Determine whether the forces in the pair are pulling at right angles to each other.

prohojiy [21]

Answer:

C) 3.0

Step-by-step explanation:

Let the length of the other side be x.

Using Pythagoras theorem for right-angled triangle,

4.2^2=2.9^2+x^2

or,x^2=4.2^2-2.9^2

or,x^2=9.23

or,x=√9.23=3.0 units

If you know the names of the remaining nine students in the spelling bee, what is the probability of randomly selecting an orde

rjkz [21]

The probability of getting the correct order in the spelling bee is 1 chance in 362,880.

This is a permutation problem. Our goals is to find the total number of ways that the 9 students can be ordered.

For the first spot there are 9 choices, then 8 choices, then 7 choices....

We need to evaluate:
9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 362,880

Another way to write this is: 9!

a bill to landscape your yard is $720. the material cost $375 and the labor is $34.50 per hour . Write and solve an equation to

Tom [10]

Answer: 10 hours

Explanation:

Bill = $720

Material = $375

Labour = $34.50x

375 + 34.5x = 720

34.5x = 345

x =10

F(x) = 49 − x2 from x = 1 to x = 7; 4 subintervals

Setler [38]

Answe

Given,

f(x) = 49 − x² from x = 1 to x = 7

n = 4

$\Delta x = \dfrac{7-1}{4}= 1.5$

For x= 1

f(x₀) = 49 - 1^2 = 48

x = 2.5

f(x₁) = 42.75

x = 4

f(x₂) = 49 - 4^2 = 33

x = 5.5

f(x₃) = 49 - 5.5^2 = 18.75

x = 7

f(x₄) = 49 - 7^2 = 0

We have to evaluate the function on therigh hand point

$A = \Delta x [f(x_1)+f(x_2)+f(x_3)+f(x_4)]$

$A = 1.5 [42.75+33+18.75+0]$

$A = 141.75$

For Area for left hand sum

$A = \Delta x [f(x_0)+f(x_1)+f(x_2)+f(x_3)]$

$A = 1.5 [48+42.75+33+18.75]$

$A =213.75$
