Answer:

<h3>-9p²+6p+2/4p²</h3>

Step-by-step explanation:

Given the expression

(p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2)

Find the LCM

The LCM = 4p²

[p²+6p+2 - (10p²)]/4p²

Expand

p²-10p²+6p+2/4p²

-9p²+6p+2/4p²

hence the required expression is -9p²+6p+2/4p²

Solve for b in y = mx + b.
Subtract b from both sides, then subtract y from both sides.
-b = mx - y
C) mx - y = -b

Not sure how to solve this

Zigmanuir [339]

Answer:

Step-by-step explanation:

In the table, they give you an x-value. Use the x-value to solve for y. You will then get a point. Plot the points to find the graph.

y = 1/2x

y = 1/2(0)

y = 0

(0, 0)

y = 1/2x

y = 1/2(2)

y = 1

(2, 1)

y = 1/2x

y = 1/2(-4)

y = -2

(-4, -2)

Snow Dome Ski Resort has 75 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resor

Nastasia [14]

Answer:

a. See explanation for table

b. The 7th hour

Step-by-step explanation:

Given

Ski Resort

$Base\ Snow = 75in$

$Rate = 1in$ hourly

Mt. Winterpark

$Base\ Snow = 68in$

$Rate = 2in$ hourly

First, we need to illustrate the amount of snow as an equation in both cases.

$Amount = Base\ Snow + Rate * Time$

Let x be number of hours. and y be the amount of snow

So:

Ski Resort

$y= 75 + 1* x$

$y= 75 + x$

Mt. Winterpark

$y= 68 + 2 * x$

$y= 68 + 2x$

Next, we make a table to show the data.

When $x = 0$

Ski Resort: $y = 75 + 0 = 75$

Mt. Winterpark: $y = 68 + 2(0) = 68$

When $x = 1$

Ski Resort: $y = 75 + 1 = 76$

Mt. Winterpark: $y = 68 + 2(1) = 70$

When $x = 2$

Ski Resort: $y = 75 + 2 = 77$

Mt. Winterpark: $y = 68 + 2(2) = 72$

When $x = 3$

Ski Resort: $y = 75 + 3 = 78$

Mt. Winterpark: $y = 68 + 2(3) = 74$

When $x = 4$

Ski Resort: $y = 75 + 4 = 79$

Mt. Winterpark: $y = 68 + 2(4) = 76$

When $x = 5$

Ski Resort: $y = 75 + 5 = 80$

Mt. Winterpark: $y = 68 + 2(5) = 78$

When $x = 6$

Ski Resort: $y = 75 + 6 = 81$

Mt. Winterpark: $y = 68 + 2(6) = 80$

When $x = 7$

Ski Resort: $y = 75 + 7 = 82$

Mt. Winterpark: $y = 68 + 2(7) = 82$

When $x = 8$

Ski Resort: $y = 75 + 8 = 83$

Mt. Winterpark: $y = 68 + 2(8) = 84$

When $x = 9$

Ski Resort: $y = 75 + 9 = 84$

Mt. Winterpark: $y = 68 + 2(9) = 86$

When $x = 10$

Ski Resort: $y = 75 + 10 = 85$

Mt. Winterpark: $y = 68 + 2(10) = 88$

Hence, the table is:

x ---- Ski Resort ---- Mt. Winterpark

0 --------75 ----------- 68

1 --------76 ----------- 70

2 --------77 ----------- 72

3 --------78 ----------- 74

4 --------79 ----------- 76

5 --------80 ----------- 78

6 --------81 ----------- 80

7 --------82 ----------- 82

8 --------83 ----------- 84

9 --------84 ----------- 86

10 -------85 ----------- 88

(b)

From the table, the amount of snow is the same at the 7th hour and the snow is 82 inches

А support wire 12 yards long is attached to the top of a utility pole 10

stira [4]

Answer:

6.6 yd

Step-by-step explanation:

$a^{2}$ + $b^{2}$ = $c^{2}$

$10^{2}$ + $b^{2}$ = $12^{2}$ Substitute a= 10 and c=12

100+ $b^{2}$ =144 Evaluate the Powers

$b^{2}$ =44 Subtract 100 on both sides.

b= $\sqrt{44}$ Square root both sides b>0 so you dont need ⊥

b=6.6 Use a calculator to evaluate.
