Answer:
B. The triangle in question may or may not be a right triangle
Step-by-step explanation:
The length of the third side of the triangle may have any measure between 0 and 2. The triangle will only be a right triangle if the third side has length √2.
The triangle may or may not be a right triangle.

Answer:
65 degrees
Step-by-step explanation:
Since it is given that AB=DC
then we know that AO=DO and BO=CO because it is the radius of a same circle.
Hence the shapes are equal and thus DOC=65 degree as it serves as a corresponding angle to AOB

Alicia borrowed $15,000 to buy a car. She borrowed the money at 8% for 6 years
Answer:
She have to pay the bank at the end of the 6 years = 222000$
Step-by-step explanation:
Formula applied in this case where price, interest rate and time duration is mentioned.
Interest = prt/100
Substituting all the given values in the formula.
interest = 15000 * 6 * 8/100
150 * 6 * 8 = 7200
Interest + 15000 = 15000 + 7200 = 222000$ has to pay the total.
In this question amount is 15000 multiply by 6 and by 8 then divide it by 100 so we get the interest then we add it in to amount so we get an answer that is total amount which he has to pay. Hope this helps! :P PLZ GIVE ME BRAINLIST
Construct an equation that has y = 8 as its solution. Use y on both sides of the equation.
Answer:
3y + 4 = 20 + y
Step-by-step explanation:
The equation that has y = 8 as its solution will be 3y + 4 = 20 + y.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that Construct an equation that has y = 8 as its solution. The equation of the line will be:-
3y + 4 = 20 + y.
When we solve the equation we will get the value of y equal to 8.
3y + 4 = 20 + y.
3y - y = 20 - 4
2y = 16
y = 16 / 2
y = 8
Therefore, the equation that has y = 8 as its solution will be 3y + 4 = 20 + y.

A family wants to purchase a house that costs $120,000. They plan to take out a $100,000 mortgage on the house and put $20,000 as a down payment. The bank informs them that with a 15-year mortgage their monthly payment would be $745.86 and with a 30-year mortgage their monthly payment would be $546.01. Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage.
9514 1404 393
Answer:
$62,308.80
Step-by-step explanation:
The total amount paid on the 15-year mortgage is ...
($745.86/mo)×(12 mo/yr)×(15 yr) = $132,254.80
The total amount paid on the 30-year mortgage is ...
(546.01/mo)×(12 mo/yr)×(30 yr) = $196,563.60
__
The amount saved by selecting the 15-year mortgage is the difference of these amounts:
$196,563.60 -132,254.80 = $62,308.80
_____
Additional comment
This problem statement has several numbers in it that are irrelevant to the question being asked. This is why you need to read and understand the given information, and also understand the question being asked.
Here, the total cost of the house will include the mortgage cost and the down payment. The down payment is the same in either case, so does not factor in when we subtract one total cost from the other. Any difference in cost is due only to the difference in loan cost.

the area of a 20 cm wide rectangle is 500 cm cm2 what is the length?
Given = b = 20cm, A = 500cm2 l=?
A = l×b,
500= l×20
l= 25
THE LENGTH IS 25 CM
Answer:
25 cm
Step-by-step explanation:
area of a rectangle = length × breadth
500 = length × 20
500/ 20 = length
25 = length
therfore, the length of the rectangle is 25 cm
Evaluate the inverse trigonometric function Sin^-1(-1). Give answers in both radians and degrees.
A) Sin^-1(-1) = -pi or -180°
B) Sin^-1(-1) = 3pi/2 or 270°
C) Sin^-1(-1) = pi or 180°
D) Sin^-1(-1) = -pi/2 or -90°
Answer:
B) Sin^-1(-1) = 3pi/2 or 270°
D) Sin^-1(-1) = -pi/2 or -90°
Step-by-step explanation:
Sine function:
The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.
Inverse sine:
The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.
Sin^-1(-1)
Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.

Help me I need help plsss
Answer:
B and F
Step-by-step explanation:
Given
Functions A and B
Required
Select the true statements
First, determine the equation of A
We have:
[tex](x_1, y_1) = (1,2)[/tex]
[tex](x_2, y_2) = (3,10)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{10 - 2}{3 - 1}[/tex]
[tex]m = \frac{8}{2}[/tex]
[tex]m =4[/tex]
So, the equation is:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 4(x - 1) + 2[/tex]
[tex]y = 4x - 4 + 2[/tex]
[tex]y = 4x -2[/tex]
So, we have:
[tex]y = 4x -2[/tex] ------ A
[tex]y = 3x + 4[/tex] ---- B
The y intercept is when [tex]x = 0[/tex]
So, we have:
[tex]y = 4 * 0 - 2 = -2[/tex] ---- y intercept of A
[tex]y = 3 * 0 + 4 = 4[/tex] ---- y intercept of B
By comparison:
[tex]-2 < 4[/tex]
Hence: (b) is correct
The rate of change of a function [tex]y = mx + b[/tex] is m
So:
The rate of change of A is:
[tex]m_A=4[/tex]
and for B is:
[tex]m_B=3[/tex]
By comparison:
[tex]4 > 3[/tex]
Hence: (F) is correct

Chicago Cubs lost 4 games and won the
others. What percent of the games have
they won?
The percentage of the games the club has won is P = 77.78 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the total number of games = 18
The number of games they lost = 4
So , the number of games they won = 14 games
Now , the percentage of games they won = ( 14 / 18 ) x 100
On simplifying the equation , we get
A = 0.7778 x 100
A = 77.78 %
Hence , the percentage is 77.78 %

Multiply both sides of the equation by 5.
5 · [tex]\frac{1}{5}[/tex] · [tex](2x+10)=[/tex] 5 · 4

bracelet. Let the price of the bracelet be $x.
(i) Express the price of the necklace in terms of x.
Answer:
The necklace is 4x.
Step-by-step explanation:
If the bracelet is x and the necklace is 4 times greater you would multiply the cost of the bracelet by 4. Meaning it would be X *4= 4x (x multiplied 4 times.)

The 95% confidence interval does not mean that b. If you add and subtract two standard errors to ... 95% of all cases,... captured the true population mean.
What is the 95% confidence interval for a population mean?It means that for any given number of samples, 95% of them will fall within 2 standard errors of the true mean of the population the sample is derived from.
Applying this confidence interval to the sample mean will not help you capture the true population mean which is why option B is incorrect as regards the 95% confidence interval for the population mean.
