A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?

Answer:

The value of b is -3 and m is 0.

Step-by-step explanation:

You have to substitute the coordinates into both equation in order to find m and b value :

Find m,

[tex]y = mx + 3[/tex]

At (2,3),

[tex]3 = m(2) + 3[/tex]

[tex]3 - 3 = 2m[/tex]

[tex]2m = 0[/tex]

[tex]m = 0[/tex]

Find b,

[tex]y = 3x + b[/tex]

At (2,3),

[tex]3 = 3(2) + b[/tex]

[tex]b + 6 = 3[/tex]

[tex]b = 3 - 6[/tex]

[tex]b = - 3[/tex]

Answer:

b = -3

m = 0

Step-by-step explanation:

y=mx+b

Answer:

x = 36 and √x = 6; total 42 children

Step-by-step explanation:

Number of boys:  x

Number of girls:  √x

Total number of kids:  x + √x = 42.

Find x.

Rewrite x + √x = 42 as √x = 42 - x.  Then square both sides:

x = 1764 - 84x + x^2, or

x^2 - 85x + 1764 = 0

Check out Answer C:  x = 36.  Is the above equation true for x = 36?  YES

Check out Answer A:  x = 49.  Is the above equation true for x = 49?  YES

Assume that x = 36.  This would be the number of boys.  The number of girls would be √36, or 6.  Does the sum of 36 and 6 equal 42?  YES.  So the number of boys is 36 and the number of girls is 6.

Assume that x = 49.  This would be the number of boys.  The number of girls would be √49, or 8.  Does the sum of 49 and 7 equal 42?  NO.  So we reject x = 49 as the number of boys and accept x = 36 as being correct.

Answer:

It is rigid

It is isometric

The size is preserved

Step-by-step explanation:

Given that Triangle ABC was translated to form A'B'C', then both triangles are congruent triangles.

A translation only moves the figure, preserving the size.

Because the size is preserved, it is a rigid transformation or isometric transformation.

Step-by-step explanation:

There is no option to choose from, but the knowledge of what irrational numbers are, would help cover this cost.

A rational number is a number that can be written as a simple fraction, a/b. Examples are 1/2, 5/6,...

If a number cannot be written as a simple fraction, then it is called irrational.

Answer:

the first and last option.

Step-by-step explanation:

the equation will be equal to 288.

x is the amount of one payment that he makes 3 times, hence the 3x.

15 is his initial payment so that is added to the 3x to equal 288.

the second equation still equals to 288.

the 15 is still there because added to the phone price it is equal to 288.

the x represents the price of the phones and 3 is how many he's getting, hence the 3x.

Answer:

  D.  16.8 years

Step-by-step explanation:

The multiplier each year is 1-3% = 0.97, so the multiplier after x years is 0.97^x. You want to know the value of x when that multiplier is 60%, or 0.60.

  0.97^x = 0.60

  x·log(0.97) = log(0.60) . . . . . . take logarithms

  x = log(0.60)/log(0.97) ≈ 16.8

At the given rate, it will be 16.8 years before 60% of the species remains.

[tex]3\sqrt{6} = \sqrt{9}*\sqrt{6} = \sqrt{9*6} = \sqrt{54}[/tex]

The rule I'm using is

[tex]\sqrt{x}*\sqrt{y} = \sqrt{x*y}[/tex]

note how I rewrote "3" into the square root of 9, so that everything would have a square root over it, and that allows me to use that rule above.

[tex]\sqrt{54}[/tex] equivalent to the expression [tex]3\sqrt{6}[/tex].

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given expression

[tex]3\sqrt{6}[/tex]

We have the property [tex]\sqrt{x}[/tex] × [tex]\sqrt{y}[/tex] = [tex]\sqrt{x.(y)}[/tex]

[tex]3\sqrt{6}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{6}[/tex]

= [tex]\sqrt{9.(6)}[/tex]

= [tex]\sqrt{54}[/tex]

[tex]\sqrt{54}[/tex] equivalent to the expression [tex]3\sqrt{6}[/tex].

Answer:

Step-by-step explanation:

For this case we have a function of the form:

f (x) = 4 ^ x-6

We want to move the graph five units up.

Therefore, the new function is given by:

g (x) = f (x) +5

Substituting we have:

g (x) = 4 ^ x-6 + 5

Rewriting the function:

g (x) = 4 ^ x-1

Answer:

The new function is given by:

g (x) = 4 ^ x-1

option C

Click to let other

The function g which is created by shifting the graph of function f up 5 units is given by [tex]g(x) = 4^x - 1.[/tex]

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To shift the graph of function f up 5 units, we need to add 5 to the output (y-value) of the function.

Therefore, the function g(x) will be:

g(x) = f(x) + 5

Substituting the expression for f(x), we get:

[tex]g(x) = 4^x - 6 + 5\\g(x) = 4^x - 1[/tex]

Therefore,

The function g which is created by shifting the graph of function f up 5 units is given by [tex]g(x) = 4^x - 1.[/tex]

Answer:

8

Step-by-step explanation:

because we know its an isosceles triangle angle A and C will both be the same and since we know A = 69 C will also be 69. we also know that angles in a triangle add to 180 so take away the two 69s from the 180 to get 42

then we work backwards if its 5x + 2 then we need to do 5x - 2 to get 40 then divide it by 5 to get your answer 8!

(sorry if the explanation doesnt make sense )

Answer:

Correct option: first one.

Step-by-step explanation:

Let's analyse each option:

1)

When f = 0, |0 + 3| < 9, which is true because 3 is less than 9.

This statement is true, and the value f = 0 in inside the solution graphed by Sarah.

2)

When f = -12, |-12 + 3| < 9, which is true because 9 is equal to 9.

This statement is false, because the inequality uses a "less-than" symbol and not a "equal" symbol, so 9 < 9  is false

3)

When f = 10, |10 + 3| < 9, which is true because 9 is greater than 13.

This statement is false, because 9 is not greater than 13.

4)

When f = -14, |-14 + 3| < 9, which is true because 9 is greater than –11.

This statement is false, because the value of |-14 + 3| is 11 and not -11.

So the correct option is the first one.

Answer:

30%

Step-by-step explanation:

18 / 60 = .3 * 100 = 30%

Answer:

The percent of the the corn seeds is 30%.

Step-by-step explanation:

Because when you calculate 60% and 18% will get a percent 30%.

Solution for 18 is what percent of 60:

18:60*100 =

( 18*100):60 =

1800:60 = 30

Now we have: 18 is what percent of 60 = 30

Question: 18 is what percent of 60?

Percentage solution with steps:

Step 1: We make the assumption that 60 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=60$.

Step 4: In the same vein, $x\%=18$.

Step 5: This gives us a pair of simple equations:

$100\%=60(1)$.

$x\%=18(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{60}{18}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{18}{60}$

$\Rightarrow x=30\%$

Therefore, $18$ is $30\%$ of $60$.

Answer:

x = -6.

Step-by-step explanation:

5 -2x = -4x - 7

Add '4x' to both sides:

5 - 2x + 4x + -4x + 4x -7

5 + 2x = -7

Subtract '5' from both sides:

5 - 5 + 2x = -7 - 5

2x = -12

Divide both sides by '2':

x = -6.

Answer:

19%

Step-by-step explanation:

1. Decrease by 10% = 0.9 times

2. Repeat decrease by 10% = 0.9*0.9= 0.81 times

0.81 times decrease equals to 100%-81%= 19% decrease
