Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of the ladder from the base of the house? Leave the answer as a simplified square root.

Answers

Answer 1

Answer:

[tex]3 \sqrt{11} [/tex]

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

[tex] {a}^{2} + {b}^{2} = c {}^{2} [/tex]

where a and b are the legs and c is the hypotenuse l.

Let plug it in

[tex] {a}^{2} + 15 {}^{2} = {18}^{2} [/tex]

[tex] {a }^{2} + 225 = 324[/tex]

[tex] {a}^{2} = 99[/tex]

[tex]a = \sqrt{99} [/tex]

[tex]a = \sqrt{9 \times 11} [/tex]

[tex]a = 3 \sqrt{11} [/tex]

On the windowsill is a plant that is 10 inches tall. It is growing 3 inches per
week. A second plant, which is 17 inches tall, is on the coffee table. It is
growing 2 inches per week. Eventually the two plants will be the same
height. How tall will the plants be? How many weeks will that take? *

Answers

Answer:18 days

Step-by-step explanation:

Here's a short table of heights:

 day 0: height = 1

 day 1: height = 1 + (1/2)(1) = 3/2

 day 2: height = (3/2) + (1/3)(3/2) = 3/2 + 1/2 = 2

The pattern of heights is ...

 (day, height) = (0, 1), (1, 1.5), (2, 2)

The plant is growing 1/2 its original height each day, so we can write the equation ...

 h = 1 + d/2

We want to find the number of days (d) that result in a height of 10 (ten times the original height).

 10 = 1 + d/2

 9 = d/2 . . . . subtract 1

 18 = d . . . . . multiply by 2

It took 18 days for the plant to grow to 10 times its original height.

Answer:

it would take 9 weeks for both of the plants to equally meet the same height which is 33 inches

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.

x = ±3
x = 3
x = -3
x = ±9

2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.

h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)

Answers

Answer:

Part 1)

A

Part 2)

C

Step-by-step explanation:

1)

We are given:

[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]

And that:

[tex]h(x)=f(x)/g(x)[/tex]

And we want to now for which values of x is h(x) undefined.

So, by substitution:

[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

[tex]x^2-9=0[/tex]

Add 9 to both sides:

[tex]x^2=9[/tex]

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

[tex]x=\pm 3[/tex]

So, h(x) is undefined for ±3.

Our answer is A.

2)

We are given:

[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]

And we want to find:

[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]

So:

[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]

Distribute:

[tex]h(x)=3^x-3^{2x}+3^x[/tex]

Combine like terms:

[tex]h(x)=2(3^x)-3^{2x}[/tex]

Rewrite:

[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]

Factor out:

[tex]h(x)=3^x(2-3^x)[/tex]

So, our answer is C.

Answers

Answer:

A man has a body mass of mkg he is 30kg heavier than each of his children. Express the body mass of each child in terms of m if the mass of the father and children sum up to 156kg find the mass of the father

The mass of the father would be 72 kg.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A man has a body mass of m kg. He is 30 kg heavier than each of his twin children.

Let the mass of first child be x

x = m - 30

Let the mass of second child be y

y =  m - 30

The total mass of the two children and a father would be

m + x + y = 156

Substitute;

m + m - 30+ m - 30= 156

3m - 60  = 156

3m = 156 + 60

m = 216 / 3

m = 72.

So the mass of the father would be 72 kg.

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?​

Answers

Answer:monthly rent of a 1-bedroom apartment= $280

Step-by-step explanation:

Let the  cost of 1 bed room apartment = x

And the cost of two bedroom apartment= 2x-40

Since the cost of of two bedroom apartment = $520  

Then the cost of one bed room part will be expressed as

520= 2x- 40

520+40 = 2x

560= 2x

x= 560/ 2

x= 280

Therefore the  cost of 1 bed room apartment = x= $280
