Answer: v = u= [tex]2 \sqrt{2}[/tex]
Step-by-step explanation:
v= cos45 * 4= [tex]2 \sqrt{2}[/tex]
- Apply Pythagorean theorem
[tex]4^{2}[/tex]= [tex](2\sqrt{2}) ^{2} + u^{2}[/tex]
We have u = [tex]2 \sqrt{2}[/tex]

For each question order the cards from least to greatest. If the feature is equal to two or more functions, place them next to each other. y-coordinate of the y-intercept
(the letters/cards need to be put in order form least to greatest based on y-coordinate of the y-intercept)
Answer:
C, D (-4) ⇒ E, G (0) ⇒ H (1) ⇒ A, F (3) ⇒ B(8)Step-by-step explanation:
The y-intercept is the coordinate of y at x = 0.
Let's find them all and then order.
A)
a(0) = -2*0 + 3 = 3B)
b(0) = 8 as per graphC)
c(0) = - 4 as per graphD)
d(0) = 0² - 4 = - 4E)
The point to be found after the equation of the function e(x)
We can see it is a linear function as the rate of change is constant
Use two points from the table (-1, 2) and (1, -2), find the slope:
m = (-2 - 2)/(1 - (-1)) = -4/2 = -2Use one point to find the y-intercept:
y - 2 = -2(x - (-1))y - 2 = -2x - 2y = -2x e(x) = -2xe(0) = 0F)
f(0) = 3 as per graphG)
g(0) = 2(3⁰) - 2 = 2 - 2 = 0H)
h(0) = 1 as per tableclassifying triangles

If the principal is $4,500 and the rate of interest is 8%, what is the amount of interest after one year? Formula is I =PRT
Step-by-step explanation:
I=?
P= $4500
R=8%=0.08
T=1 year
8%*0.01= 0.08
I=(4500)(0.08)(1)
(4500)(0.08)=360
360*1=360
The interest after one year is $360

I MARK THE BRAINLIST
Answer:
1.6
Step-by-step explanation:
Hi there!
[tex]\large\boxed{D = 1.6}[/tex]
To find the decimal, we must look at the amount of subdivisions between 1 and 2.
Counting, we get 10 divisions, so each increment is by 0.1.
D is located at the sixth line from 1, so:
1 + 6(0.1) = 1 + 0.6 = 1.6

Sam is using the expression m/8n in class. what is the value of the expression when m = 4 and n = 1/2?
Answer:
1
Step-by-step explanation:
m/8n > 4/8(1/2) ( since its 1/2 all u need to do is change the fraction to whole number which is 1/2 = 0.5)
The given will become 4/4 then simplest form is 1
A chipmunk population is experiencing exponential growth with a population growth rate of 265 individuals/year, and a per capita rate of increase of 0.15. How many chipmunks are currently in this population
Answer:
There are 1766 chipmunks in the population
Step-by-step explanation:
Number of individuals increasing per year = 265
Rate of increase = 0.15
Rate of increase = increase in number of individuals in a given population /total population
Substituting the given values, we get -
0.15 = (265/total population)
Total population = 265/0.15 = 1766

Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a certificate. Write a letter to Marcus explaining whether or not he will be receiving a certificate. Include a brief summary of your statistical analysis in your letter.
Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

5/8+3/4 over this problem(/) -2/3-5/6.
Answer:
5/8 + 3/4= 11/8
-2/3-5/6 =-3/2
Since the second is dividing the first
11/8 ÷ -3/2
Flipping; Then change the bottom to the top(Do this to the second fraction)
11/8 x -2/3
=-11/12.

Answer:
169.646003294, hope this helps
Step-by-step explanation:
To solve this equation,
A= [tex]2\pi rh+2\pi r^{2}[/tex]
Since the radius is 3 meters. We know what r is. A radius of a circle or sphere is any of the line segments from its center to the perimeter. The height is 6 meters.
[tex]A=2\pi (3)*6+2\pi (3^2)\\ A=2\pi (18)+2\pi 9\\ A=113.097...+2\pi 9\\ A=113.097+56.548...\\ A=169.64600...[/tex]

Applying the 45-45-90 Theorem, Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 4√2 inches and one of the angles is 45°.
Rule: If x is the leg of a 45-45-90 triangle, then x*sqrt(2) is the hypotenuse.
We can prove this by showing that x^2+x^2 = (x*sqrt(2))^2 is an identity. It's from the pythagorean theorem a^2+b^2 = c^2.
Put another way, if we know that a = x and b = x are the two congruent legs, then x^2+x^2 = c^2 leads to c = x*sqrt(2). This triangle is known as an isosceles right triangle.
So if 4*sqrt(2) is the hypotenuse, we match that up with the template x*sqrt(2) and see that x = 4 must be the case.

Solve the expression below: 3(x-3) + 2x(4x+6)=
The length of 12cm and 5 cm missing one
Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm

____________________Solution :-Given Information :-Fraction 1 ➢ [tex] \sf12 \frac{1}{2} [/tex]Fraction 2 ➢ [tex] \sf -4 \frac{1}{2} [/tex]Operation ➢ Subtraction To Find :-The difference between two fractionsCalculation :-[tex] \sf: \implies \sf12 \frac{1}{2} - ( - 4 \frac{1}{2} ) = \boxed{ ? }[/tex]
Firstly, converting mixed fractions to improper fractions, We get,
[tex] \sf: \implies \frac{25}{2} - ( - \frac{9}{2} ) = \boxed?[/tex]
Now, solving the parentheses, We get,
[tex] \sf: \implies \frac{25}{2} + \frac{9}{2} = \boxed ?[/tex]
Since, We have like terms, We will directly add up the two fractions, We get,
[tex] \sf: \implies \frac{25 + 9}{2} = \boxed?[/tex]
Calculating further, We get,
[tex] \sf: \implies \frac{34}{2} = \boxed?[/tex]
Bringing the fraction to it's lowest terms, We get,
