Identify an equation in point-slope form for the line perpendicular to y = -1/2x + 11 that passes through (4, -8)
Answer:
y+8 = 2(x-4)
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.
And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:
y-y1 = m(x-x1)

The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

Work out the volume of this prism.
Answer:
480 cm³
Step-by-step explanation:
Giveb that :
Area = 40cm²
Height, h = 12 cm
The volume of a prism is the product of it's base area and height, h
Base area = 40cm² ; height = 12cm
Volume = base area * height
Volume = 40cm² * 12cm
Volume = 480cm³

a family buys 5 airline tickets online. the family buys travel insurance that costs $18 per ticket. the total cost is $955. let z represent the price of one ticket. write an equation for the total cost. then find the price of one ticket.
Answer: Equation that represents this situation is 5(x+17) = 1495,
Price of one ticket is 282
Step-by-step explanation:
Here x represents the price of one ticket,
Also, a person bought travel insurance that costs $17 per ticket.
Hence, the total cost of a person = x + 17
⇒ The total cost of 5 person = 5 ( x + 17 )
But, According to the question,
5 ( x + 17 ) = 1495
⇒ x + 17 = 299
⇒ x = 299 - 17
⇒ x = 282

Cedro bought 10 ounces of Cereal A for $2.25. Then he bought 15 ounces of Cereal B for $3.30. Which cereal is less expensive?
Answer:
Cereal B.
Step-by-step explanation:
To figure out how much it costs per ounce for each cereal, first we need to divide.
Cereal A: $2.25 / 10 = $.225 per ounce
Cereal B: $3.30 / 15 = $.22 per ounce
So, cereal B is less expensive.

solve (5w-8)/3 = 4w + 2[
Answer:
w = -2
Step-by-step explanation:
(5w - 8)/3 = 4w + 2
First, we will distribute the division problem on the left.
5w/3 - 8/3 = 4w + 2
Next, subtract 4w from both sides
5w/3 - 8/3 - 4w = 4w + 2 - 4w
We have to turn 4w on the left side into a fraction, but we have to make sure they are like fractions (meaning they have the same denominator).
5w/3 - 8/3 - 12w/3 = 2
5w/3 and -12w/3 are like terms (same variables) so we will subtract -12w/3 from 5w/3
-7w/3 - 8/3 = 2
Now, we will add 8/3 to both sides
-7w/3 - 8/3 + 8/3 = 2 + 8/3
to add 2 and 8/3 together, we need to make them like fractions
-7w/3 = 6/3 + 8/3
-7w/3 = 14/3
Now we get rid of the 3 by mutliplying 3 to both sides
3 * (-7w/3) = 3 * (14/3)
-7w = 14
No we have to divide -7 to both sides
-7w/-7 = 14/-7
w = -2
