A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.8%. How much interest will the customer earn in 10 years? b. What will the account balance be after 10 years?
Answer: See explanation
Step-by-step explanation:
The Simple Interest will be calculated as:
= P × R × T
= $3000 × 1.8% × 10.
= $3000 × 0.018 × 10
= $540
The interest that the customer earn in 10 years is $540.
Then, the account balance after 10 years will be:
= Principal + Interest
= $3000 + $540
= $3540
Therefore, the account balance will be $3540

We can plot these two points and draw a line through them to get the border of the inequality:
graph{(x^2+(y-2)^2-0.075)((x-4)^2+y^2-0.075)(x+2y-4)=0}
The line will be solid because the inequality operator has a "or equal to" clause in it. We can now shade the area to the right of the line because the inequality has a "great than" clause in it.
graph{(x+2y-4)>=0}
Question 4 of 10 Based only on the information given in the diagram, it is guaranteed that A ABC - AXYZ. 3 Y Z O A. True B. False
Answer: True
Step-by-step explanation:
We know in every triangle all the angles add up to 180 so for triangle ABC if you add the 52 to the 90 you’ll find the answer to be 142 if you subtract this then from 180 you’ll find 38 to be your answer
Therefore if you add the 38 the 52 and the 90 you’ll get 180
Based only on the information given in the diagram, it is guaranteed that Δ ABC ≅ Δ XYZ. It is true that Δ ABC ≅ Δ XYZ. Option A is correct.

Express 120 as the product of its prime factors.
Write the prime factors in ascending order.
Answer:
2 x 2 x 2 x 3 x 5
Step-by-step explanation:
The first and smallest prime number that can be divisible by 120 is 2; 120/2 = 60, 60/2 = 30, 30/2 = 15; and the smallest prime number divisible by 15 is 3; 15/3 = 5; and the smallest prime number divisible by 5 is 5; 5/5 = 1.
hence, we have 2 x 2 x 2 x 3 x 5 = 2³ x 3 x 5

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
[tex]\text{A. }\frac{4\sqrt{14}}{{7}}[/tex]
Step-by-step explanation:
In any right triangle, the tangent of an angle is equal to its opposite side divided by its adjacent side. Therefore, we can form a right triangle with non-right angle [tex]\theta[/tex] and its opposite side [tex]\sqrt{7}[/tex] and its adjacent side [tex]5[/tex].
By definition, [tex]\csc \theta=\frac{1}{\sin\theta}[/tex].
In any right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle. To find the hypotenuse, use the Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse, or longest side, of the right triangle and [tex]a[/tex] and [tex]b[/tex] are the two legs of the triangle.
Solving, we get:
[tex]5^2+\sqrt{7}^2=c^2,\\25+7=c^2,\\c^2=32,\\c=\sqrt{32}=4\sqrt{2}[/tex]
Therefore, we have:
[tex]\csc \theta = \frac{1}{\sin \theta}=\frac{1}{\frac{\sqrt{7}}{4\sqrt{2}}},\\\\\csc \theta=1\cdot \frac{4\sqrt{2}}{\sqrt{7}},\\\\\csc \theta =\frac{4\sqrt{2}}{\sqrt{7}}\cdot \frac{\sqrt{7}}{\sqrt{7}}=\boxed{\text{A. }\frac{4\sqrt{14}}{{7}}}[/tex]
Answer: Choice A) [tex]\frac{4\sqrt{14}}{7}[/tex]
======================================================
Explanation:
Refer to the figure below. We start off drawing a right triangle that has opposite side sqrt(7) and adjacent side 5.
This is because tan = opposite/adjacent.
Use the pythagorean theorem to find the hypotenuse is sqrt(32) which simplifies like so
sqrt(32) = sqrt(16*2) = sqrt(16)*sqrt(2) = 4*sqrt(2)
The last thing to do is to take the ratio of the hypotenuse over the opposite side. Recall that csc, aka cosecant, is the reciprocal of sine.
sin = opposite/hypotenuse
csc = hypotenuse/opposite
---------
So we get the following
[tex]\csc{\theta} = \frac{\text{hypotenuse}}{\text{opposite}}\\\\\csc{\theta} = \frac{4\sqrt{2}}{\sqrt{7}}\\\\\csc{\theta} = \frac{4\sqrt{2}*\sqrt{7}}{\sqrt{7}*\sqrt{7}}\\\\\csc{\theta} = \frac{4\sqrt{2*7}}{\sqrt{7*7}}\\\\\csc{\theta} = \frac{4\sqrt{14}}{\sqrt{49}}\\\\\csc{\theta} = \frac{4\sqrt{14}}{7}\\\\[/tex]

Last year, 260 students went to the senior prom at M&T Bank Stadium. This year, the number of students who attended senior prom increased by 9%. How many students attend the senior prom at M&T Bank Stadium this year? Round you answer to the nearest whole number.
Answer:
283 people went this year to the stadium.
Step-by-step explanation:
Let's put this data into pieces so it's less overwhelming.
Last year 260 students went to the prom.
Currently the number of students who attended has increased by 9% from last year.
And the question is asking how many students attended this year?
Well, if this is increasing by 9%, wouldn't we just find 9% of 260 then add it to 260?
0.09 * 260 = 23.4
260 + 23.4 = 283.40. Obviously we can't have 40% of a human being, so let's round it to 283.
which system of equations has infinitely many solutions?
a. 4x+2y=5 -4x-2y=1
b. -10x+y=4 10x-y=4
c. -8x+y=2 8x-y=0
d. -x+2y=6 7x-2y=12
Answer:
None, each of the four given system of equations have only one solution
Step-by-step explanation:
A system of equations have infinitely many solutions, when the equations represent the same line and therefore, the two equations are the same;
Each of the options are examined as follows;
a. 4·x + 2·y = 5...(1)
-4·x - 2·y = 1...(2)
Expressing both equations with y as the subject, we have;
The value of y in equation (1) is given as follows;
4·x + 2·y = 5
2·y = 5 - 4·x
∴ y = 5/2 - 2·x
The value of y in equation (2) is given as follows;
-4·x - 2·y = 1
-2·y = 1 + 4·x
∴ y = -1/2 - 2·x
Therefore, equation (1) and equation (2) represent the same equation and are therefore equal and have only one solution
b. -10·x + y = 4...(1)
10·x - y = 4...(2)
Therefore, we have;
Adding equation (1) to equation (2) gives;
-10·x + 10·x + y - y = 4 + 4
0 + 0 = 8
0 = 8
Given that 0 ≠ 8, equation (1) is not equal to equation (2) and the two equations have only one solution
c. -8·x + y = 2...(1)
8·x - y = 0...(2)
By examination, the values on the left hand side, LHS, of both equations are the same magnitude but opposite in sign, while the right hand side, RHS, of both equations, have different magnitude
Therefore, the two equations are different and have only one solution
d. -x + 2·y = 6...(1)
7·x - 2·y = 12...(2)
Making y the subject of both equations gives;
Equation (1)
2·y = 6 + x
y = 3 + x/2
Equation (2)
2·y = 12 - 7·x
y = 6 - 3.5·x
Therefore, the two equations are different and have only one solution
Answer:
B
Step-by-step explanation:
I'm guessing the answer is B. I know why the other person said all of them only have one solution. But, On b You wrote -10x+y=4 10x-y=4

Find the measure of angle 6.
Answer:
m∠6 = 116°
Step-by-step explanation:
first find x:
7x - 17 = 2x + 78
subtract 2x from both sides: 5x - 17 = 78
add 17 to both sides: 5x = 95
divide by 5: x = 19
plug x into 7x - 17
7(19) - 17 = 116
∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°

◆ x = 145°
Then,
◆ y = x = 145° ( Vertically Opposite angle )
Again,
v + 43° = 180° ( Co - interior angle )
◆ v = 137°
Then,
v + w = 180° (Co - interior angle )

Given:
The function is:
[tex]f(x)=\{(1,0),(2,3),(3,6)\}[/tex]
The given function is:
[tex]f(x)=1-2x[/tex]
The range of this function is [tex]\{-3,-5,-7\}[/tex].
To find:
The range of first function.
The domain of second function.
Solution:
Domain is the set of input or x-values and range is the set of output or y-values.
We have,
[tex]f(x)=\{(1,0),(2,3),(3,6)\}[/tex]
Here, the x-values are 1, 2, 3 and the y-values are 0, 3, 6.
Therefore, the range of the given function is [tex]\{0, 3, 6\}[/tex]. Hence, the correct option is C.
The given function is:
[tex]f(x)=1-2x[/tex] ...(i)
The range of this function is [tex]\{-3,-5,-7\}[/tex].
Putting [tex]f(x)=-3[/tex] in (i), we get
[tex]-3=1-2x[/tex]
[tex]-3-1=-2x[/tex]
[tex]\dfrac{-4}{-2}=x[/tex]
[tex]2=x[/tex]
Similarly,
Putting [tex]f(x)=-5[/tex] in (i), we get
[tex]-5=1-2x[/tex]
[tex]3=x[/tex]
Putting [tex]f(x)=-7[/tex] in (i), we get
[tex]-7=1-2x[/tex]
[tex]4=x[/tex]
The domain of this function is [tex]\{2,3,4\}[/tex]. Hence, the correct option is A.
