if a+b=10 and a-b=6,then find the value of (a²+b²)
Answer:
68
Explanation:
Sets of equations:
1) a + b = 10
2) a - b = 6
Make 'a' the subject:
1) a = 10 - b --- equation 1
2) a = 6 + b --- equation 2
Solve them by substituting:
⇒ 10 - b = 6 + b
⇒ -b - b = 6 - 10
⇒ -2b = -4
⇒ b = 2
Find value of 'a', a = 10 - b, a = 10 - 2 = 8
Then find (a²+b²), by inserting a = 8, b = 2,
⇒ ((8)²+(2)²) = 64 + 4 = 68
Step-by-step explanation:
given,
a+b=10.............( eqn 1)
a-b=6................(eqn 2)
adding eqn1 and eqn2
a+b=10
a-b=6
______
2a=16
a=16/2
a=8
putting the value of a in eqn 1
a+b=10
8+b=10
b=10-8
b=2
now,
(a²+b²)= 64+4=68
A line passes through the point (-2, -9) and has a slope of 8
Step-by-step explanation:
[tex]y - y_1 = m.(x - x_1)[/tex]
[tex]y - ( - 9) = 8.(x - ( - 2))[/tex]
[tex]y = 8x + 16 - 9[/tex]
[tex]y = 8x + 7[/tex]
Answer:
y = 8x + 7
Step-by-step explanation:
We are given that a line contains the point (-2, -9), and a slope of 8
We want to write the equation of this line
There are multiple ways to write the equation of the line:
Slope-intercept form, written as y=mx+b where m is the slope and b is the y interceptStandard form, written as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be zero and a cannot be negativePoint-slope form, written as [tex]y-y_1=m(x-x_1)[/tex], where m is a slope and [tex](x_1, y_1)[/tex] is a pointThe most common of these 3 methods is slope-intercept form, so let's write our equation this way
As we are already given the slope, we can immediately plug that into our formula for m
Replace m with 8:
y=8x+b
Now we need to find b
As the equation passes through (-2, -9), we can use its values to help solve for b
Substitute -2 as x and -9 as y:
-9 = 8(-2) + b
Multiply
-9 = -16 + b
Add 16 to both sides
7 = b
Substitute 7 as b.
y = 8x + 7

Hayden said the expression 3(2x+1) will always be greater than 3 because when I distribute the 3 to the numbers inside the parentheses, I will multiply 3 and 1 which is 3 since I will always be adding to the first part of the expression the final answer must be greater than 3
Answer:
9x.Step-by-step explanation:
Hayden is correct. 3(2x + 1) = 9x.
Here is explanation:
If you didn't know, 2x + 1 would simply be 3x.
So then, 3 * 3x would then be 9x.

The price of a certain computer stock t days after it is issued for sale is p ( t ) = 100 + 20t − 3t^2 dollars. The price of the stock initially rises, but eventually begins to fall. During what period of time does the stock price rise? 0 ≤ t ≤ If you owned the stock, after how many days would you sell it? days
The period of time does the stock price rise is 0 ≤ t ≤ 10/3.
It would sell in 3.34 days.
What is differentiation?It is the process of finding the derivative, or rate of change, of a function.
The price of a certain computer stock after t days is
p(t) = 100 + 20t - 3t²
Now, take the derivative of the given function and equate it to zero to find the critical points,
p'(t) = 20 - 6t = 0
t = 20/6
t = 10/3 days
Thus, there are two intervals in which the given function is defined
(0, 10/3) and (10/3, ∞)
For the interval (0,10/3 ),
p'(1) = 20 - 6(1) =14
For the interval (10/3, ∞),
p'(2) = 20 - 6(2) = 8
Since p'(t) in the interval (0, 10/3) indicates that the function is increasing.
0 < t <10/3
Since at the point t = 3.34 days it would sell.

Step-by-step explanation:
To solve the area of the prism we have to multiply the area of the base * the height of the prism. The base of the prism is a right triangle.
(b*h)÷2 = Area of a triangle
Base = 4
Height = 3
Now:
(4*3)/2 = 6 miles²
Now we have to multiply 6 miles² by 5 as our height.
We get 30 miles² as the volume of the figure.

The probability of winning a prize is 0.929 if Michiko is selling raffle tickets to raise money for the school band. The odds against winning a prize in the raffle are 13:1 option first is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The odds against winning a prize in the raffle are 13:1
This means 13 to 1 odds for winning:
The probability of winning a prize:
Winning = 13/(13+1) = 0.929 or
=92.8571%
Losing = 1 - 0.9286 = (0.0714) or
=7.14%

Isabel works for a company that makes toys. She is trying to figure out what types of toys kids enjoy playing with most. She started with a survey asking whether kids liked dolls or trains. She surveyed 80 kids. Of the kids who don't like dolls, 30% more kids like trains than don't like trains. Fill out the rest of his table.
The table that represents the survey conducted by Isabel is:
Like Dolls Don't like Dolls Total
Like Trains 40 15 55
Don't like Trains 17 8 25
Total 57 23 80
How can the table be filled?The total number of kids that like dolls = total number kids - total number of kids that don't like dolls
80 - 23 = 57
Number of kids that don't like Trains but like dolls = total number kids that like dolls - Number of kids that like Trains and dolls
57 - 40 = 17
Number of kids that don't like dolls and but like trains :
30% x 23 = 7
(23 - 7) /2 + 7 = 15
Number of kids that don't like dolls and trains = (23 - 7) / 2 = 8

What is the mean absolute deviation of 4,6,7,10,13
Answer:
2.8
Step-by-step explanation:
To find the mean aboslute deviation, you first need to find the mean:
(4 + 6 + 7 + 10 + 13)/5 = 8
Then, subtract the mean from each value, and take the abosulte value. Absolute value is essentially the same number, but if it is negative, make it positive.
4 - 8 = -4 = 4
6 - 8 = -2 = 2
7 - 8 = -1 = 1
10 - 8 = 2 = 2
13 - 8 = 5 = 5
Then, take the mean of all of these values:
(4 + 2 + 1 + 2 + 5)/5 = 2.8

How to solve the question?In the question, we are asked to find the area of the given shapes.
Figure a:-
It is showing a triangle.
The area of a triangle is calculated using the formula:
Area = (1/2)*Base*Height.
Thus, the area of the triangle
= (1/2)*7*3.8 sq. km
= 13.3 sq. km.
Figure b:-
It is showing a rectangle.
The area of a rectangle is calculated using the formula:
Area = Length*Width.
Thus, the area of the rectangle
= 8.2*7 sq. cm
= 57.4 sq. cm.
Figure c:-
It is showing a parallelogram.
The area of a parallelogram is calculated using the formula:
Area = Base*Height.
Thus, the area of the parallelogram
= 9.1 * 5 sq. km
= 45.5 sq. km.
Figure d:-
It is showing a trapezoid.
The area of a trapezoid is calculated using the formula:
Area = (1/2)*(Sum of parallel sides)*(height).
Thus, the area of the trapezoid
= (1/2)*(2.7 + 8.9)*4.2 sq. m.
= 11.6 * 2.1 sq. m.

In this question we are provided with right angle triangle having hypotenuse ( longest side ) = c , perpendicular = 5 and base = 12 . And we are asked to find the length of missing side i.e. hypotenuse and if necessary we have to round it off to 2 decimal places.
We can find the missing side by using Pythagorean Theorem . It states that sum of squares of perpendicular and base is equal to square in a right angle triangle that is ,
[tex] \: \qquad \: \qquad \: \underline{\boxed{ \frak{H {}^{2} = P {}^{2} + B {}^{2} }}}[/tex]
Where ,
H refers to HypotenuseP refers to PerpendicularB r refers to BaseSOLUTION : -
Substituting value of hypotenuse as c , perpendicular as 5 and base as 12 in formula :
[tex] \quad \longmapsto \qquad \: (c) {}^{2} = (5) {}^{2} + (12) {}^{2} [/tex]
Squaring 5 and 12 :
[tex] \quad \longmapsto \qquad \:(c) {}^{2} = 25 + 144[/tex]
Adding 25 and 144 :
[tex] \quad \longmapsto \qquad \:(c) {}^{2} = 169[/tex]
Applying square root to both sides :
[tex] \quad \longmapsto \qquad \: \sqrt{(c) {}^{2} } = \sqrt{169} [/tex]

Step-by-step explanation:
Every variable has a coefficient. That’s the number it is multiplied by. According to mathematical convention, coefficients always go in front of their variable. If there is no number in front of a variable in an expression, the coefficient is 1 since the product of any number and 1 is that number. In expressions, operations can be applied directly to a variable. Here are some examples: What is the coefficient of the variable in the expression ½ + v - 3?
Answer:
1
Step-by-step explanation:
Answer:
There is only 1 variable and it is v.
There is no coefficient.
That means the coefficient is 1.
The coefficient of the variable in the expression ½ + v - 3 is [tex]\frac{1}{2}[/tex]
What is the coefficientIn mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression (including variables such as a, b, and c). When the coefficients are themselves variables, they may also be called parameters.
Given that,
