Answer:
First year would be 9180 and the second year would be 9363.6
Step-by-step explanation:
I just take the interest 2% make it a decimal .02 and times that by 9000 which gives you 180 then just add that to the 9000 for the first year and then for the second take 9180 times .02 which gives you 183.6 and just add that too 9180 to get 9363.6
If your expression contains square roots, during which step of PEMDAS do you solve them? A parentheses B exponents C multiplication D division
Answer:
B
Step-by-step explanation:
Roots can also be represented as indicies (exponents) and thus should be treated like them. For example, square root could also be written as exponent 1/2.
When dealing with square roots in a equation, PEMDAS calls for this to be solved when you do B. Exponents
The root of a number is that number expressed exponentially by the root in inverted form. In other words, when you take something to its square root, you would be taking it to the inverse of 2 which is 1/2.
For instance:
√4 = 2 = 4¹/²
This means that you can then solve the square root when you deal with exponents which is the second step.
In conclusion, if you see an expression with square roots, PEMDAS allows you to solve it as an exponent.

As of July 2012, the world record for the 100 meter dash is held by Usain Bolt of Jamaica, who finished such a race in 9.572 seconds in Berlin, Germany, on August 16, 2009. Calculate Bolt’s average race speed in miles per hour. Show all work. Use a conversion rate of 1 mi ~ 1.609 km. Round to three decimal places.
Answer:
v = 23.370 mph
Step-by-step explanation:
It is given that,
The world record for the 100 meter dash is finished in 9.572 seconds in Berlin. We need to find the Bolt’s average race speed in miles per hour.
We know that,
1 mile = 1.609 km
or
1 mile = 1609.34 m
⇒ 100 m = 0.0621 miles
1 hour = 3600 seconds
⇒ 1 second = (1/3600) hour
Average speed = distance/time
So,
[tex]v=\dfrac{\dfrac{100}{1609.34 }\text{miles}}{\dfrac{9.572}{3600}\ \text{hour}}\\\\v=23.36963\ \text{mph}[/tex]
or
v = 23.370 mph
Hence, Bolt’s average race speed is 23.370 mph.

Find projvu and projuv. Use the Euclidean inner product. u = (1, −1, −2), v = (1, 1, 2)(a) projvu(b) projuv
Answer:
Step-by-step explanation:
Given the vectors u = (1, −1, −2) and v = (1, 1, 2),
projection of u on v is expressed as [tex]proj_v u = \dfrac{u*v}{|v|^2}*v[/tex]
u.v = (1, −1, −2).(1, 1, 2)
u.v = 1(1)+(-1)(1)+(-2)(2)
u.v = 1-1-4
u.v = -4
|v| = √1²+1²+ 2²
|v| = √1+1+4
|v| = √6
|v|² = (√6)²
|v|² = 6
[tex]proj_v u = \dfrac{-4}{6}*(1,1,2)\\proj_v u = (\dfrac{-4}{6}, \dfrac{-4}{6}, \dfrac{-4}{3} )[/tex]
Similarly for projection of v on u;
[tex]proj_u v = \dfrac{u*v}{|u|^2}*u[/tex]
|u| = √1²+(-1)²+ (-2)²
|u| = √1+1+4
|u| = √6
|u|² = (√6)²
|u|² = 6
[tex]proj_u v = \dfrac{-4}{6}*(1,-1,-2)\\proj_u v = (\dfrac{-4}{6}, \dfrac{4}{6}, \dfrac{4}{3} )[/tex]

Consider the function f(x) = round(x), which rounds the input, x, to the nearest integer. Is this function one-to-one? Explain or justify your answer.
Answer:
No, it's not a one-to-one function
Step-by-step explanation:
Given
[tex]f(x) = round(x)[/tex]
Required
Determine if this function is one-to-one
I'll answer this question using the following illustrations;
Assume x = 4.6
[tex]f(x) = round(x)[/tex] would be
[tex]f(4.6) = round(4.6)[/tex]
[tex]f(4.6) = 5[/tex]
Also assume x = 4.8
[tex]f(x) = round(x)[/tex] would be
[tex]f(4.8) = round(4.8)[/tex]
[tex]f(4.8) = 5[/tex]
More generally;
[tex]4.5 \leq\ x\leq\5.4[/tex]
Would result in:
[tex]f(x) = 5[/tex]
Since, there's a always a possibility of f(x) having one value for various values of input x, then we can conclude that the function is not a one-to-one function
The function f(x) = round(x) is not one - to - one since different input values of X could yield the same output.
One - to - one functions refers to functions which yield a different output for every input value given. Since, the function rounds input values of x to the nearest integer ;This means that ; some input values of x would produce similar output.For instance :
Given that x = 1.4
f(x) = round(x)
f(1.4) = round(1.4)
Output = 1 ( nearest integer)
Thus output will be the same for all values of x greater than equal to 1 and less than 1.5 (1 ≤ x < 1.5)Since, different input values of X could yield the same the output, then the function is not one - to - one.

1. A student in an algebra course has test scores of 75, 82, 71, and 84. What score on the next test will raise the student’s average to 80?
Hey there! I'm happy to help!
We have 5 numbers that will give us an average score of 80.
75,82,71,84,x
What we do is add these all up and divide by 5 to get 80. Let's go backwards to find x.
We multiply by 5.
80(5)=400
We subtract all of the numbers except for x.
400-75-82-71-84=88
Therefore, the score on the next test has to be 88 to have the student's average be 80.

The figures are similar. Find x
Answer: x=6.67
Step-by-step explanation:
Since these parallelograms are similar, we can use proportions to solve for x.
[tex]\frac{15}{9} =\frac{x}{4}[/tex] [cross multiply]
[tex]60=9x[/tex] [divide both sides by 9]
[tex]x=6.67[/tex]
Now, we know that x=6.67.
Answer:
20/3
Step-by-step explanation:
9/4=15/x
cross multiply and get:
9x=15x4
9x=60
divide both sides by 9 so
x=60/9 which when simplified is equal to 20/3
ABC is an isosceles triangle. Solve for x. In your final answer, include all of the necessary calculations. You may include a sketch as part of your calculations.
Answer:
x= 105
Step-by-step explanation:
Let the unknown angle at the base be y. We know the base angles of an isosceles triangle are the same
The sum of the angles of the triangles are
30 + y +y = 180
30 + 2y = 180
2y = 180-30
2y = 150
y = 75
We know that x+y = 180 since it forms a straight line
x+75 =180
x = 180-75
x = 105
Answer:The abc conjecture It is stated in terms of three positive integers, a, b and c (hence the name) that are relatively prime and satisfy a + b = c. So a conjecture is like an educated guess.

O
B. 18 m2
O
C. 21 m2
O
D. 35 m2
Answer:
Area of the trapezoid = 18 m²
Step-by-step explanation:
Formula to calculate the area of a trapezoid is,
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Where [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid
And h = distance between the parallel sides
From the figure attached,
[tex]b_1[/tex] = 5 m
[tex]b_2[/tex] = (6 + 1) = 7 m
h = 3 m
By substituting these values in the formula,
Area of a trapezoid = [tex]\frac{1}{2}(5+7)3[/tex]
= 6 × 3
= 18 m²
Therefore, area of the given trapezoid is 18 m².
a machinist can produce 114 parts in 6 minutes. at this rate, how many parts can the machinist produce in 15 minutes
Answer:
285!
Step-by-step explanation:
First you have to find out how may parts are produced in a single minute.
We know that 114 parts are produced in 6 minutes so to find how may parts are made in one minute divide 114 by 6 and get an answer of 19
114÷6=19
Now to find how may parts are produced in 15 minutes multiply 19 (number of parts produdced in one minute) by 15 and get an answer of 285!
19×15=285
