Step-by-step explanation:

Answer:

[tex]Length = 10ft[/tex]

[tex]Width = 15ft[/tex]

Step-by-step explanation:

Given

[tex]W= Width\\ L = Length[/tex]

[tex]Area = 150[/tex]

[tex]W=2*L- 5[/tex]

Required

Determine the dimension

Area is calculated as:

[tex]Area = L * W[/tex]

So, we have:

[tex]L * W = 150[/tex]

Substitute: [tex]W=2*L- 5[/tex]

[tex]L * (2*L-5) = 150[/tex]

[tex]L * (2L-5) = 150[/tex]

Open bracket

[tex]2L^2 - 5L = 150[/tex]

Rewrite as:

[tex]2L^2 - 5L - 150=0[/tex]

Expand

[tex]2L^2 -20L + 15L - 150 = 0[/tex]

Factorize:

[tex]2L(L -10) + 15(L - 10) = 0[/tex]

[tex](2L + 15) (L - 10) = 0[/tex]

Split

[tex]2L + 15=0[/tex] or [tex]L -10 = 0[/tex]

Solve for L

[tex]2L =-15[/tex] or [tex]L = 10[/tex]

L cannot be negative

So:

[tex]L = 10[/tex]

Substitute [tex]L = 10[/tex] in [tex]W=2*L- 5[/tex]

[tex]W = 2 * 10 - 5[/tex]

[tex]W = 20 - 5[/tex]

[tex]W = 15[/tex]

Hence:

[tex]Length = 10ft[/tex]

[tex]Width = 15ft[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

x^2 + 3x - 9 =0

By comparing with the equation ax^2+bx+c = 0,

we get,

a = 1, b=3, c = -9

we know the formula for x is,

x = (-b±√(b^2 - 4ac))/2a

x = (-3±√45)/2

x = (-3±3√5)/2

x = (-3+3√5)/2, (-3-3√5)/2

Answer:

2 solutions. x = -3/2 + 3/2 * sqrt(5) and x = -3/2 + -3/2 * sqrt(5)

Step-by-step explanation:

x^2 + 3x −9 = 0

For this equation: a=1, b=3, c=-9

1x^2 + 3x+ −9 = 0

Step 1: Use quadratic formula with a=1, b=3, c=-9.

x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex])/2a

x = (-3 ± [tex]\sqrt{3^2 - 4(1)(-9)}[/tex])/2a

x = (-3 ± [tex]\sqrt{45}[/tex])/2

x = -3/2 + 3/2 * sqrt(5) or x = -3/2 + -3/2 * sqrt(5)

Answer:

∠b = 68°

Step-by-step explanation:

Complementary angles are a pair of angles that, added together, equal 90°.

If ∠a = 22°, then the measure of∠b must equal 90° when added to that of ∠a.

To find the measure of ∠b, then, we can subtract ∠a from 90°.

90 - 22 = 68

The measure of ∠b, then, is 68°.

Answer:

[tex]\=x=82[/tex]

Step-by-step explanation:

From the question we are told that:

Data

[tex]\begin{center}\begin{tabular}{ |c|c|c|c|c|c| } 87& 91& 86& 82& 72&91 \\ 60& 77& 80& 79& 83&96 \end{tabular}\end{center}[/tex]

Generally the equation for Point estimate [tex]\=x[/tex] is mathematically given by

[tex]\=x=\frac{\sum_x}{n}[/tex]

[tex]\=x=\frac{87 +91+ 86+ 82 +72 +91+ 60+ 77 +80+ 79+ 83 +96}{12}[/tex]

[tex]\=x=\frac{984}{12}[/tex]

[tex]\=x=82[/tex]

Answer: $203

Step-by-step explanation: We first start out with the exponential decay model which is y=a(1-r)^t, then plug in the numbers of your problem:

-y=26,000(1-0.50)^7

-y=26,000*0.50^7

-y=26,000*0.0078125

-y=203.125

Then, after rounding to the nearest hundred dollars you get your answer....

:) hope this helped a bit

The value of the car 7 years after it was purchased will be $203.

A quantity lowers gradually at first during exponential decay before rapidly declining after that. Half-life may be calculated using the exponential decay formula, which is also used to estimate population decrease.

It is given that, A brand-new car costs $26,000 to buy, and every five years, its value decreases by 50%.

We have to find the value of the car 7 years after it was purchased

The exponential decay model, y=a(1-r)t, is where we begin. The data from your problem are then entered.

y=-26,000(1-0.50)^7

y=-26,000*0.50^7

y=-26,000*0.0078125

y=-203.125         (-ve shows the value is declining)

Thus, the car will be worth $203 seven years after it was bought.

Answer:

  (a)  75.5

Step-by-step explanation:

There are two ways you can work this.

Pythagorean theorem

Triangle CMP is a right triangle. CM = AC = 55. CP = CB -PB = 55 -15 = 40. Then length PM can be found from ...

  PM² +CP² = CM²

  PM = √(CM² -CP²) = √(55² -40²) = √1425 ≈ 37.749

The length MN is twice the length of PM, so is ...

  MN = 2×PM = 2×37.349 = 75.498

The length of MN is about 75.5.

__

Using chord relationships

The products of the different lengths for the same chord are the same for the crossed chords.

  AP×PB = MP×PN

We know MP = PN, so ...

  MP = √(AP×PB) = √((55+40)(15)) = √1425

As before, MN = 2×MP = 2√1425

  MN ≈ 75.5

Answer: 85.13

Step-by-step explanation:

We know:

Circumference = 2*3.14r

Area of a circle = 3.14r²

We need to find the radius given the circumference before solving for the area:

32.7 = 2*3.14r

32.7/6.28 = 6.28r/6.28

r = 5.20700637

Now that we know the radius, we can plug it in to find the area:

A = 3.14(5.20700637)²

A = 3.14(27.1129153)

A = 85.134554

Answer:

62 + 64 + 55 + s = 242

61 students will ride Bus #4.

Step-by-step explanation:

The equation I will use here is 62 + 64 + 55 + s = 242

62 + 64 + 55 + s = 242 {Going from left to right, subtract 62, 64, & 55 from 242}

64 + 55 + s = 180 {242 - 62 = 180}

55 + s = 116 {180 - 64 = 116}

s = 61 {116 - 55 = 61}

61 students will ride Bus #4.
