Brody created a map of his neighborhood using a scale of 2 inches = 3 blocks. If his street is 9 blocks long, how long will it be on the map?

Answers

Answer:

6 inches

Step-by-step explanation:

If 3 blocks equals 2 inches, then we must first find out how many times 3 can fit into 9. We do this by dividing 9 by 3 to get 3. To get your final answer just multiply 2 by 3 and you will get 6 inchs. I hope this helped :0

D) LM=12; QP=8

Step-by-step explanation:

12/18=(x-1)/(x+3)

cross multiply

12x+36=18x-18

36+18=18x-12x

Answers

Answer:

Step-by-step explanation:

Sin(35) = opposite / hypotenuse

Sin(35) = 4 / hypotenuse Multiply both sides by the hypotenuse

hypotenuse * sin(35) = 4 Divide by Sin(35)

hypotenuse = 4/Sin(35)

Sin(35) = 0.5736

hypotenuse = 4/0.5736

hypotenuse = 6.9737

Consider the functions k(x) = x + 1, m(x) = x - 4, n(x) = x + 5, and f(x) = k(x) • m(x) · n(x). a. Determine the degree of the function f(x).

Answers

Answer:

[tex]Degree = 3[/tex]

Step-by-step explanation:

Given

[tex]k(x) = x + 1[/tex]

[tex]m(x) = x - 4[/tex]

[tex]n(x) = x + 5[/tex]

[tex]f(x) = k(x) * m(x) * n(x)[/tex]

Required

The degree of f(x)

First, calculate f(x)

[tex]f(x) = k(x) * m(x) * n(x)[/tex]

[tex]f(x) = (x +1) * (x - 4) * (x + 5)[/tex]

Expand

[tex]f(x) = (x +1) * (x^2 - 4x + 5x - 20)[/tex]

[tex]f(x) = (x +1) * (x^2 + x - 20)[/tex]

Further Expand

[tex]f(x) = x^3 + x^2 - 20x +x^2 + x - 20[/tex]

Collect like terms

[tex]f(x) = x^3 + x^2 +x^2 - 20x + x - 20[/tex]

[tex]f(x) = x^3 + 2x^2 - 19x- 20[/tex]

The degree of f(x) is the highest power of x.

Hence:

[tex]Degree = 3[/tex]

If the friends start seesawing with the plank in a level position, how long does it take for the friend in the left seat to move upward, downward,
and then back to the initial position?

Answers

Answer:

I believe it would be 4 seconds

Step-by-step explanation:

PLATO/Edmentum

The time it takes for the friend in the left seat to move upward, downward, and then back to the initial position is 4 seconds.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Two friends are sitting on a seesaw at the park. The height, h(t), of the left seat, in inches above the ground, is modeled by a sine function.

Let t represent the time, in seconds, since the friends started seesawing.

t 0 1 2 3 4 5 6h(t) 24 48 24 0 24 48 24

The friends start seesawing with the plank in a level position. The initial position at 0 of them is at 24.

The group has to come back to this position after moving upward and downward. The time it takes to reach upward is,

[tex]f(48)=t_{up}\\f(48)=1[/tex]

The time it takes to reach downward after going upward is,

[tex]f(0)=t_{down}\\f(0)=3[/tex]

Coming back to initial potion,

[tex]f(24)=t_{i}\\f(24)=4[/tex]

Thus, the time it takes for the friend in the left seat to move upward, downward, and then back to the initial position is 4 seconds.

Solve for X. Assume that segments that appear to be tangent are tangent Round to the nearest tenth as necessary.

Answers

9514 1404 393

Answer:

11.1

Step-by-step explanation:

The tangent makes a right angle with the diameter at the point of tangency. So, the triangle is a right triangle, and the Pythagorean theorem can be used to find the length of x. The radius is shown as 7.1, so the diameter will be 14.2.

x^2 + 14.2^2 = 18^2

x^2 = 122.36

x = √122.36 ≈ 11.1

The length of the tangent is about 11.1 units.

Find the sum of the first 20 terms of the sequence {4,10,16,22,...} step by step

Answers

Answer:

All terms separated by 6 so #20 = 4 + 6 * 19 = 118

(if the first term were 6 instead of 4 the 20th would be 120)

Also, #10 = 58 and #11 = 64 (you can use the same reasoning)

The 1st and 20th term add to 4 + 118 = 122

The 2nd and 19th add to 10 + 112 = 122

Likewise 10th and 11th add to 58 + 64 = 122

So 10 * 122 = 1220
