frac{1}{30}[/tex]

[tex]Pizza = \frac{3}{5}[/tex]

Required

The fraction of students in the school that ate Pizza

To do this, we simply multiply the fraction of track students and those among them that ordered pizza.

So, we have:

[tex]Students = Pizza * Track[/tex]

[tex]Students = \frac{3}{5} * \frac{1}{30}[/tex]

[tex]Students = \frac{1}{5} * \frac{1}{10}[/tex]

[tex]Students = \frac{1}{50}[/tex]

Answer:

the last one : the range of the function is all real numbers less than our equal to 9.

Step-by-step explanation:

it is a parabola that opens up only down. that means all the calculated y-values go deeper and deeper into lower and negative values the more right or left we go on the x-axis.

the maximum y-value we have at the vertex with y=9. no other x-value can generate a bigger y-value.

that's why the last answer option is right.

An Outlier is a number that does not fit in a graph or a data set, like it could be abnormally big or abnormally small.

Answer:

x = 8

y = 4 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 30 = 4/x

x sin 30 = 4

x = 4 / sin 30

x = 4 / ( 1/2)

x = 8

tan theta = opp /adj

tan 30 = 4/y

y tan 30 =4

y = 4 / tan 30

y = 4 / ( 1/ sqrt(3))

y = 4 sqrt(3)

Answer and Step-by-step explanation:

To solve, we need to use Trigonometric Functions.

These functions include Sine, Cosine, and Tangent.

- Each one has its own rule to follow when solving.

θ = Angle

sin(θ) = [tex]\frac{Opposite.Side}{Hypotenuse}[/tex]

cos(θ) = [tex]\frac{Adjacent.Side}{Hypotenuse}[/tex]

tan(θ) = [tex]\frac{Opposite.Side}{Adjacent.Side}[/tex]

For this problem, we will only be using the trigonometric functions of Sine and Tangent.

Start by finding x.

sin(30) = [tex]\frac{4}{x}[/tex]

Multiply x to both sides.

x × sin(30) = [tex]\frac{4}{x}[/tex] × x

x(sin(30)) = 4

Divide both sides of the equation by sin(30).

x(sin(30)) ÷ (sin(30)) = 4 ÷ (sin(30))

x = [tex]\frac{4}{sin(30)}[/tex]

Simplify in calculator.

x = 8

Now find the value of y.

tan(30) = [tex]\frac{4}{y}[/tex]

Multiply y to both sides.

y × tan(30) = [tex]\frac{4}{y}[/tex] × y

y(tan(30)) = 4

Divide both sides of the equation by tan(30).

y(tan(30)) ÷ (tan(30)) = 4 ÷ (tan(30))

y = [tex]\frac{4}{tan(30)}[/tex]

Simplify in calculator.

y = [tex]4\sqrt{3}[/tex]

x = 8

y = [tex]4\sqrt{3}[/tex]

Answer:

19 measures the median

Step-by-step explanation:

The dot plot is not shown, but the question can still be answered.

We have:

[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]

[tex]n = 8[/tex]

Calculate the median position using:

[tex]Median = \frac{n + 1}{2}th[/tex]

[tex]Median = \frac{8 + 1}{2}th[/tex]

[tex]Median = \frac{9}{2}th[/tex]

[tex]Median = 4.5th[/tex]

4.5th means the median is the mean of the 4th and 5th item.

We have:

[tex]4th = 18[/tex]

[tex]5th = 20[/tex]

So:

[tex]Median = \frac{18 + 20}{2}[/tex]

[tex]Median = \frac{38}{2}[/tex]

[tex]Median = 19[/tex]

Answer:

2.8592933268

Step-by-step explanation:

tan(72) = 8.8/x

=> x = 8.8/tan(72) = 2.859293326849

The length of x is 3.

A triangle in which one of the interior angles is 90° is called a right-angled triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

According to the given problem,

Perpendicular = 8.8

Base = x

Let the Hypotenuse be h,

∅ = 72°

We know,

                sin∅ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]

            ⇒ sin72 = [tex]\frac{8.8}{h}[/tex]

            ⇒ 0.95 = [tex]\frac{8.8}{h}[/tex]  

            ⇒ 0.95h = 8.8

            ⇒ h = [tex]\frac{8.8}{0.95}[/tex]

            ⇒ h = 9.3

Now, applying Pythagoras theorem,

Hypotenuse² = Perpendicular² + Base²

⇒ 9.3² = 8.8² + x²

⇒ 9.3² - 8.8² = x²

⇒ x² = 9.05

⇒ x = √9.05

⇒ x = 3

Hence, we can conclude the value of x to be 3.
