The sum of the squares of two consecutive integers is 145. Find the two integers.
Please help asap .
Answer: The two integers are 8 and 9.
Step-by-step explanation: Let n represent the number.
n^2 + (n + 1)^2 = 145
By foiling, this can be rearranged to:
n^2 + n^2 + 2n + 1 = 145
Subtract 145 from both sides:
2n^2 + 2n - 144 = 0
Divide both sides by 2:
n^2 + n - 72 = 0
Factor the polynomial:
(n + 9)(n - 8) = 0
Solve for n:
n = -9, n = 8
Since they need to be consecutive, make the 9 positive. It will be positive either way because it is being squared.
Now, n = 9 and n = 8.
These are your two integers. Hope this helps!

Write the equation of a line that is perpendicular to y = -3 + 6 and that passes through the point
(2,-6).
Answer:
Perpendicular lines are lines that are at right angles to each other.
For perpendicular lines, the product of their slopes is -1.
[tex]\implies m_2=\dfrac{-1}{m_1}[/tex]
(where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of perpendicular lines)
The slope of the given equation is -3. Therefore, to find the slope of the line that is perpendicular:
[tex]m_2=\dfrac{-1}{-3}=\dfrac13[/tex]
Now we have the slope, we can use the point-slope form of a linear equation with [tex]m=\dfrac13[/tex] and [tex](x_1,y_1)=(2,-6)[/tex] to find the equation of the perpendicular line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-6)=\dfrac13(x-2)[/tex]
[tex]\implies y+6=\dfrac13x-\dfrac23[/tex]
[tex]\implies y=\dfrac13x-\dfrac{20}3[/tex]

Work out the area of the triangle. Give your answer to 1 decimal place. 10cm, 13cm sides. Angle 105
Answer:
62.8
Step-by-step explanation:
So, keep in mind that the area of a triangle is equivalent to: 1/2(b)(h) with b being your base and h being your height.
We have our base: 10, and our angle: 105. Now we need to find our height. You don't just have to look at a triangle the way that it's oriented in the problem. Rotate it so that 10cm is at the bottom, and it will be much easier.
From there, you can create a right triangle and draw a line from the top of the triangle straight to the base. Then, you have a right triangle, where you can solve the height, and then plug your answer into the area formula. Further steps are detailed in the picture.
Wendy asked 40 students on the school football team if they ever injured themselves while playing sports. Fifteen football team members responded “Yes.” Wendy concluded that 375 of the 1,000 students in her school have injured themselves playing sports. Select whether Wendy's conclusion is valid or invalid.
Answer:
Yes, Wendy's conclusion is valid.
Step-by-step explanation:
40 divided by 15= 2.666666666666667
Therefore, 1000 divided by 2.666666666666667= 374.999999999999953 which can be rounded to 375

what is the value of x
Answer:
x = 20
Step-by-step explanation:
given a line parallel to a side of a triangle and intersecting the other two sides, then it divides those sides proportionally , that is
[tex]\frac{10}{5x+10}[/tex] = [tex]\frac{11}{121}[/tex] = [tex]\frac{1}{11}[/tex] ( cross- multiply )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20

What is a box plot?A box plot provides the summary of a data using the five number summary that is minimum, lower quartile, median, upper quartile and maximum.
From the diagram, the third quartile is 54 years. Hence 75% of the employees are between 35 to 57 years.
25% are older than 54 years, hence:
Employers older than 54 years = 25% of 23 employees = 5.75

Three side lenghts of 5.2,6.3, and 10.5 units will form exactly one unique triangle
True, the three sides will form exactly one unique triangle.
What is a triangle?A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.
let the first length = alet the second length = blet the third length = k(b - a) < k < (b + a)
(6.3 - 5.2 ) < k (6.3 + 5.2 )
1.1 units < k < 11.5 units
The third length = 10.5 units which is greater than 1.1 units and less than 11.5 units.
Thus, the three sides will form exactly one unique triangle.

Find the minimum value of the parabola y = x2 – 2x – 3.
Answer:
- 4
Step-by-step explanation:
the minimum value of the parabola is the value of the y- coordinate of the vertex.
given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² - 2x - 3 ← is in standard form
with a = 1 and b = - 2 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{2}[/tex] = 1
substitute x = 1 into the equation for corresponding y- coordinate
y = 1² - 2(1) - 3 = 1 - 2 - 3 = - 4
then minimum value is - 4

20. Olivia translated triangle DEF 4 units vertically to form triangle GHJ.
If Olivia performed the translation correctly, what is the measure of angle H?
O 17.5°
O 43.0°
O 32.5°
O 28.0°
Answer:
Step-by-step explanation:
m∠E = m∠H
( 3x - 20 )° = ( x + 15 )°
3x - 20 = x + 15
3x - x = 15 + 20
2x = 35
x = 17.5
m∠H = 3(17.5) - 20 = 32.5 °
