Answer:

Yes, the total cost of Lacey lesson is a split function of hours scheduled

Step-by-step explanation:

The amount Lacey pays for each hour of golf = $15

The amount Lacey pays for equipment rental = $10

The amount Lacy pays for equipment rental for a 3 hours long lesson = $5

Therefore, we have

Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;

C = $10 + t × $15 for 0 ≤ t ≤ 3

C = $5 + t × $15 for t > 3

Therefore, the total cost of Lacey lesson is a split function of hours scheduled

Answer:

the answer for the question is c 2

Step-by-step explanation:

When someone receives a "pay raise", that means that their income/salary increases.

Jerold earns $865 in one week. He receives a 25% pay raise. That means his income has increased by 25% of what he currently earns in one week. We can calculate the percentage of something by converting that percent into a decimal and multiplying it with the value that percent is being applied to.

We can do this two ways.

The first way, we can convert 25% into 0.25, and multiply that with 865:

0.25 × 865 = 216.25

Then, we add $216.25 to Jerold's old salary, $865:

$865 + $216.25 = $1081.25

The second way does everything in one step. When you multiply a number by 1, you always get that same number for the answer.

1 × 33 = 33, 1 × 382 = 382...

So, instead of multiplying by 0.25 and then adding that to Jerold's old salary, we can multiply by 1.25 instead (1, his original salary, + 0.25, the difference between his old and new salary),.

1.25 × $865 = $1081.25.

You can use either method to calculate the answer, but the second method is more efficient.

The required equation model to determine the new weekly pay rate is x = 865[1 + 25%] or x = 865[1.25].

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Jerold's weekly pay rate is $865. He receives a 25% pay raise.
Let the new weekly pay rate be x,
According to the question,
x = 865 + 25% of 865
x = 865[1  + 25%]
x = 865[1.25]
x = $1081.25

Thus, the required equation model to determine the new weekly pay rate is x = 865[1 + 25%] or x = 865[1.25].

Answer:

Reflecting over the x-axis, vertical movement up 3 units.

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

Transformations of graphs

Step-by-step explanation:

Step 1: Define

f(x) = x + 1

g(x) = -x + 4

Step 2: Define

Multiplying -1 to x flips it over the x-axis, or known as a reflection. There is no vertical shrink/stretch.

To get to 1 to 4, we add 3. That means we will be moving the graph up 3 units.

Answer:

The sign on the 'x' changes, this implies a reflection.

g(x) = -f(x) = -(x+1) = -x -1

Now apply a vertical translation 'up 5' to f(x)

g(x) = -f(x) + 5 = (-x-1) +5 = -x +4

Answer:

3. 147 [tex]ft^{3}[/tex]  4. [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]

Step-by-step explanation:

3. Volume of a square pyramid = [tex](base.edge.length)^{2}[/tex] × [tex]\frac{height}{3}[/tex]

Variables:

V = volume

x = base edge length

h = height

V = [tex]x^{2}[/tex]  × [tex]\frac{h}{3}[/tex]

x = 7 ft

h = 9 ft

Plug the values in the equation:

V = [tex]7^{2}[/tex] × [tex]\frac{9}{3}[/tex]

V = 49 × 3

V = 147 [tex]ft^{3}[/tex]

4. Volume of cone = [tex]\pi r^{2} \frac{h}{3}[/tex]

Variables:

V = volume

r = radius

h = height

V = [tex]\pi r^{2} \frac{h}{3}[/tex]

r = 8ft /2 = 4 ft (radius is half of the diameter)

h = 10 ft

V =  [tex]\pi 4^{2} \frac{10}{3}[/tex]

V = [tex]\pi[/tex] × 16 × [tex]\frac{10}{3}[/tex]

V = [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]

okay so

117° + angle a = 180° (supplementary angle)

angle a = 180 - 117

= 63°

then angle a + angle b + 81° = 180° ( angle sum property)

so... 63° + angle b + 81° = 180

144 + angle b = 180°

angle b = 180 - 144

= 36°
