mn + p = 2
Solve for m
Answers
Answer:
m = [tex]\frac{2-p}{n}[/tex]
Step-by-step explanation:
Given
mn + p = 2 ( subtract 2 from both sides )
mn = 2 - p ( isolate m by dividing both sides by n )
m = [tex]\frac{2-p}{n}[/tex]
Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month?
Answers
Answer:
$840
Step-by-step explanation:
price of 1 vacuum cleaner = $150
total no . of vacuum cleaner sole = 70
thus,
price of 70 vacuum cleaner sold = 70*price of 1 vacuum cleaner
price of 70 vacuum cleaner sold = 70*$150 = $10,500
commission of Alonzo = 8% of total vacuum cleaner sold
commission of Alonzo = 8% of $10,500
commission of Alonzo = 8 /100 * $10,500 = $840
Thus, Alonzo made $840 in past month

Choose a justification for each step in the derivation of the sine difference identity.
Answers
Answer:
Step-by-step explanation:
The missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even and sine function is odd respectively.
Given:
The given expression is [tex]\sin (x-y)[/tex].
To find:
The justification for each step.
Explanation:
Cofunction identities:
[tex]\sin\left(\dfrac{\pi}{2}-x\right)=\cos x[/tex]
[tex]\cos\left(\dfrac{\pi}{2}-x\right)=\sin x[/tex]
Cosine difference identity:
[tex]\cos(x-y)=\cos x\cos y+\sin x\sin y[/tex]
Cosine function is even, so [tex]\cos(-x)=\cos x[/tex].
Sine function is odd, so [tex]\sin(-x)=-\sin x[/tex].
We have,
[tex]\sin (x-y)[/tex]
[tex]=\cos\left|\dfrac{\pi}{2}-(x-y)\right|[/tex] Step 1: Cofunction identity
[tex]=\cos\left|\dfrac{\pi}{2}-x+y\right|[/tex] Step 2: Distributive property
[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)+y\right|[/tex] Step 3: Associative property
[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)-(-y)\right|[/tex] Step 4: Factoring out
[tex]=\cos\left(\dfrac{\pi}{2}-x\right)\cos(-y)+\sin\left(\dfrac{\pi}{2}-x\right)\sin(-y)[/tex] Step 5: Cosine difference identity
[tex]=\sin(x)\cos(-y)+\cos(x)\sin(-y)[/tex] Step 6: Cofunction identity
[tex]=\sin(x)\cos(y)-\cos(x)\sin(y)[/tex] Step 7: Cosine function is even, sine function is odd
Therefore, the missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even, sine function is odd respectively.

(show work too please)
Answers
Answer:
x = -12
Step-by-step explanation:
x-2(x+1)+3(x+2) = x-4 (equation)
x-2x+2+3x+6 = x-4 (simplify)
2x+8 = x-4 (combine like terms)
x+8 = -4 (subtract x from both sides)
x = -12 (subtract 8 from both sides)

Point Ris on line segment QS. Given QR = 3x – 8, QS = 3x, and
RS = 2x, determine the numerical length of RS.
Answer: RS
Submit Answer
attempt 1 out of 2
Answers
Answer:
RS = 8
Step-by-step explanation:
Given that R is on QS , then
QR + RS = QS , substitute values
3x - 8 + 2x = 3x , that is
5x - 8 = 3x ( subtract 3x from both sides )
2x - 8 = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus
RS = 2x = 2 × 4 = 8

A circular pool has an area of approximately 154 square feet. To the nearest foot, how much fencing is needed to completely surround the pool?
Answers
Given parameters:
Area of pool = 154ft²
Unknown:
The circumference or perimeter of the pool = ?
Solution:
The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.
To solve this problem, we need to find the radius from the given area.
Area of a circle = π r²
154 = π r²
r² = [tex]\frac{154}{3.142}[/tex] = 49
r = 7ft
Now the circumference of a circle = 2 π r
= 2 x π x 7
= 44ft
The circumference of the circle is 44ft
