What is the equation of the line that is perpendicular to y equals negative four x plus five and passes through the point four comma negative three ?
Answer:
y= 1/4x - 4
Step-by-step explanation:
use point slope form which is:
y - y1 = m(x - x1)
we know that the slope will be 1/4 because perpendicular is a negative reciprocal.
plug everything into point slope form:
y + 3 = 1/4 ( x - 4)
we distribute the 1/4 and then subtract the three and we get our answer
y= 1/4x - 4

USING STRUCTURE An athletic facility is building an indoor track. The track is composed of a rectangle and two semicircles, as shown. A drawing shows an indoor track. It is shaped like a rectangle with a semi-circle on each of the shorter sides. The length of the rectangle is labeled x. The radius of each semi-circle is labeled r. A. Write a formula for the perimeter of the indoor track. $P=$ b. Solve the formula for $x$ . $x=$ Question 2 c. The perimeter of the track is 660 feet, and $r$ is 50 feet. Find $x$ . Round your answer to the nearest foot. $x=$ feet
Answer:
Step-by-step explanation:
Find the digram attached.
Perimeter of the track = perimeter of the rectangle + perimeter of the 2semicircles
Perimter of a rectangle = 2(x+r) where:
x is the length
2r is the width of the rectangle = diameter of the semicircle
Perimeter of semicircle = 2πr/2 = πr
Perimeter of 2semicirle = 2πr
Perimeter of the track = 2(x+2r) + 2πr
r is the radius if the semicircle
Expand
Perimeter of the track = 2x+4r + 2πr
Perimeter of the track = 2(x+2r+πr)
b) Given P = 2(x+2r+πr), we are to make x the subject of the formula.
P = 2x+4r+2πr
P-4r-2πr = 2x
Divide both sides by 2.
(P-4r-2πr)/2 = 2x
x = (P-4r-2πr)/2
c) Given
P = 600fr
r = 50ft
x = (600-4(50)-2π(50))/2
x = (600-200-100(3.14))/2
x = 400-314/2
x = 86/2
x = 43ft
Hence the value of x to nearest foot is 43ft

Consider the function represented by the equation y-6x-9 = 0. Which answer shows the equation written in function
notation with x as the independent variable?
O F(x) = 5x + 9
O f(x) = 1/3 x + 2 / 2
Of) = 5y+9
O fox = 1/3 + 2 / 2
Answer:
f(x) = 5x+9
Step-by-step explanation:
This meets the criteria:
function notation - all this means is replace the'y' with 'f(x)
x as the independent variable - basically means don't change the letter for x

Simplify. 4√−99
Enter your answer, in simplest radical form, in the box.
Answer:
Not sure on this but I'm pretty sure its 12i√11 since you have to use an imaginary number in order for the equation to work.
By simplifying the expression 4√−99, we have; 12i√11.
To simplify 4√−99, we first need to simplify the number present within the square root.
To do this, the factors are determined as follows;
4 × √9 × √-11We can therefore find the square root of 9 so that we have;
4 × 3 × √-11.4 × 3 × √-1112 × √-11Furthermore, √-11 can be rewritten as;
√-1 × √11.However, in complex numbers, √-1 = i.
Ultimately, we have 12i√11 as the simplification of 4√−99.

Answer:
18.6667 = w
9.3333 = l
ITS WRONG
IT'S WRONG
WRONG ANSWER
Step-by-step explanation:
w-6 = l
w=w
Act like it is a rectangle, two lengths, and two sides.
w-6 + w-6 + w + w = 44
w-12 + 2w = 44
3w - 12 = 44
add 12 to both sides
3w=56
divide both sides by 3
18.6667 = w

The second term in the sequence is 17.
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
Given the nth term of a sequence to be b(n)=b(n-1)+1, where n is the number of terms of the sequence
If b(1) = 16... (1)
The second term of the sequence is generated for n= 2:
b(n)=b(n-1)+1
b(2)=b(2-1)+1
b(2) = b(1)+1... (2)
Substituting equation 1 into 2
b(2) = b(1)+1
b(2) = 16 + 1 = 17
Hence, The second term in the sequence is 17.
