Answer:

A: Not rational, because a rational number is any integer, fraction, terminating decimal, or repeating decimal. This does not show that.

B: In between 13 and 15, (200 rooted is 14.1) I know this because if you simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

C: He should make each side about 3.76 feet long. Because, 3.76^4 is 200, therefore it would become 200 square feet if each side is 3.76 feet long.

What two number multiplied equal 12 but also added together equal -7

FromTheMoon [43]

A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3

Please help !!!!! Explain to me and need answer quick

schepotkina [342]

Answer:

We can see that the denominators of both the numbers is not same

So in order to make it same for the both numbers, we will multiply the second number by 2/2 ,(which is basically 1 so it won't affect our calculations)

$\frac{11}{2^2 * 5^2}$ - $\frac{2}{2^2 * 5^2}$

So we will just subtract the numbers now

$\frac{9}{2^2 * 5^2}$ This is the answer

The number y of deer in a county after x years can be modeled by y=0.75x^2 + 10.5x + 1300. When were there about 2000 deer? Roun

Lemur [1.5K]

Answer:

24 years

Step-by-step explanation:

We are told that the model of number of deers is;

y = 0.75x² + 10.5x + 1300

Where;

y represents number of deers

x represents number of years

Now, we want to find how many years it will take to get to 2000 deers.

Thus;

2000 = 0.75x² + 10.5x + 1300

0.75x² + 10.5x + 1300 - 2000 = 0

0.75x² + 10.5x - 700 = 0

Using quadratic formula, we have;

x = [-b ± √(b² - 4ac)]/2a

x = [-10.5 ± √(10.5²- (4*0.75*-700)]/(2*0.75)

x = [-10.5 ± √(110.25 + 2100)]/(1.5)

x = [-10.5 ± √2210.25]/(1.5)

x ≈ -38 or 24

Number of years can't be negative, so we will take the positive value.

So, x = 24 years
