Review The Following Information About Vectors Q And R.q = 4, 1r = A, 37(q + R) = 35, 28What Is The Value
Answer 2

Vector addition is done by addition of the components

The value of a is -1

a = –1

Reason:

The given parameters are;

q = <-4, 1>

r = <a, 3>

7·(q + r) = <-35, 28>

Required:

The value of a

Solution;

By vector addition of the components of q, and r, we have;

q + r = <-4 + a, 1 + 3> = <-4 + a, 4>

q + r =  <(-4 + a),    4>

By plugging in the value of q + r from the above step, we have;

7·(q + r) = <7 ×(-4 + a), 7 × 4> distribution property

7·(q + r)  = <-35, 28> Given

Therefore, by comparison of components, we have;

7 ×(-4 + a) = -35

[tex]-4 + a = -\dfrac{35}{7} = -5[/tex]

a = -5 + 4 = -1

a = –1

The correct option for the value of a is –1

What is the value of the expression (x+y) + 5 if x = 6 and y =4


Answers

Answer:

15

Step-by-step explanation:

the expression is (x+y)+5

Now, you need to plug in x=6 and y=4.

So, you have the expression, (6+4)+5

You then add the 6 and 4 since they are in parenthesis, which equals 10. Then you add the 5, which equals 15.

A store sells shirts at a price of 2 for $5.00. At this price, how much do 7 shirts cost?

Answers

Answer:

$17.50

Step-by-step explanation:

2 goes into 7 3 times, and 5 times 3 is $15.00, so theres one shirt left. If 2 shirts cost $5, one will cost $2.50. So, 15+2.50= $17.50

5/2 equals 2.50 so 2.50x7 equals 17.50

Step-by-step explanation:

[tex] {x}^{2} - 11x + 18 = 0[/tex]

[tex] = > {x}^{2} - 9x - 2x + 18 = 0[/tex]

[tex] = > x(x - 9) - 2(x - 9) = 0[/tex]

[tex] = > (x - 9)(x - 2) = 0[/tex]

Here x will have 2 solutions.

Connor is correct because the water is flowing in at a rate which is about 2 gallons per minute.

Connor is not correct because the water is flowing in at a rate which is faster than 2 gallons per minute.

Connor is not correct because the water is flowing in at a rate which is slower than 2 gallons per minute.

Connor is correct because the rate of water flowing is less than the slope.

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 Resort has 68 inches of snow. Currently it is snowing there at a rate of 2 inches per hour.

a) Make a table or a graph showing the amount of snow from 0 to 10 hours at each resort if the snow continues falling at this rate.

b) Indicate on your table or graph where the amount of snow will be the same at both resorts.

Answers

Answer:

a. See explanation for table

b. The 7th hour

Step-by-step explanation:

Given

Ski Resort

[tex]Base\ Snow = 75in[/tex]

[tex]Rate = 1in[/tex] hourly

Mt. Winterpark

[tex]Base\ Snow = 68in[/tex]

[tex]Rate = 2in[/tex] hourly

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

[tex]Amount = Base\ Snow + Rate * Time[/tex]

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

So:

Ski Resort

[tex]y= 75 + 1* x[/tex]

[tex]y= 75 + x[/tex]

Mt. Winterpark

[tex]y= 68 + 2 * x[/tex]

[tex]y= 68 + 2x[/tex]

Next, we make a table to show the data.

When [tex]x = 0[/tex]

Ski Resort: [tex]y = 75 + 0 = 75[/tex]

Mt. Winterpark: [tex]y = 68 + 2(0) = 68[/tex]

When [tex]x = 1[/tex]

Ski Resort: [tex]y = 75 + 1 = 76[/tex]

Mt. Winterpark: [tex]y = 68 + 2(1) = 70[/tex]

When [tex]x = 2[/tex]

Ski Resort: [tex]y = 75 + 2 = 77[/tex]

Mt. Winterpark: [tex]y = 68 + 2(2) = 72[/tex]

When [tex]x = 3[/tex]

Ski Resort: [tex]y = 75 + 3 = 78[/tex]

Mt. Winterpark: [tex]y = 68 + 2(3) = 74[/tex]

When [tex]x = 4[/tex]

Ski Resort: [tex]y = 75 + 4 = 79[/tex]

Mt. Winterpark: [tex]y = 68 + 2(4) = 76[/tex]

When [tex]x = 5[/tex]

Ski Resort: [tex]y = 75 + 5 = 80[/tex]

Mt. Winterpark: [tex]y = 68 + 2(5) = 78[/tex]

When [tex]x = 6[/tex]

Ski Resort: [tex]y = 75 + 6 = 81[/tex]

Mt. Winterpark: [tex]y = 68 + 2(6) = 80[/tex]

When [tex]x = 7[/tex]

Ski Resort: [tex]y = 75 + 7 = 82[/tex]

Mt. Winterpark: [tex]y = 68 + 2(7) = 82[/tex]

When [tex]x = 8[/tex]

Ski Resort: [tex]y = 75 + 8 = 83[/tex]

Mt. Winterpark: [tex]y = 68 + 2(8) = 84[/tex]

When [tex]x = 9[/tex]

Ski Resort: [tex]y = 75 + 9 = 84[/tex]

Mt. Winterpark: [tex]y = 68 + 2(9) = 86[/tex]

When [tex]x = 10[/tex]

Ski Resort: [tex]y = 75 + 10 = 85[/tex]

Mt. Winterpark: [tex]y = 68 + 2(10) = 88[/tex]

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

A line has a slope of 9 and passes through the point (4, 5). What is its equation in point-slope form?​

Answers

Answer:

y - 5 = 9 (x-4)

Step-by-step explanation:

Point-slope form of the line that passes through (-8,2) and is perpendicular to a line with a slope of -8

Answers

Answer:

y-2=1/8(x+5)

Step-by-step explanation:

1. Perpendicular lines have opposite slopes. To get the new slope, take the slope of the first line and turn it to make it the opposite reciprocal.

Since it's -8, the opposite of it is 1/8.

2. Now, use point slope: y-y1=m(x-x1). Plug in the values of the ordered pair and the slope into the equation.

y-2=1/8(x+8)

And that's your answer
