A missile is fired at an angle of 75 from the horizontal. At one point, its speed was 900 mph. Find its horizontal velocity in m

Hello Chrisd117991999.

If the missile was going 900mph and we are trying to find the horizontal velocity

This could be 3.88, and rounding it to the nearest hundredth would be <u><em>3.90 miles per minute</em></u>

There are 10 marbles in the bag. There are two purple marbles, 3 red marbles and 5 yellow marbles. You will pick a marble three

Evgen [1.6K]

Answer:

30/1000

Step-by-step explanation:

red has a chance of 3/10

purple has a chance of 2/10

yellow has a chance of 5/10

for probability, multiply the denominators together, and the numerators together

3*2*5 = 30

10*10*10 = 1000

So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000

Hope this helps!

Answer:

Part 1) The domain of the quadratic function is the interval (-∞,∞)

Part 2) The range is the interval (-∞,1]

Step-by-step explanation:

we have

$f(x)=-x^2+14x-48$

This is a quadratic equation (vertical parabola) open downward (the leading coefficient is negative)

step 1

Find the domain

The domain of a function is the set of all possible values of x

The domain of the quadratic function is the interval

(-∞,∞)

All real numbers

step 2

Find the range

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

we have a vertical parabola open downward

The vertex is a maximum

Let

(h,k) the vertex of the parabola

The range is the interval

(-∞,k]

Find the vertex

$f(x)=-x^2+14x-48$

Factor -1 the leading coefficient

$f(x)=-(x^2-14x)-48$

Complete the square

$f(x)=-(x^2-14x+49)-48+49$

$f(x)=-(x^2-14x+49)+1$

Rewrite as perfect squares

$f(x)=-(x-7)^2+1$

The vertex is the point (7,1)

therefore

The range is the interval

(-∞,1]
