If f(x) = 6x+7 find f(q+1)

Answers

Answer:

6q + 13

Step-by-step explanation:

Given

f(x) = 6x+7

To find f(q+1),

substitute x with q+1 in the given equation:

f(q + 1) = 6(q + 1) + 7 = 6q + 6 + 7 = 6q + 13

Answer:

Given :-

f(x) = 6x + 7

Solution :-

Let's put c as q + 1 and f as 6

6(q + 1) + 7

(6 × q) + (6 × 1) + 7

6q + 6 + 7

6q + 13

A cyclist rolls down a hill. He starts from rest and after 8 s he is traveling at 13.6m/s. What is his acceleration?

Answers

Answer:

1.7 m/s^2

Step-by-step explanation

acceleration is change in velocity / time

so we do 13.6 - 0 = 13.6 gives us change in velocity

13.6/8 = 1.7 m/s^2 gives acceleration

What is the surface area of the regular pyramid given below?
A. 280 units2
B. 329 units2
C. 189 units2
D. 140 units2

Answers

The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

Area of a Pyramid

From the question, we are to calculate the surface area of the regular pyramid

The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base

∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]

Surface area of the pyramid = 2bh + b²

Where b is the base

and h is the perpendicular height of each triangular faces

In the given diagram,

b = 7

h = 10

∴ Surface area of the pyramid = 2×7×10 + 7²

Surface area of the pyramid =  140 + 49

Surface area of the pyramid = 189 units²

Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

What is x or solve for x

Answers

Answer:

x = 8

Step-by-step explanation:

The measure of an arc is equal to the angle at the centre subtended by the arc.

The sum of the 3 arcs = 180° , then

5x + 6 + 83 + 51 = 180

5x + 140 = 180 ( subtract 140 from both sides )

5x = 40 ( divide both sides by 5 )

x = 8

Answer:

[tex]\boxed{\tt x=58^{\circ}}[/tex]

Step-by-step explanation:

From the given diagram, we see that ∠YOZ and ∠XOY are complementary angles.

Complementary angles: two angles with measures that add up to 90°.

[tex]\tt m\angle XOY+m\angle YOZ=90^{\circ}[/tex]

[tex]\tt \angle XOY+\angle YOZ=90^{\circ}[/tex]

[tex]\tt 32^{\circ}+x=90[/tex]

Subtract 32 from both sides:

[tex]\tt 32^{\circ}+x-32^{\circ}=90^{\circ}-32^{\circ}[/tex]

[tex]\tt x=58^{\circ}[/tex]
