Answer:

complementary angles

Step-by-step explanation:

The sum of the angles is 67+23 = 90

When angles sum together to 90, the are called complementary

Answer:

Option A

Step-by-step explanation:

The measures of the two angles have a sum of 90°.

[tex]67+23=90[/tex]

Therefore, they are complementary angles, since complementary angles have a total measure of 90°.

The correct answer is: B. The initial values of the two functions are different, and the rates of change of the two functions are the same

Step-by-step explanation: Trust me

Answer: : B. The initial values of the two functions are different, and the rates of change of the two functions are the same

Step-by-step explanation: on edgenuidy

Answer:

B

Step-by-step explanation:

A)  The function in factored form is -5(x - 1)² and the vertex is (1, 0).

B)  The zeroes are x = 1, the axis of Symmetry is x = 1 and the direction of the opening is downward.

C)  The domain of the function is all real numbers and the range is

(-∞, 0].

We have,

A)

Factoring out the common factor (-5):

f(x) = -5(x² - 2x + 1)

The equation x² - 2x + 1 can be factored as (x - 1)(x - 1) or simply (x - 1)²:

f(x) = -5(x - 1)²

The equation of a quadratic function:

f(x) = a(x - h)² + k

In this case,

a = -5, h = 1, and k = 0 (since there is no constant term).

So, the vertex of the function is (h, k) = (1, 0).

B)

To find the zeros of the function, we set f(x) = 0 and solve for x:

-5(x - 1)² = 0

(x - 1)² = 0

Taking the square root of both sides:

x - 1 = 0

x = 1

The axis of symmetry is a vertical line that passes through the vertex of the parabola.

In this case, the axis of symmetry is x = 1.

The direction of the Opening:

Since the coefficient of the x² term is negative (-5), the parabola opens downward.

C)

The domain of the function f(x) is all real numbers since there are no restrictions or limitations on the possible input values of x.

The parabola opens downward and the vertex is at (1, 0), the range of the function is all real numbers less than or equal to 0.

The range can be expressed as (-∞, 0].

Thus,

A) The function in factored form: -5(x - 1)², Vertex: (1, 0).

B) Zeros: x = 1, Axis of Symmetry: x = 1, Direction of Opening: Downward.

C) Domain: All real numbers, Range: (-∞, 0].

Answer:

height of the cone = 8 ft

Step-by-step explanation:

A cone has a volume of 96π ft³. The radius of the cone is 6 ft. The height of the cone can be computed below .

The volume of a cone can be represented as follows

volume of a cone = 1/3πr²h

where

r = radius

h = height

volume of a cone = 1/3πr²h

volume = 96π ft³

r = 6 ft

h = ?

96π = 1/3 × π × 6² × h

96π = 1/3 × π × 36 × h

96π = 12πh

divide both sides by 12π

h = 96π/12π

h = 8 ft

height of the cone = 8 ft

Answer:

Step-by-step explanation:

24 is a composite number.

Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written 24 = 2³ x 3

The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 24 has exactly 8 factors.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6

Answer: $2,466.45

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:

A = P (1 + r/n) nt

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r =  Nominal Interest Rate (decimal form, 3.5/100= 0.035)

n=   number of compounding periods in each year (365)

Replacing with the values given

3,500= P (1+ 0.035/365)^365(10)

Solving for P

3,500= P (1.00009589)^3650

3,500/  (1.00009589)^3650 =P

P = $2,466.45

Answer:

Option B.

Step-by-step explanation:

The given equation of trend line is

[tex]y=\dfrac{4}{5}x[/tex]

where, x is time in minutes and y is amount of water in gallons.

It is given that the rate (gallons per minute) continues approximately.

We need to find the amount of water flow from the hose in 45 minutes.

Substitute x=45 in the given equation.

[tex]y=\dfrac{4}{5}(45)[/tex]

[tex]y=4\times 9[/tex]

[tex]y=36[/tex]

It means 36 gallons of water from hose in 45 minutes.

Therefore, the correct option is B.

Answer:

B. 12 + 2pi cm

Step-by-step explanation:

The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.

The circle's circumference can be found by using the equation c = (d)pi

The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.

Add them all together, and you get 12 + 2pi cm.

Step-by-step explanation:

Answer:

165m

Question:

Artur, Olga and Wiktor participated in the race. They started from the same place at the same time and run at constant speeds. When Artur finished the race, Olga was 15 m to the finish, and Wiktor was 35 m. When Olga finished the race, Wiktor had 22 m to the finish. At what distance was the race held?

Explanation:

Let distance be x meters

Fist statement:

Artur distance = x

Olga =x-15

Wiktor = x-35

Since they are going at constant speed, time is constant for all 3.

Their speed = distance/time

x/t, (x-15)/t, (x-35)/t respectively

Second statement:

Olga distance = x

Wiktor distance = x-22

Their Time is constant:

If it takes (x-15) in t secs,

for x meters will take = xt/(x-15)

Olga and wiktor respectively: xt/(x-15), xt/(x-15) respectively

Their speed:

Speed = distance/time

Olga = (x-15)/t,

Wiktor = (x-22)(x-15)/(xt)

Since speed is constant

Speed for Wiktor in both cases:

(x-35)/t =(x-22)(x-15)/(xt)

x(x-35) =(x-22)(x-15)

x² -35x = x² - 15x -22x +330

-35x = -37x +330

2x = 330

x = 165m

Race held at 165m distance.

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

[tex]E = 1012.50, t = 15, I = 0.045[/tex]

We have to find P. So

[tex]E = P*I*t[/tex]

[tex]1012.50 = P*15*0.045[/tex]

[tex]P = \frac{1012.50}{15*0.045}[/tex]

[tex]P = 1500[/tex]

Answer:

The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error E as such

[tex]E = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

In this question:

[tex]\sigma = 8, n = 110[/tex]. So

[tex]E = 1.96\frac{8}{\sqrt{110}} = 1.495[/tex]

The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.
