Answer:

axis of symmetry: x=3, vertex: (3,23)

Step-by-step explanation:

-\frac{b}{2a}=-\frac{12}{-4}=3

axis of symmetry(x-value of the vertex): x=3

input this value into the function to get the vertex

-2(3)^{2}+12(3)+5

-18+36+5

18+5

23 is the y-value of the vertex

(3,23)

plz mark me brainliest. :)

A portion of a hiking trail slopes upward at about a 6° angle. To the nearest
DedPeter [7]

Answer:

12.6 feet

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

The slope is also the tangent of the angle of the opposite side (rise) divided by the adjacent side (run)

In this problem

we have

m=tan(6^o)

run=120\ ft

rise=?

substitute

tan(6^o)=\frac{rise}{120}

rise=tan(6^o)(120)=12.6\ ft

Choose the equations which have a greater rate of change than the graph.
NemiM [27]

Option C: y=\frac{3}{10} x is the equation that have a greater rate of change.

Explanation:

From the graph the coordinates are (0,0), (20,6), (40,12), (60,18) and (100,30)

We need to determine the rate of change.

The rate of change can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the any two coordinates in the formula, we get, the slope of the equation.

Let us substitute the coordinates (20,6) and (100,30)

Thus, we have,

m=\frac{30-6}{100-20}

Simplifying, we get,

m=\frac{24}{80}

Dividing, we get,

m=\frac{3}{10}

Also, the y - intercept of the equation is b=0

The equation of the line becomes y=\frac{3}{10} x

Thus, the equation that has a greater rate of change is y=\frac{3}{10} x

Hence, Option C is the correct answer.

The measure of a minor arc equals the measure of a(n) blank angles.
tresset_1 [31]

Answer:

option A is correct.

Step-by-step explanation:

Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°

Since, A minor arc is an arc smaller than a semicircle. A central angle which is subtended by a minor arc has a measure less than 180°.

The minor arc is equal to the measure of the central angle.

We could also see the angle from the figure attached to the answer.

Hence we will obtain an acute angle.

Hence, option A is correct.
