Could someone help this question? I need help please and thank you​

Answer:

The answer is 120 inches

Step-by-step explanation:

900 is the area the area of a rectangle is A=lw

So 900=30w

900/30=w

30=w

multiply 30 by 4 to get the perimeter

Answer:

k = 14

Step-by-step explanation:

Given:

x⁴ + kx² + 49

Find:

Value of k

Computation:

x⁴ + kx² + 49

(x²)² + (k)(x²) + 7²

we know that;

a² + 2ab + b²

On compare;

k = 2 x 7

k = 14

Answer:

X=5

Step-by-step explanation:

3+12x=63

Subtract 3 from both sides

12x=60

Divide both sides by 12

X=5

Answer:

Ummm... Ok... Answer: X = 187 / 39 OR X = 4.794872

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

/3  + 1 2  = 63

3(​x/3 + 12x) = 3.63

Simplify

37x = 189

Divide both sides of the equation by the same term

37x = 189

37x / 37 = 189 / 37

Simplify

x = 187 / 39

OR

x = 4.794872

Answer:

The sketch tool to indicate what Edwin is describing as the parabola's "turning point'' is described below in details.

Step-by-step explanation:

We can see in graph that it intersect X axis and it is open upward it means turning point is below X axis, we can find turning point by find maximum value of Y If open downward and minimum value, if open upward here we can find that minimum point is (3, -5). also you can draw axis of symmetry parabola and finds its intersection with turning point can also be named vertex of parabola.

Answer:

[tex]x<-6[/tex]

Step-by-step explanation:

[tex]3x-2>5x+10[/tex]

Add 2 to both sides

[tex]3x-2+2>5x+10+2[/tex]

Simplify

[tex]3x>5x+12[/tex]

Subtract [tex]5x[/tex] from both sides

[tex]3x-5x>5x+12-5x[/tex]

Simplify

[tex]-2x>12[/tex]

Multiply both sides by [tex]-1[/tex] (reverse the inequality)

[tex](-2x)(-1)<12(-1)[/tex]

Simplify

[tex]2x<-12[/tex]

Divide both sides by [tex]2[/tex]

[tex]\frac{2x}{2} <\frac{-12}{2}[/tex]

Divide the numbers: [tex]\frac{2}{2} =1[/tex]

[tex]=x[/tex]

Divide the numbers: [tex]\frac{-12}{2}[/tex]

Apply fraction rule: [tex]\frac{-a}{b} =-\frac{a}{b}[/tex]

[tex]=\frac{12}{2}[/tex]

Divide the numbers: [tex]\frac{12}{2} =6[/tex]

[tex]=-6[/tex]

[tex]x<-6[/tex]

Answer:

x < -6

Answer:

Step-by-step explanation:

For some growth factor f each year, the growth factor over 20 years is given as ...

  f^20 = 1 +0.51 = 1.51

Then the growth factor in 10 years is ...

  f^10 = (f^20)^(1/2) = √1.51 ≈ 1.22882

__

a) In the 10 years between 1998 and 2008, the price of a basic haircut would rise to ...

  $18 × 1.22882 ≈ $22.12 . . . price in 2008

__

b) In the 10 years between 2003 and 2013, the price of a basic haircut would rise to ...

  $19.95 × 1.22882 ≈ $24.51 . . . price in 2013

Answer:

[tex]y = \frac{3}{2} x-8[/tex]

Step-by-step explanation:

Firstly, let's get y by itself in the equation.

[tex]y = \frac{3}{2}x + 5[/tex]

Parallel lines have the same slope, but not the same y intercept. So we have an equation like this:

[tex]y = \frac{3}{2}x + b[/tex]

To find b (aka the y-intercept), we need to plug in the ordered pair into the equation like this:

[tex]-5 = \frac{3}{2}(2) + b[/tex]

Now solve:

[tex]-5 = \frac{6}{2} + b\\-5 = 3 + b\\-8 = b[/tex]

We have found the y-intercept, now we can write the full equation:

[tex]y = \frac{3}{2} x-8[/tex]

I hope this helps!!

Answer:

6.50w

Step-by-step explanation:

Given that :

Weight ________ Cost ($)

1 ______________6.50

2 _____________ 13.00

3 _____________ 19.50

Cost of package that weighs w pounds

If one pound = 6.50

2 pounds = 13.0

Then, the cost per pound = $6.50

Hence, cost of package that weighs w pounds will be ;

$6.50 * w = $6.50w

Answer:

Step-by-step explanation:

We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.

Answer:

D.) x = 5.29

Step-by-step explanation:

first find the last angle measure 180-90-54=36

use law of sines to find x

sin90/9=sin36/x

(sin90)(x) = (sin36)(9)

(sin90)(x) = 5.29

x = 5.29

Step-by-step explanation:

V = πr²*(h/3)

diameter = 6, r=3

V = π*9*(24/3)

Answer:

- x³ + x² + x - 3

Step-by-step explanation:

(3x³ + 2x - 3) - (4x³ - x² + x)

3x³ + 2x - 3 - 4x³ + x² - x

3x³ - 4x³ + x² - x + 2x - 3

- x³ + x² + x - 3

Answer:

Step-by-step explanation:

B) The first step is to calculate the monthly payment using a present value (PV) of $59,000 , monthly interest rate of 7.60 /12 = 0.633333 %, and 60 periods, which = $1185.04 ; the second step is to add $50 to this monthly payment giving the new monthly payment of $1235.04 ; the last step is to calculate the time required to pay off the loan = 57.0740 months.

Answer:

4 * 14 = 56

Step-by-step explanation:

56/2 = 28

28/2 = 14

14/2 = 7

7/7 = 1

56 = 2 * 2 * 2 * 7

56 = (2 * 2) * (2 * 7)

56 = 4 * 14
