-2x·-2x·(-5x·-5x+4x·4x·4x) Basically, you write out the number depending on the exponent. So if you have a power/exponent of 3, you write it out multiplied by itself 3 times. Hope this helps!

Cedric's basketball team scored fewer than 76 points in their last game. Which of the following inequalities represents the numb
Lelechka [254]

Answer: n

Step-by-step explanation:

Although you did not provide the inequalities, the only inequality that can represent the number of points Cedric's basketball team scored in their last game is the one shown below:

Let's call the number of points Cedric's basketball team scored in their last game: n.

You know that Cedric's basketball team scored fewer than 76 points in their last game. "Fewer than" means "less than", which is represented with the symbol < .

Therefore, you can represent the number of points Cedric's basketball team scored in their last game with the following inequality:

n

A plane is descending towards a runway in Chicago. The plane is flying at an altitude of 11 miles and is 193 miles from the runw
Flura [38]

The plane will make an angle 3.26^{\circ} with the runway.

Explanation:

Given that the plane is flying at an altitude of 11 miles and is 193 miles from the runway, as measured from the ground.

We need to determine the angle that the plane will make with the runway.

From the given measurements, we can see that it is a right angled triangle. Hence, let us use the tangent formula to determine the angle.

The formula for the tangent is given by

tan \ \theta=\frac{opp}{adj}

Where opp=11 and adj=193

Substituting these values in the above equation, we get,

tan \ \theta=\frac{11}{193}

Dividing, we get,

tan \ \theta=0.057

Taking tan^{-1} on both sides of the equation, we get,

\theta= tan^{-1}(0.057)

Simplifying, we have,

\theta= 3.26^{\circ}

Hence, the angle that the plane will make with the runway is 3.26^{\circ}

How do i solve z^2+9=10z
Musya8 [376]

Answer:

z = 1, z = 9

Step-by-step explanation:

Given

z² + 9 = 10z ( subtract 10z from both sides )

z² - 10z + 9 = 0

Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)

The factors are - 1 and - 9, since

- 1 × - 9 = 9 and - 1 - 9 = - 10, thus

(z - 1)(z - 9) = 0 ← in factored form

Equate each factor to zero and solve for z

z - 1 = 0 ⇒ z = 1

z - 9 = 0 ⇒ z = 9
