Find the equation of the line that passes through (1, -2) and is perpendicular
to the line joining the points (4, 2) and (-1, 7).
O y = -x - 3
O y = -x + 3
O y = -x + 6
O y = x - 3
Answers
Answer:
D. y = x - 3
Step-by-step explanation:
First, find the slope (m) of the line it is perpendicular to using the points of the line, (4, 2) and (-1, 7):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 2}{-1 - 4} = \frac{5}{-5} = -1 [/tex]
Thus, the slope (m) of the line that is perpendicular to the line that runs through (4, 2) and (-1, 7) would be the negative reciprocal of -1.
The slope (m) if the line that is perpendicular to the other line = 1
Thus, substitute m = 1 and (a, b) = (1, -2) into y - b = m(x - a)
y - (-2) = 1(x - 1)
y + 2 = x - 1
Subtract 2 from both sides
y = x - 1 - 2
y = x - 3

Step-by-step explanation:
The fraction is 8/9.
What is Rational Number?Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number.
We have the decimal is 0.8(bar).
let x= 0.888888.... (1)
Now, multiply above equation by 10
10x = 8.8888..... (2)
Subtraction equation (1) and (2), we get
10x - x = 8.8888.... - 0.88888...
9x = 8
x = 8/9
Thus, the fraction is 8/9.

Use the second derivative test to find the relative extrema for f(x)=x^4-2x^2 + 3
Answers
If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:
f'(x) = 4x ³ - 4x
f''(x) = 12x ² - 4
Solve f'(x) = 0 to get the critical points of f(x) :
4x ³ - 4x = 4x (x ² - 1) = 0
→ x = -1, x = 0, x = 1
Check the sign of the second derivative at each of these points:
f'' (-1) = 8 > 0
f'' (0) = -4 < 0
f'' (1) = 8 > 0
These indicate the presence of
• two minima of f (-1) = 2 and f (1) = 2
• one maximum of f (0) = 3
which makes C the correct answer.

The football team has a total of 50jerseys. There are 35 medium sized jerseys. What percent of the jerseys are medium sized jerseys?
Answers
Answer: 70%
Step-by-step explanation:
Total number of jersey = 50.
Total number of medium sized jersey = 35
The percent of the jerseys that are medium sized jerseys will be:
= Number of medium sized / Total number of jersey × 100
= 35 / 50 × 100
= 70%

Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Kai needs to replace the strip laminate that is glued to the vertical faces on a square tabletop. The tabletop is 1.69 m2. What length i laminate does he need
Answers
Area of a square = Side x Side (length x width)
A = 1.69 m²
Length = √area of square
L = √1.69 m²
L = 1.3 m
Check Work: 1.3² = 1.3 m x 1.3m
= 1.69 m²
Answer:
he needs 1.3 meters of laminate for the length
Step-by-step explanation:
area of a square = side multiplied by side (or length x width)
area = 1.69 m²
Length = √area of square
L = √1.69 m² or 1.3m
