Answer:

25 and 65

Step-by-step explanation:

Let one of the angles be x.

So, the other angle is 15 + 2x

complementary angles add up to 90 degrees.

so, we have

x + 2x + 15 = 90

3x + 15 = 90

Subtract 15 from both sides

3x = 75

solve for x

x = 25

so, the angles are 25 and 65

2 complementary angles sum up to 90°.

Take one angle as 'x'. Then, the other angle will be '15 + 2x'.

15 + 2x + x = 90°

15 + 3x = 90°

3x = 90 - 15

3x = 75

x = 75/3

x = 25°.

Measure of 1st angle (x°) = 25°

Measure of 2nd angle (15 + 2x°) = 15 + 2*25 = 65°.

=》 The 2 complementary angles are 25° & 65°.

Answer:

f(-9) = 86

Step-by-step explanation:

Hi there!

f(x) = x² + 5

To find f(-9), replace x with -9:

f(-9) = (-9)² + 5

f(-9) = 81 + 5

f(-9) = 86

The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

An exponential growth is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b > 1

Let y represent the bacteria population after t minutes

Given that initially has 2 million bacteria, hence:

a = 2 million = 2000000

It increases at a rate of 3.5% every minute, hence:

b = 100% + 3.5% = 1.035

The equation is:

[tex]y=2000000(1.035)^t[/tex]

Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

Step-by-step explanation:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Answer:

44 Feet

Step-by-step explanation:

Trust me

Answer:

Width = 43 feet

Step-by-step explanation:

Given the 188-feet perimeter of a rectangular garden, for which its length is 8 feet longer than its width:

We can express the length of the rectangular garden as: 8 + W.

Hence, in order to solve for the length and the width of the rectangular garden, use the following formula for the perimeter of a rectangle:

Perimeter (P) = 2(L + W) or 2L + 2W = 188 feet

Length (L) = 8 + W

Width (W) = W

Substitute these values into the perimeter formula to solve for the value of the rectangular garden's dimensions:

P = 2L + 2W

188 feet = 2(8 + W) + 2W

Distribute 2 into the parenthesis, (8 + W):

188 = 16 + 2W + 2W

Combine like terms:

188 = 16 + 4W

Subtract 16 from both sides:

188 - 16 = 16 - 16 + 4W

172 = 4W

Divide both sides by 4 to solve for W:

[tex]\LARGE\mathsf{\frac{172}{4}\:=\:\frac{4W}{4}}[/tex]

W = 43

Therefore, the width of a rectangular garden is 43 feet.  

Since we determined that the length is 8 + W, then it means that the length of the rectangular garden is 51 feet.

Double-check whether we have the correct dimensions for the rectangular garden by substituting the length (L) = 51 feet, and the width (W) = 43 feet, into the perimeter formula:

P = 2L + 2W

188 feet = 2(51) + 2(43)

188 feet = 102 + 86

188 feet = 188 feet  (True statement). This means that we have the correct dimensions for the rectangular garden.

Therefore, the width of a rectangular garden is 43 feet.  

Answer:

Step-by-step explanation:

Justice needs $72 to fence in his garden.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Justice needs 24 feet of fencing to surround his garden.

The fencing is priced at $0.25 per inch.

Since, 1 foot = 12 inch

Hence, 24 feet = 24 x 12 inch = 288 inch.

Cost of the fencing in one inch = $0.25

So, Cost of the fencing in 288 inch = 288 x 0.25

                                                      = $72

Thus, Justice needs $72 to fence in his garden.

Graph 3 - The x y-coordinate plane is given. The curve enters the window at the approximate point (−10, −3.2), goes up and right becoming less steep, crosses the y-axis at y = −1, and exits the window just below the x-axis.

g(x) = 2x^2

for g(- 4), you just plug in - 4 for x

g(- 4) = 2(- 4)^2

g(- 4) = 2(16)

g(- 4) = 32

Answer:

g(-4) = 32

Step-by-step explanation:

Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.

g(x) = 2x²

g(-4) = 2(-4)² = 2(-4)(-4)

g(-4) = 2(16)  

g(-4) = 32

Therefore, g(-4) = 32.
