In the formula a2 + b2 = c2, what is the value of a2?

Answers

Answer 1

Answer: a^2 + b^2 = c^2 Moving b^2 to RHS a^2 = c^2 - b^2

Answer 2

Answer: $a^2+b^2=c^2\ \ \ \ |subtract\ b^2\ from\ both\ sides\n\na^2=c^2-b^2\n\n\boxed{a=√(c^2-b^2)}$

Jasmine is building birdhouses. it takes her 3 1/2 hours to build 4 birdhouses. which of the following is a equivalent rate?a. 14 hours to build 18 birdhouses
b. 28 hours to build 35 birdhouses
c. 7 hours to build 8 birdhouses
d. 21 hours to build 28 birdhouses

plz help quick

Option C: 7 hours to build 8 house,

Whenever getting work-time related questions, it is needed to focus that as the amount of work done increases, the time needed to complete also increases.

Given that:

3.5 hours of work is needed to build 4 birdhouses.

Thus as we increase the time twice, the number of birdhouses build by the same person Jasmine will be twice as she got doubletime, thus building 2 times 4 i.e. 8 birdhouses.

Thus we have:

Jasmine takes 7 hours of work to build 8 birdhouses.

Therefore we see that Option C: 7 hours to build 8 birdhouses is correct.

How do I write the equations of lines through the given point parallel to the given line and perpendicular to the given line?

Answers

first we find the slope of the original equation
4x - 2y = 3
-2y = -4x + 3
y = -4/-2x - 3/2
y = 2x - 3/2......slope here is 2

for a parallel line, we use the same slope
y = mx + b
slope(m) = 2
(2,1)...x = 2 and y = 1
now we sub and find b, the y int
1 = 2(2) + b
1 = 4 + b
1 - 4 = b
-3 = b
so ur parallel equation is : y = 2x - 3

for a perpendicular slope, we need the negative reciprocal. All that means is flip the slope and change the sign. So we have a slope of 2...the negative reciprocal we need is -1/2
y = mx + b
slope(m) = -1/2
(2,1)...x = 2 and y = 1
now we sub again
1 = -1/2(2) + b
1 = -1 + b
1 + 1 = b
2 = b
ur perpendicular line is : y = -1/2x + 2
=========================
x + 4 = 0
x = -4....this is a vertical line with an undefined slope....sorry but I am not sure about this one

Two students were asked to use estimation strategies to find a reasonable solution to this question: Darrell has $1,990 saved and wants to buy a motorcycle. He earns $10 per hour and he works for 39 hours. Estimate how much money, Darrell has left after buying a $2,200 motorcycle. From the choices below, select the student with a more reasonable solution.

Answers

Answer:

1990+(10h)-2200

1990+(10x39)-2200

Step-by-step explanation:

he already has 1990

He earns $10 per hour

he works for 39 hours

$2,200 needed for a motorcycle

1990+(10h)-2200

1990+(10x39)-2200
