Let's calculate the circumference ~

[tex]\qquad \sf  \dashrightarrow \: c = \pi d[/tex]

[tex]\qquad \sf  \dashrightarrow \: c = 3.14 \times 6[/tex]

[tex]\qquad \sf  \dashrightarrow \: c =18.84 \: ft[/tex]

The angle m∠UVW can be found using angle of circumference rule in geometry. Therefore, m∠UVW = 67°

An angle at the circumference of a circle is half the angle at the centre standing on the same arc.

In other words, the angle at the centre of a circle is twice the angle at the circumference.

Therefore,

m∠UVW = 134 / 2

m∠UVW = 67 degrees

Step-by-step explanation:

Answer:

B.  The equation of the linear function is y = 3x + 2

D.  The rate of change of the linear function is 3.

Step-by-step explanation:

First find the slope by choosing two ordered pairs and using the slope formula:

[tex]\textsf{let}\:(x_1,y_1)=(2,8)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(3,11)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{11-8}{3-2}=3[/tex]

Now use the Point-slope form of linear equation with the found slope and one of the points to create the equation of the linear function:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-8=3(x-2)[/tex]

[tex]\implies y=3x + 2[/tex]

The rate of change of a linear function is its slope.

Therefore,

B.  The equation of the linear function is y = 3x + 2

D.  The rate of change of the linear function is 3.

Using the interactive ruler, we can determine that it is 4 Units from the dilation's center to the image and pre-image.

This virtual instrument, which appears on the computer screen and is also known as an Interactive Teaching Program (ITP) ruler, is used to measure a shape's lines and sides.

Given, we need to find the distance in units between points C and A

Using the interactive ruler, we can determine that the separation between points C and A is 2 units.

Therefore, it takes 1.5 units to get from point C to point A'.

Answer:

  h(x), g(x), f(x)

Step-by-step explanation:

The axis of symmetry of a parabola is the vertical line through its vertex.

__

The equation is written in vertex form:

  f(x) = a(x -h)² +k . . . . . vertex (h, k), scale factor 'a'

The vertical line through the vertex is x=h.

Your equation is ...

  f(x) = -2(x -4) +2

so (h, k) = (4, 2) and the line of symmetry is x=4.

__

The given equation can be written in vertex form:

  g(x) = 5x² -10x +7

  g(x) = 5(x² -2x) +7

  g(x) = 5(x² -2x +1) +7 -5 . . . . complete the square

  g(x) = 5(x -1)² +2

so (h, k) = (1, 2) and the line of symmetry is x=1.

__

Your problem statement tells us ...

  h(x) = -(x +2)² +2

so (h, k) = (-2, 2) and the line of symmetry is x=-2.

The coordinates of the vertex can also be read from the graph: (-2, 2).

__

The rank of the functions is the order of {-2, 1, 4}, or h(x), g(x), f(x).

Answer:

A

Step-by-step explanation:

Here [ a, b ] = [ 2, 6 ], thus

f(b) = f(6) = -  + 70 = - 64 + 70 = 6

f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66

average rate of change =  =  = - 15 → A

y = -4x - 1

the gradient of the parallel line will be the same as the given line so you just need to change the y intercept

Answer:

x = 70°

Step-by-step explanation:

Since in triangle ABC (Check the image)

=> AB = AC

Therefore, ∠B = ∠C

From Angle Sum property of a triangle,

=> ∠A + ∠B + ∠C = 180°

=> x + 55 + 55 = 180

=> x +110 = 180

=> x = 70°

Answer:

The original value of the car.

Step-by-step explanation:

The 21,500 would be the a value of the function, as it is before the parentheses. The a value of an exponential function is a constant, and it is the y-intercept of that function, meaning in a real-world application, it would be where the values start at. In this case, the 21,500 is where the price of the car starts at, i.e., the original value of the car.

Answer:

C   [tex]3 \frac{7}{8} + (-6\frac{1}{4})[/tex]

Step-by-step explanation:

+ × - = -

Example:

5 × -3 = -15

+(-5) = -5

then:

3 7/8 - 6 1/4

= 3 7/8 + (-6 1/4)

we have that

[tex]y=-x^2+36[/tex]

we know that

Is the equation of a vertical parabola open down

so

the vertex is a maximum

step 1

convert the equation of the parabola in the vertex form

[tex]y=-x^2+36[/tex]

[tex]y-36=-x^2[/tex]

the vertex (h,k) is the point (0,36)

Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)

Part b) The points on the graph where the height of the tunnel is zero feet is when y=0

so

for y=0

[tex]-x^2+36=0[/tex]

[tex]x^2=36[/tex]

[tex]x=(+/-)6[/tex]

the points are (-6,0)  and (6,0)
