Hello! if anyone could help me I'd really appreciate it!. Thanks !​

Answer:

A

Step-by-step explanation:

The magnitude and direction angle of c is 12.8 and 128.7° respectively.

"A vector contains two types of information: a magnitude and a direction. The magnitude is the length of the vector while the direction tells us which way the vector points.

Vector direction can be given in various forms, but is most commonly denoted in degrees. Acceleration and velocity are examples of vectors."

Given: a = (5, –9) and b = (–3, 1) and c = b – a.

Therefore, c = (5+3, -9-1) = (8, -10)

Now, magnitude of c is [tex]\sqrt{8^{2}+(-10)^{2}}[/tex] = 12.8

The direction of c is Ф = tan⁻¹(-10/8) = -51.3°

Therefore, the direction of c is 180° - 51.3° = 128.7°  (tanФ = tan(π+Ф))

Answer:

from least to greatest or what? ill do lest to greatest tho

-7/8, -13/16, -1 4/5, 7/4

Step-by-step explanation:

all of these can be converted into a fraction with a denominator of 16 so you can compare easier except for -1 4/5 but that is the highest negative number so that would be the last one you put down because it has a whole number so it is greater than one therefor being greater than the rest of the negative fractions that are less than one, but for the rest, it is just simple least to greatest *(if it is greatest to least just reverse it)*

Answer:

From least to greatest: -1 4/5, -7/8, -13/16, 7/4

Greatest to least: 7/4, -13/16, -7/8, -1 4/5

Step-by-step explanation: Start with the greatest number. This would be 7/4 since it is the only positive number in the set of numbers. Then, find a common denominator for the rest of the numbers/fractions. To save time, a common denominator of -7/8, -1 4/5 and -13/16 is 80. Then, make all the equations equivalent. To do this, I’ll just use -13/16. So, just multiply 5 by 16 and -13 by 5 to get the right fraction. The answer would be -65/80 and you would do this process for the rest of the numbers. Once your done with this explanation, just remember that a lower negative number has a higher value on the number line making it greater in a set of numbers.

Step-by-step explanation:

Interval Notation:

(-11,\infty )

Answer:

Step-by-step explanation:

4x + 23 > -21

4x > -21 -23  (moving 23 to the right side of equation changes the +23 to  -23

4x > -44  (adding -21 to -23)

x > -11  (dividing both sides of equation by 4, this keeps the equation the same

Solution:  x > -11  (x is greater than negative 11)

Answer:

(-2.-8) is the answer to the question

The solution of the inequality equation 7x - 4y < 18 will be (-2, -8) and yes, it has a solution.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

For each ordered pair (x, y), determine whether it is a solution to the inequality 7x - 4y < 18.

The equation is satisfied by the point (-2,– 8). Then we have

     7x - 4y = 18

7(-2) - 4(-8) = 18

    -14 + 32 = 18

              18 = 18

Answer: linear function is 25x + 20

After 8 weeks he has saved 25(8)+20 which is 200, so he saved $200 after 8 weeks.

Step-by-step explanation:

Ok so we say 25x because x is any amount of weeks he has saved for and because he had a head start of $20, we add 20 when calculating after any amount of weeks( because even if we know he saved 25x after x weeks we have to add the 20 dollars he also started with)

I hope this helps:)

Answer:

a. 20 + 25x

where x is the no. of weeks

b. The amount saved after 8 weeks = 20 + 25 (8)

= 20 + 200

= 220

Therefore, $220 will be saved after 8 weeks.

The recursive rule for the sequence is a[tex]_{1}[/tex] = 75; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + 25

Step-by-step explanation:

the recursive rule of an arithmetic function is a[tex]_{1}[/tex] = first term; a[tex]_{n}[/tex]= a[tex]_{n-1}[/tex] + d, where

∵ The given is 75, 100, 125, 150, .......

∵ 100 - 75 = 25

∵ 125 - 100 = 25

∵ 150 - 125 = 25

∴ The common difference is 25

∴ d = 25

∵ The first term is 75

∴ a[tex]_{1}[/tex] = 75

→ Substutute the values of a1 and d in the formula above

∴ The recursive rule for the sequence is a[tex]_{1}[/tex] = 75; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + 25

HOPE THIS HELPED

Step-by-step explanation:

For them to owe you a total of$2000 then an interest of $2000-320=$1680 must have accrued over the time T

T=$1680×100/320×11

T=47.7272...≈47.73 to the nearest hundredth

Proof,

Interest after 47.7262...years which is converted to 525/11 years

=($320×11×525/11)/100

=$1680

therefore total amount which will be owed at that time =principal+interest accrued

=$320+1680=$2000

Answer:

[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]

Step-by-step explanation:

Given the expression

[tex]-\left(5.3x-7y\right)\times \left(-9.6\right)[/tex]

[tex]=-\left(-9.6\right)\left(5.3x-7y\right)[/tex]

Apply distributive law

[tex]a\left(b-c\right)=ab-ac[/tex]

[tex]a=-\left(-9.6\right),\:b=5.3x,\:c=7y[/tex]

so the expression becomes

[tex]=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y[/tex]

[tex]=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y[/tex]    ∵ [tex]-\left(-a\right)=a[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a[/tex]

[tex]=9.6\times \:5.3x-7\times \:9.6y[/tex]

[tex]=50.88x-7\times \:9.6y[/tex]

[tex]=50.88x-67.2y[/tex]

Therefore,

[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]

Answer:

S = 32.1 m/s

Step-by-step explanation:

P = 1,500

S = 30

since P is proportional to S², then we must first determine S² = 900

900 / 1,500 = S² / 1,715

(900 x 1,715) / 1,500 = S²

1,543,500 / 1,500 = S²

S² = 1,029

S = √1,029 = 32.08 m/s ≈ 32.1 m/s
