Answer:
To find : If 21m, 28m and 49m form a right angle or not.
Logic : To find if this triangle is a right angle, we can use the Pythagoras Theorem, which states that the square if the longest side should be equal to the square of the sum of the other two sides.
The name of the longest side is called the hypotenuse, while the others are called legs or one is the perpendicular and the other the base.
Proof : [tex]h^{2} = p^{2} + b^{2}[/tex]
=> [tex]49^{2} = 28^{2} + 21^{2}[/tex]
=> 2401 = 784 + 441
=> 2401 ≠ 1225
Therefore these side lengths cannot be the lengths of a right angled triangle.

The graph of y = 4 – StartRoot 2 x EndRoot is shown.
On a coordinate plane, a curved line approaches the grid line at (3, 1.5) and ends at (0, 4).
Which statement about the graph is accurate?
The x-intercept of the graph is (4, 0).
The graph has no y-intercepts.
The maximum of the graph occurs at the y-intercept.
The minimum of the graph occurs at the x-intercept.
Answer:
A
Step-by-step explanation:
Answer:
C (third option) The maximum of the graph occurs at the y-intercept.
Step-by-step explanation:
We will use the process of elimination
It’s not option 1 because if you graph it using the graphing calculator you can see that the x intercept is 8,0 not 4,0
It’s not option 2 because you can see the y intercept is at 0,4 which means there is a y intercept
It’s not option 4 because the graph continues down even after the x intercept
Which leaves us with option 3

The point Q (5,3) is translated 2 units left. What are the coordinates of the resulting point Q
Answer:
(3,3)
Step-by-step explanation:
Since it's to the left, and not up or down at all, the y-value does not change. The x-value, however, is affected. Since it's to the left, it is decreasing in value by 2 points. If it were to the right, it would increase in value to (7,3), since it'd be going further away from (0,0).
Answer:
Q = (3,3)
Step-by-step explanation:
Moving the point left moves the x value down 2.
5-2=3
Therefore, Q = (3,3)
What is the equation of the line that goes through the points 2,9 and 3,1
The equation of the line that goes through the given points is y = -8x + 25.
Given the following points:
Points on the x-axis = (2, 3)Points on the y-axis = (9, 1)To determine the equation of the line that goes through the given points:
First of all, we would determine the slope of this line by using the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the points into the formula, we have;
[tex]Slope, \;m = \frac{1 - 9}{3 - 2}\\\\Slope, \;m = \frac{-8}{1}\\\\[/tex]
Slope, m = -8
Now, we can determine the equation of the line by using this formula:
[tex]y-y_1 =m(x-x_1)\\\\y-9=-8(x-2)\\\\y-9=-8x+16\\\\y=-8x+16+9[/tex]
y = -8x + 25

A number n square plus 12 is the same as the
quotient of p and 4.
Answer:
n² + 12 = p/4
or
n² + 12 = p ÷ 4
Step-by-step explanation:
The number n is squared, and you have to add 12 to complete the equality. So n squared plus 12 will equal p divided by 4.
If x + 3 = 10, then x = 7. What is the hypothesis and the conclusion?
Answer:
10 = 10
Step-by-step explanation:
x + 3 = 10
Substitute 7 in for x
7 + 3 = 10
Add
10 = 10
Answer: no wrong cause in order to get 7 as x=7 you need to do x+2=10 cause x+3=4 so that would be wrong
Step-by-step explanation: x=3=10 x=7

How do you know if a girl like you and what is x+10 divided by 6 = 1
Answer:
x = -2/3
Step-by-step explanation:
x + 10 ÷ 6 = 1
Divide
x + 1 2/3 = 1
Subtract 1 2/3
x = -2/3
Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.

Jose borrowed $1500 from the bank at a rate of 8% simple interest per year. He paid
in interest in three years.
Answer:
360
Step-by-step explanation:
Jose will $360 in interest in three years.
What is simple interest?Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
Now it is given that,
Principle amount, P = $1500
Rate of interest, R = 8% = 0.08
Time, T = 3 years
Now, since the simple interest paid in T years is given as,
S.I = PRT/100
S.I = 1500*8*3/100
S.I =36000/100
S.I = 360
Simple interest paid in 3 years is $360.
Hence,Jose will $360 in interest in three years.

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
Answer:
38.28
Step-by-step explanation:
ok so one of the sides don't count because the circle is there. so that leaves us with 14 + 14 + 4= 32(my bad)
then the circumference is for half the circle. and when finding the circumference you use radius so 2 cm. 2 x 3.14 x 2 = 12.56
then divide it by 2- 6.28
so that gives us 38.28
