Help please! Due tonight! Solve the quadratic equation for x. 4x2+8x=0

andreev551 [17]

Answer 1: $x=0$

Answer 2: $x=-2$

Note: BOTH of those answers are correct. Chose either one.

Factor left side of equation

$4x(x+2)=0$

Set factors equal to 0

$4x=0--------->x+2=0\\x=0---------->x=-2$

Least to greatest was she write and why ❓

oksano4ka [1.4K]

She is wrong because -2 1/3 is smaller than -1.4. The bigger the negative number is, the smaller it is.

If a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will

DochEvi [55]

Answer:

Option A is correct

Step-by-step explanation:

The given equation is

h = -16t^2+6t+4

When the ball will hit the ground, height h = 0

Putting value of h = 0

0 = -16t^2+6t+4

Now solving to find the value of t

=> -16t^2+6t+4 = 0

Multiply with -1

16t^2-6t-4=0

Using quadratic formula to find value of t

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

a= 16, b= -6 and c= -4

Putting values,

$t=\frac{-(-6)\pm\sqrt{(-6)^2-4(16)(-4)}}{2(16)}\\t=\frac{6\pm\sqrt{36+256}}{32}\\t=\frac{6\pm\sqrt{292}}{32}\\t=\frac{6\pm17.08}{32}\\t=\frac{6+17.08}{32} \,\,and\,\, t=\frac{6-17.08}{32}\\t=0.721\,\,and\,\, t=-0.34$

Since time cannot be negative, so t = 0.721 or 0.72

So, Option A is correct

1.If a number is chosen at random from the integers 5 to 25 inclusive , find the probability that the number is a multiple of 5

Drupady [299]

I'll do problem 1 to get you started.

set A = multiples of 3 between 5 and 25 = {6, 9, 12, 15, 18, 21, 24}

there are 7 items in set A, so we can say n(A) = 7

set B = multiples of 5 between 5 and 25 = {5,10,15,20,25}

Here we have n(B) = 5

set C = multiples of 3 and 5, between 5 and 25 = {15}

n(C) = 1 which we can rewrite as n(A and B) = 1.

-----------------------------------------

To summarize so far,

n(A) = 7
n(B) = 5
n(A and B) = 1

From those three facts, then we can say,

n(A or B) = n(A) + n(B) - n(A and B)

n(A or B) = 7 + 5 - 1

n(A or B) = 11

There are 11 values between 5 and 25 that are multiples of 5, multiples of 3, or both.

Those 11 values are: {5, 6, 9, 10, 12, 15, 18, 20, 21, 24, 25}

This is out of 25-5+1 = 21 values overall which are in the set {5,6,7,...,24,25}

So we have 11 values we want out of 21 overall, which leads to the probability 11/21

Final Answer: 11/21
