Answer:

D. x2 = 52 + 32 – 2(5)(3)cos(140°)

Step-by-step explanation:

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.

Distance is a numerical representation of the distance between two objects or locations.

The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.

The distance, x, from the starting point is;

From the cos law ;

x² = a² +b²-2ab cosΘ

From the digrame it is obtained that;

a =5

b =3

Θ = 180 ° +70° -30°

Θ = 180°- 40°

Θ = 140°

Substitute the values;

x² = a² +b²-2ab cosΘ

x²=5²+3²-2(5)(3)cos(140°)

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°).

Hence option B is corect.

Step-by-step explanation:

Answer:

The percentage of people who are satisfied with this car model is 30%.

Step-by-step explanation:

Given that the survey interviewed 1,900 people who own a certain type of car, and of them 570 said that they would buy the same car model again, to determine the percentage of people who are satisfied with that model it is necessary to perform the following calculation :

1,900 = 100

570 = X

((570 x 100) / 1,900) = X

57,000 / 1,900 = X

30 = X

Therefore, the percentage of people who are satisfied with this car model is 30%.

Answer:

Fourth choice, 1/6

Step-by-step explanation:

15 + 8 + 10 + 12 + 15 = 60

Out of 60 cards, 10 of them is the go again card, so it's 10/60 which simplified is 1/6

Answer:

8.33%

Step-by-step explanation:

We are told to:

Express the first quantity as a percentage of the second

a. 80cents of $9.60

The first quantity is 80 cents, the second quantity is $9.60

Step 1

We convert 80 cents to a dollar

100 cents = $1

80 cents = $x

$x = 80/100 = $0.8

Step 2

We express $0.8 as a percentage of $9.60

Hence, we have:

$0.8/$9.60 × 100

= 8.33%

Answer:

c

Step-by-step explanation:

Given the2 equations

y = x + 4 → (1)

x + y = 2 → (2)

Substitute y = x + 4 into (2)

x+ x + 4 = 2

2x + 4 = 2 ( subtract 4 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = - 1 + 4 = 3

solution is (- 1, 3 ) → c

Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)

Substitute the given vector into the expression for vec t.

Recall that: vec t = 4 vec u +6 vec v

vec t = 4(-1,4)+6(3,-2)

vec t = (4(-1), 4(4)) + (6(3), 6(-2))

vec t = (-4, 16) + (18, -12)

vec t = (-4+18, 16+(-12))

vec t = (14, 16-12)

vec t = (14, 4)

Hence an ordered pair to represent vec t in the equation is (14, 4)

Note that the vec v was assumed. Any other vector coordinate can also be used

Answer:

45

Step-by-step explanation:

∡L ≅ ∡M, given  

ΔKLM is isosceles because base angles are congruent

KM ≅ KL and KM = KL

KL = 12

∡K =∡J = 60°, given

∡M = 180 -60 -60 , because sum of angles in a Δ is equal to 180°

∡M = 60

∡K =∡J =∡M =  60°

ΔKJM is is equilateral because all angles have the same measure.

KM = 12

KM = KJ = JM = 12 because the triangle is equilateral so all sides are equal

ML = 9, given

The perimeter of JKLM is the sum of the sides

P = ML +KL +KJ +MJ

P = 9 + 12 + 12 +12 = 9 +36 = 45

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

To find the slope of a line, we would need to use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]. These points can be any two points that fall on the line.

In the graph, two points we can use to find the slope is (1, 2) and (-2, 0).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\\\frac{0-2}{-2-1} \\= \frac{-2}{-3} \\= \frac{2}{3}[/tex]

Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:

24

Step-by-step explanation:

Corey has saved an amount of 24 dollars, if they have saved up a total of $78.00.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume that Corey has saved an amount of x dollars.

Given that Jasper and Corey have saved up a total of $78.00.

Jasper has saved 6 dollars more than twice as much as

Corey.

As per the given condition, the algebraic form is:

(6 + 2x) + x = 78.  

Rearrange the terms of variables of x in the above equation,

6 + 2x + x = 78

Apply the addition operation,

6 + 3x = 78

Subtract 6 from both sides in the equation,

3x = 72

Now divide both sides by 3 in the equation,

x = 24

Therefore, Corey has saved an amount of 24 dollars.

Answer:

Annual deposit= $4,699.46

Step-by-step explanation:

Giving the following information:

Future value (FV)= $25,000

Number of periods (n)= 5 years

Interest rate (i)= 3.1% = 0.031

To calculate the annual deposit, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (25,000*0.031) / [(1.031^5) - 1]

A= $4,699.46

Answer:

Jazmine will pay only $40 for both discounts.

Step-by-step explanation:

First we need to add the two discounts, 35% + 25% = 60%.

Now we need to convert 60% into a decimal, which is 0.60.

Now we need to multiply the regular price, $100, by 0.60.

$0.60 × $100 = $60.

Now we subtract the discount by the amount, $100 - $60 = $40.
