The sum of two or more vectors is called the Resultant.

The Resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.

[tex]$$\mathrm{A}_{\mathrm{x}}=-3.00, \mathrm{~A}_{\mathrm{y}}=2.00$$(a) $\overrightarrow{\mathrm{A}}=\mathrm{A}_{\mathrm{x}} \hat{\mathrm{i}}+\mathrm{A}_{\mathrm{y}} \hat{\mathrm{j}}=-3.00 \hat{\mathrm{i}}+2.00 \hat{\mathrm{j}}$(b) $|\overrightarrow{\mathrm{A}}|=\sqrt{\mathrm{A}_{\mathrm{z}}^2+\mathrm{A}_{\mathrm{y}}^2}=\sqrt{(-3.00)^2+(2.00)^2}=3.61$$$\theta=\tan ^{-1}\left(\frac{\mathrm{A}_{\mathrm{Y}}}{\mathrm{A}_{\mathrm{K}}}\right)=\tan ^{-1}\left(\frac{2.00}{-3.00}\right)=-33.7^0$$[/tex]

[tex]$\theta=180^{\circ}+\left(-33.7^{\circ}\right)=146^{\circ}$[/tex]

[tex]$\mathrm{R}_{\mathrm{x}}=0, \mathrm{R}_{\mathrm{y}}=-4.00$ and $\overrightarrow{\mathrm{R}}=\overrightarrow{\mathrm{A}}+\overrightarrow{\mathrm{B}}$, thus $\overrightarrow{\mathrm{B}}=\overrightarrow{\mathrm{R}}-\overrightarrow{\mathrm{A}}$ and$$\mathrm{B}_{\mathrm{x}}=\mathrm{R}_{\mathrm{x}}-\mathrm{A}_{\mathrm{x}}=0-(-3.00)=3.00, \mathrm{~B}_{\mathrm{y}}=\mathrm{R}_{\mathrm{y}}-\mathrm{A}_{\mathrm{y}}=-4.00-2.00=-6.00$$[/tex]

[tex]\text { Therefore, } \overrightarrow{\mathrm{a,b}}=3.00 \hat{i}+6.00 \hat{j}[/tex]

Step-by-step explanation:

90× 60% = 54

Answer:

Please check the explanation.

Step-by-step explanation:

We know that if we multiply 3 and 4, we get 12.

In other words, 3 × 4 = 12

Thus, 3 and 4 are factors of 12.

now

Given the expression

[tex](a+b+c)(d+e+f)[/tex]

The given expression consists of two factors which are:

We also know that an expression can consist of terms, a term may be a constant or a variable. It can be both as well.

For example, in the expression, 4b + 2, 4b and 2 are terms.

so,

The property of equality that justifies the statement where the statement is given as "If VR + TY = EN + TY, then VR = EN" is the subtraction property of equality

The statement is given as

If VR + TY = EN + TY, then VR=EN

In the above statement, we have the following equation

VR + TY = EN + TY

By applying the subtraction property of equality, we have the following equation

So, we have

VR + TY - TY = EN + TY - TY

Evaluate the  difference in the above equation

So, we have

VR = EN

Hence, the property of equality that justifies the statement where the statement is given as "If VR + TY = EN + TY, then VR = EN" is the subtraction property of equality

The 10 comes from how many time 6 minutes can go into 60 = 1hr

Answer:

No. Jami can mow more than her advertisement states

Step-by-step explanation:

Because she can mow 1/6 of an acre in 6 minutes, and an hour is 60 minutes long, we know that she can mow up to ten times that in one hour. Think about it this way. How many times does six minutes go into 60? 10. So Jami can mow 1/6 of an acre up to 10 times in one hour. This means that in an hour Jami can mow 10/6, or 1 and 2/3 of an acre in an hour. Thus, her advertisement is understating how quickly she can mow.

Answer:You have 2 cards upfront, so the constant term in this linear equation is 2.  The slope represents how many more cards you buy or acquire per day, week or month (depending upon how eager you are to fatten your collection).  ;)

y = 2 + (rate of acquisition of cards)(time)

y = 2 + rt

Answer:

120

Step-by-step explanation:

Exterior angle theorem

50 + 70 = 120

Answer:

120

Step-by-step explanation:

the insides of a triangle add up to 180 degrees. You're given 70 and 50 degrees which add to 120 and that means the other angle is 60 degrees. Since you're trying to find an outside angle, you need to do subtract the 60 degrees we just found from 180 (because its a supplementary angle). 180-60 is 120 and thats the answer

The Inequality Equation =

The number of T -shirts Debbie can buy is at most 4 T-shirts

Step-by-step explanation:

Let the number of T shirts Debbie can buy be represented as x

We are told in the question: Debbie has at most $58 to spend on clothes.

This means she would not exceed $58. She would be spending less than or equal to $58

The Inequality Equation =

$22 + $9 × x ≤ $58

22 + 9x ≤ 58

Solving the Inequality Equation above:

22 + 9x ≤ 58

9x ≤ 58 - 22

9x ≤ 36

x ≤ 36/9

x ≤ 4 shirts

The number of T -shirts Debbie can buy is at most 4 T-shirts

Answer:

6,053.29

Step-by-step explanation:

Use this formula:

A= p(1+r/n)^nt

A= Amount (?)

P= Principal (4600)

r - interest rate (4%)

n= number of times the interest is compounded per year (1)

t= time (7 years)

Answer:

£6053.29 to the nearest penny.

Step-by-step explanation:

Amount after 7 years = 4600(1 + 0.04)^7

= 4600 * 1.04^7

= £6053.286.

0.25x+1y=12 is the answer, because you are multiplying 0.25 and 1 to see how many games/rides there were.

Answer:

The first one

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The weight of the weight lighting bar = the initial value/y-intercept (b) = 45

Amount of weight = x

Total amount of weight = y

The rate of change (m) = 1

Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b

Thus:

y = (1)x + 45

y = x + 45

The correct option is c

Answer:

$99.91

Step-by-step explanation:

If the markup is 60.5%, then the selling price would be 160.5% of the original price.

160.5%=1.605

Answer:

K is -12/5

k is also 28/5

Step-by-step explanation:

Here, we want to solve the equation

|5k-8| = 10(2)

5k-8 = 20

5k = 20 + 8

5k = 28

k = 28/5

or

5k-8 = -20

5k = -20 + 8

5k = -12

k = -12/5
