Two plumbers charge and initial fee and an hourly rate. The equation y = 100 + 30.0 models plumber A's fee, where y is the total charge, in dollars, and x is the number of hours worked. The table shown represents plumber B's total charge for different number of hours. Plumber B Hours Total Charges (5) 105 2 그 160 2 215 Which statement about the plurnbers' charges is true?​

Answer:

20m

Step-by-step explanation:

Given the height reached by the ball modelled by the equation

h = -d² + 8d+4.

The velocity of the balk at its maximum height is 0. Hence

v = dh/dd = 0

v = -2d + 8

0 = -2d+8

2d =8

d =8/2

d = 4

Substitute d = 4 into the equation to get the maximum height reached

h = -(4)² + 8(4)+4

h =-16+32+4

h = -16+36

h = 20

Hence the maximum height reached by the ball is 20m

Answer:

X=-8

Step-by-step explanation:

81^(x-4)=9^3x

(9^2)^(x-4)=9^3x

9^(2x-8)=9^3x

Same base socompare both sides

So 2x-8=3x

2x-3x=8

-x=8

X=-8

So the value of X is -8

Answer:

[tex]a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24[/tex]

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

[tex]3x \: and \: - 6[/tex]

So the correct answer would be

[tex]3x - 6[/tex]

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

B) on a circle with radius 2

Step-by-step explanation:

got it right on edge :)

The 4th roots of 16i is located b) on a circle with radius 2

The complex number is given as:

Number = 16i

Take the fourth root

[tex]Root = \sqrt{16i[/tex]

Take the fourth root of 16

[tex]Root = 2\sqrt{i[/tex]

The number before the radicand represents the circle radius

Hence, the 4th roots of 16i is located b) on a circle with radius 2

Answer:

a. y = 3 × (x + 2)(x - 8)

b.  y = 3·(x - 3)² - 75

c) y =  3·x² - 18·x - 48

Step-by-step explanation:

The x-intercept of the quadratic equation are (-2, 0), (8, 0)

The stretch of the quadratic equation = 3

We have;

a. The factored form y = 3 × (x + 2)(x - 8)

b. From the vertex form, we have;

y = 3 × (x + 2)(x - 8) = 3·x² - 18·x - 48

y = 3·x² - 18·x - 48

The vertex form a(x - h)² + k

Where;

h = -b/(2·a) = 18/6 = 3

h = 3

k = c - b²/(4·a) = -48 - (18²)/12 = -75

The vertex form 3·(x - 3)² - 75

c) The standard form of the quadratic equation, y = a·x² + b·x + c

The standard form of the quadratic equation is y =  3·x² - 18·x - 48.

Answer:

-2 / 7 . Crown?

Step-by-step explanation:

1 / 7  + ( -3 ) / 7 = -2 / 7

Because the positive number is bigger than the negative number on a number line.

Negative numbers are on the left of a number line

Positive numbers are on the right of a number line

If you draw a number line you would go backwards 1 then -3, would become -2 because -2 is greater than -3

Hope this helps.
