11x=99

x= 9°

Answer:

∠CBD = 54°

Step-by-step explanation:

∠ABC = 90°

∠ABD + ∠CBD = ∠ABC

4X + 7X -9 = 90

11X = 90+9

11X = 99

X = 99/11

X=9°

∠CBD = (7X -9)° = 7 * 9 - 9 = 63-9 = 54°

Answer:

$36

Step-by-step explanation:

The amount spent on cloths is 1/3

The amount earned from washing the car is $5

Amount at the end of the week is $29

Let the amount earned that week be x

Then amount spent on cloths = 1/3x

so the equation is

x- 1/3 x+$5=$29

2/3 x=29-5

2/3 x= 24

x=(24*3)/2= $36

Answer:

See explanation

Step-by-step explanation:

Let the given equation be:

[tex]5 {x}^{2} - 400 = 0[/tex]

This implies that:

[tex]5 {x}^{2} = 400[/tex]

Divide through by 5 to get;

[tex] {x}^{2} = 80[/tex]

Take square root to obtain:

[tex]x = \pm \sqrt{80} [/tex]

This implies that

[tex]x = \pm4 \sqrt{5} [/tex]

[tex]x = - 4 \sqrt{5} \: or \: x = 4 \sqrt{5} [/tex]

Answer:

x = [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Given a quadratic in standard form, ax² + bx + c : a ≠ 0

Then the axis of symmetry is a vertical line with equation x = h

where h is the x- coordinate of the vertex.

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = 5x² - 3x + 5 ← is in standard form

with a = 5 and b = - 3, thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-3}{10}[/tex] = [tex]\frac{3}{10}[/tex]

Thus the equation of the axis of symmetry is x = [tex]\frac{3}{10}[/tex]

Answer:C D E H

Step-by-step explanation:

By using the formula (Area = Length x Width) we can rearrange the equation to find the height of the rectangular poster. It comes out to be 4 feet.

To answer your question, we must use the formula for the area of a rectangle, which is Area = Length x Width. Here, the area of the poster is given as 38 square feet and the width is 9.5 feet. The length is what we're trying to find. We can set this up as an equation 38 = Length x 9.5. To find the Length, we divide both sides of the equation by 9.5 resulting in Length = 38 ÷ 9.5. Solving the equation gives us a length of approximately 4 feet. So, the 'height' of the poster would be 4 feet.

Final answer:

At age 35, Jill's IRA investment, which started with a $4,000 deposit at age 27 and earns 9.8% interest compounded monthly, will be worth approximately $8,159.55.

Explanation:

To determine the future value of Jill's IRA investment, we will use the formula for compound interest, which is A = [tex]P(1 + \(\frac{r}{n}\))^n^t[/tex], where:

P is the principal amount (the initial amount of money)

r is the annual interest rate (decimal)

n is the number of times that interest is compounded per year

t is the time the money is invested for in years

A is the amount of money accumulated after n years, including interest.

In Jill's case, she deposited $4,000 into an IRA at age 27, and we want to find out what it will be worth when she is 35. The annual interest rate is 9.8%, but since it is compounded monthly, we will have to convert this to a monthly rate and adjust the time accordingly

The steps to solve for the amount A are as follows:

Convert the annual interest rate to a decimal: 9.8% = 0.098

Find the monthly interest rate by dividing the annual rate by 12: \[tex](\frac{0.098}{12}\)[/tex]

Calculate the number of years money is invested: 35 - 27 = 8 years

Find the number of times interest is compounded: 12 months/year ×  8 years

Use the compound interest formula to calculate A.

Now, let's do the math:

P = $4,000

r = 0.098 / 12

n = 12

t = 8

A = 4000(1 + [tex]\(\frac{0.098}{12}\))^(12\(\times\)8)[/tex]

Using a calculator we get:

A = $4000(1 + 0.0081667)⁹⁶

A = $4000(1.0081667)⁹⁶

A = $4000 [tex]\(\times\)[/tex] 2.0398873

A ≈ $8,159.55

Therefore, at age 35, Jill's IRA investment will be worth approximately $8,159.55.

Answer:

(4,3)

Step-by-step explanation:

3x + 2y = 18

5x – 2y = 14

Add the two equations together to eliminate y

3x + 2y = 18

5x – 2y = 14

------------------------

8x    =   32

Divide each side by 8

8x/8 = 32/8

x = 4

Now determine the value for y

3(4) +2y = 18

12 +2y =18

Subtract 12 from each side

12-12+2y = 18-12

2y = 6

Divide by 2

2y/2 =6/2

y=3

Answer:

x=4 and y=3

Step-by-step explanation:

x+2y=18

5x−2y=14

Add these equations to eliminate y:

8x=32

Then solve8x=32for x:

8x=32

8x

8

=

32

8

(Divide both sides by 8)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

3x+2y=18

Substitute4forxin3x+2y=18:

(3)(4)+2y=18

2y+12=18(Simplify both sides of the equation)

2y+12+−12=18+−12(Add -12 to both sides)

2y=6

Answer:

60.

Step-by-step explanation:

(x^2 - 25) / (√(x + 4) - 3).

We rationalise the expression by multiplying top and bottom of the fraction by the complement of the denominator.

That is by (√(x + 4) + 3):

       (x^2 - 25)(√(x + 4) + 3)

=   ------------------------------------

     (√(x + 4) - 3)(√(x + 4) + 3)

=   (x + 5)(x - 5)(√(x + 4) + 3)

    ----------------------------------

                (x - 5)

= (x + 5)(√(x + 4) + 3).

The limit as this---> 5

is  (5 + 5)(√(5 + 4) + 3)

= 10 * 6

= 60.

Answer:

C

Step-by-step explanation:

We can solve simultaneous equations using substitution method, elimination method or graphical method. But for this purpose, we will be using the elimination method.

3x+4y=8 Equation 1

2x+y=42 Equation 2

Multiply Equation 1 by 2 and equation 2 by 3, so as to get the same coefficient for x

2(3x+4y=8)= 6x+8y=16 Equation 3

3(2x+y=42)= 6x+3y=126 Equation 4

Subtract equation 4 from 3, to eliminate x

6x-6x=0

8y-3y= 5y

16-126= -110

We now have 5y=-110

Divide both sides by 5,

y= -110/5

= -22

Substituting for y in equation 2

2x+(-22)= 42

2x= 42+22

2x=64

x= 64/2

= 32

(x, y)

(32, -22)

Step-by-step explanation:

The "points" are:

(0,96.44), (.1,97.6), (.3, 98.57), and (.6, 98.3)

The "rate of change" is the slope. This means that the change from...

0-.1 is (97.6-96.44)/.1 = 1.16/.1= 11.6

0-.3 is (98.57-96.44)/.3 = 2.13/.3 = 7.1

0-.6 is (98.3-96.44)/.6 = 1.86/.6 = 3.1

.1-.3 is (98.57-97.6)/.2 = .97/.2 = 4.85

.3-.6 is (98.3-98.57)/.3 = -.27/.3 = -.9
