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!

A ball is thrown horizontally from the top of
a building 110 m high. The ball strikes the
ground 61 m horizontally from the point of
release.
What is the speed of the ball just before it
strikes the ground?
Answer in units of m/s
The speed of the ball would be 13 m/s just before it strikes the ground.
A ball is thrown horizontally from the top of a 110 m high building. 61 meters horizontally from the moment of release, the ball falls on the earth.
What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
First of all, we get the time of aviation from the vertical component:
Here s = 110 m and g = 9.8 m/s²
s = 1/2 × gt²
Solve for t
t = √(2s/g)
Substitute the values of s = 110 m and g = 9.8 m/s² in the equation,
t = √(2×110/9.8)
t = √22.44
t = 4.7 sec
The horizontal component of velocity is constant :
v = s/t
Here s = 61 m and t = 4.7 sec
v = 61/4.7
v = 12.97 ≈ 13
Therefore, the speed of the ball would be 13 m/s just before it strikes the ground.

For which of the following scatterplots is the correlation between x and y closest to −1 ?
Answer:
Scatter plot attached below.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.
In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
The scatter plot for the correlation between x and y closest to −1 is attached below.

Answer:
[tex]\frac{28}{3}[/tex]
Step-by-step explanation:
When dividing fractions, we must always remember a very important step:
we can multiply the two fractions instead of divide as long as the second fraction must be flipped opposite as a reciprocal.
Let me explain:
When given a simple problem like [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{2}{3}[/tex] , we flip the second fraction (called reciprocal) and multiply it together instead.
[tex]\frac{1}{2} * \frac{3}{2}[/tex]
There, we can just multiply the numerators with each other and the denominators as each other.
1x3=3
2x2=4
Therefore, the answer will be [tex]\frac{3}{4}[/tex].
Similar in this case, we must flip the second fraction and pretend we never even saw a division sign (because who likes dividing anyways?)
[tex]\frac{35}{5}[/tex] ÷ [tex]\frac{-3}{4}[/tex] flip and multiply reciprocal
[tex]\frac{35}{5} * \frac{-4}{3}[/tex]
[tex]\frac{140}{15}[/tex] simplify
[tex]\frac{28}{3}[/tex] final answer!

A triangle has one leg of 24 inches and one leg of 10 inches. For the triangle to be a right triangle, what must be the length of the hypotenuse
Answer: 26 inches
Step-by-step explanation:
The hypoteneuse is the longest side in a triangle. From the question, we are already informed that a triangle has one leg of 24 inches and one leg of 10 inches.
To calculate the hypotenuse, we add the square of both legs together which are the opposite and adjacent and then find the square root. This will be
hypotenuse² = 24² + 10²
hypotenuse² = 576 + 100
hypotenuse² = 676
hypotenuse = ✓676
hypotenuse = 26
The hypothenuse is 26 inches

Answer:
[tex]x=\dfrac{-(-15)\pm\sqrt{(-15)^2-4(-2)(-3)} }{2(-2)}[/tex]
Step-by-step explanation:
Given equation: [tex]-2x^2 - 11x + 7 = 10 + 4x[/tex]
First, rearrange the equation so that it is in the general form of [tex]ax^2+bx+c=0[/tex]
[tex]-2x^2 - 11x + 7 = 10 + 4x[/tex]
Subtract 4x from both sides:
[tex]-2x^2 - 15x + 7 = 10[/tex]
Subtract 10 from both sides:
[tex]-2x^2 - 15x - 3 = 0[/tex]
Therefore,
[tex]a=-2[/tex][tex]b=-15[/tex][tex]c=-3[/tex]Input these values into the quadratic formula:
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

Write the equation, in standard form, of the line passing through (0,-8) with a slope of -1/2
Answer:
The answer is
[tex] \huge \boxed{y = - \frac{1}{2} x - 8 }[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (0,-8) and slope - 1/2
We have
[tex]y + 8 = - \frac{1}{2} (x - 0) \\ y + 8 = - \frac{1}{2} x \\ y = - \frac{1}{2}x - 8[/tex]
We have the final answer as
[tex]y = - \frac{1}{2} x - 8 \\ [/tex]

Angelo, age 40, is comparing the premium for a $125,000 whole life insurance policy he may take now and the premium for the same policy taken out at age 45. the annual life insurance premium (per $1000 of face value) for a 40-year-old male is 22.60 and for a 45-year-old male is 27.75. what would be the difference in total premium costs over 20 years for this policy at the two age levels? a. $69,375 b. $11,725 c. $12,875 d. $644
The difference in total premium costs over 20 years at the two age levels is $12875.
What is face value?Face value is a term used to describe the nominal value of a security, as stated by its issuer.
Let us consider the entire scenario for a 40-year old male.
Annual life insurance premium per 1000 of face value = $22.60
So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 22.60 = $2825.
For 20 years the premium will be = 2825*20 = $56500
Let us consider the entire scenario for a 45-year old male.
Annual life insurance premium per 1000 of face value = $27.75
So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 27.75 = $3468.75
For 20 years the premium will be = 3468.75*20 = $69375
The difference in total premium costs over 20 years = 69375-56500 The difference in total premium costs over 20 years = $12875
Therefore, The difference in total premium costs over 20 years at the two age levels is $12875.

Find the slope of the equation that goes through:
(-4,-14) and (-10,6)
Hello.
In order to find the slope of the given line, we should use the slope formula:
[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1}}[/tex]
y₂= the y-coordinate of the second point (6
y₁= the y-coordinate of the first point (-14)
x₂=the x-coordinate of the second point (-10)
x₁=the x-coordinate of the first point (-4)
Let's plug in the values and solve:
[tex]\mathrm{\displaystyle\frac{6-(-14)}{-10-(-4)}=\frac{6+14}{-10+4} =\frac{20}{-6} =-\frac{20}{6} =-\frac{10}{3} }[/tex]
