Find the component form and the magnitude of the vector v. Exact number, no deciment
Please help I try 7 times but it still wrong
Answers
Answer:
[tex]\sqrt{13}[/tex] = 3.6
Step-by-step explanation:
to find the magnitude of a vector the equation is
|v| = [tex]\sqrt{x component ^{2} + y component^{2} }[/tex]
v = [tex]\sqrt{9+4}[/tex] = [tex]\sqrt{13}[/tex]
Answer:
Step-by-step explanation:
Component form : (3 , -2)
Magnitude = [tex]\sqrt{3^{2}+ (-2)^{2}} \\[/tex]
[tex]= \sqrt{9+4}\\\\= \sqrt{13}[/tex]

Write and solve an inequality that represents the values of x for which the area of the rectangle will be at least 35 square feet.

Explanation:
There really is not enough information here. You have not indicated how x is related to the rectangle.Perhaps (as an alternative to the assumption I made [above]), you meant for x > 0 to be the length of one side of a square.

Answers
Answer:
Area: 378.5
Perimeter: 71.4
Step-by-step explanation:
Area = 3 square + 2 semicircle
A = 3 x 10² + 2 x (3.14 x 5²)/2 = 300 + 78.5 = 378.5
perimeter = 2 square/2 + 2circle/2
P = 2 x(10 + 10) + 2 x (2 x 3.14 x 5) / 2 = 40 + 31.4 = 71.4

Step-by-step explanation:
(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)
Apply the distributive property to remove the parentheses
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
Combine like terms together and arrange in standard form
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn

What is the perimeter of ABC with vertices A (-2,9) , B (7,-3) , C (-2,-3) in the coordinate plane?
A. 21 units
B. 15 units
C. 34 units
D. 36 units
Answers
9514 1404 393
Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.

A TV has an original price of $599. Enter the new price after the given percent of change.
20% increase
The percent decrease is ? %
Answers
Answer:
The new price = $718. 8
Step-by-step explanation:
Original Price = $599
Given that the increase is 20%.
i.e.
Thus,
The amount of 20% Percentage increase = 20/100 × 599
= 0.2 × 599
= $119.8
Therefore,
New price = Original price + 20% increase amount
= 599 + 119.8
= $718. 8
Therefore, the new price = $718. 8

To find the next number in the sequence, you have to subtract 2 from the last number.Because it started on 27 (which is an odd number) and we're subtracting 2 each time, every number in the sequence will be odd. And because -351 is an odd number, it will be in the sequence.I hope this helps!

The ratio of boys to girls at a movie is 4:5. If there are 15 girls, how many boys are at the movie?
Answers
Answer:
There are 12 boys at the movie.
Step-by-step explanation:
Key skills needed in order to solve: Proportions, Ratios, and Multiplication
1) The ratio is 4 boys : 5 girls --> It can be written as a fraction --> 4/5
2) If there are 15 girls, we need to find the number of boys. let's say x is the number of boys when there are 15 girls. The ratio would then be x/15
3) Make a proportion --> [tex]\frac{4}{5}[/tex] = [tex]\frac{x}{15}[/tex]
You have to cross multiply here. You do the first fraction's numerator times the second fraction's denominator, and the first fraction's denominator times the second fraction's numerator.
4) This means you have to do: 4(15) = 5(x)
5) Multiply it out --> 60=5x
6) Divide by 5 and you will get x=12
Therefore there are 12 boys at the movie.

p=7q-3 make q the subject
Answers
Answer:
q = (P + 3) / 7
Step-by-step explanation:
Give the expression :
P=7q-3
To make q the subject
Isolate 7q by adding 3 to both sides
P + 3 = 7q + 3
P + 3 = 7q
To. Isolate q alone, multiply both sides by 1/7
(P + 3) * 1/7 = 7q * 1/7
(P + 3) / 7 = q
q = (P + 3) / 7
