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 3.90 miles per minute

Step-by-step explanation:

I'll do 2.

Alright,Alex let say we have factored a quadratic into two binomial, for example

$(5x + 3)(6x - 4)$

If we set both of those equal to zero

$(5x + 3)(6x + 4) = 0$

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

$if \: ab = 0 \: then \: a = 0 \: and \: b = 0$

This means we set each binomal equal to zero to find it root.

$5x + 3 = 0$

$5x = - 3$

$x = - \frac{3}{5}$

$6x + 4 = 0$

$6x = - 4$

$x = - \frac{2}{3}$

So our roots are negative 3/5 and negative 2/3 using zero product property

Answer:

just sub in the numbers into the equation to replace the X ..

example for

a) h(7) : 44

Step-by-step explanation:

h(7) : x^2 -5

sub in 7 into the equation to replace X

so you get

(7)^2 - 5

Dante plans to put 80% of his paycheck into a savings ccount and spend the other 20%. His paycheck this week was $295. About how

Anni [7]

The 20% statement is useless

80% of $295 is what?
80%×295=??
.80 × 295 = $236.00 in savings
