given cot A= 40/9 and that angle A is in quadrant 1 find the exact value of sec A in the simplest radical form using a rational denominator
Answer:
41/40Step-by-step explanation:
Given cotA = 40/9
1/tanA = 40/9
tanA = 9/40
According to SOH, CAH, TOA
tan A = 9/40 = opposite/adjacent
Get the hypotenuse
hyp² = opp²+adj²
hyp² = 9²+40²
hyp² = 81+1600
hyp² = 1681
hyp = √1681
hyp = 41
Het sec A
sec A = 1/cosA
Since cos A = adjacent/hypotenuse
cos A = 40/41
secA = 1/(40/41)
SecA = 41/40
Hence the exact value of secA is 41/40

A cylinder has a radius of 7 inches and a height of 20 inches. Which is closest to the surface area of this cylinder?
517 sq in.
769 sq in.
1,187 sq in.
3,077 sq in.
Answer:
1,187 (It is the closest)
Step-by-step explanation:
Formula: 2πrh+2πrr
Equation: 2x3.147x20 + 2x3.14x7x7
Solution:879.2 + 307.72=1,186.92
The surface area of the cylinder with a radius of 7 inches and a height of 20 inches is closest to 1,187 square inches.
What is a Cylinder?A cylinder is a three dimensional geometric figure on which there are two identical circular bases which are parallel to each other located within a distance. This distance is called the height of the cylinder and the radius is the radius of this circle.
Axis of cylinder is the line segment connecting the center of two circular bases.
Here, we have to find the surface area of the cylinder.
Height of the cylinder = 20 inches
Radius of the cylinder = 7 inches
Surface Area of the cylinder = 2πr (h + r), where h is the height of the cylinder and r is the radius of the cylinder.
Surface Area = 2π × 7 (20 + 7)
= 2π × 7 × 27
= 2π × 189
= 378π
= 378 × 3.14
= 1186.92 ≈ 1187
Hence the surface area of this cylinder is closest to 1187 square inches.

Answer:
G (-2, -3) is in the solution set
Step-by-step explanation:
Finding the solution set
You are given the boundary lines for the inequalities, but the graph does not show the solution set.
The line for inequality y < -2x -4 is the one with negative slope that extends from upper left to lower right. The relation of y to the comparison symbol is ...
y <
indicating that y-values in the solution set will be less than those on the line. The line itself is NOT included in the solution set. That is, "shading" will be below and left of the line.
__
The line for inequality 2x - 4y ≤ 8 is the one with positive slope. Considering the variable with the positive coefficient, its relation to the comparison symbol is ...
x ≤
indicating that x-values in the solution set will be less than (or equal to) those on the line. The line IS included in the solution set. Shading will be above and left of the line with positive slope.
Then the doubly-shaded area is the quadrant at the left side of the X where the lines cross. The lower boundary of that is included in the set, while the upper boundary is not.
__
Considering the points
Now that you know the location of the solution set, you can decide whether any given point is in it, or not.
Plotting the points, you find that F and G are on the boundary lines, and H and J are outside the solution set. Point F(-2, 0) is on the upper boundary line, so is not in the solution set, either.
The point listed in choice G, (-2, -3) is in the solution sets of both inequalities.

For which valies of A, B, and C will Ax + By = C be a horozontal line through the point (-4, 2)?
Answer: B=1, C=2 and A =0.
Step-by-step explanation:
On a coordinate plane , a horizontal line is parallel to x-axis with 0 slope(m) .
Every horizontal line is written as y=c [∵ y= mx+c , here m=0 ]
Here value for x changes but values for y is fixed as c.
If the horizontal line passes through (-4,2), so for some point x= -4 and y=2.
So, Equation of line must be y=2, which can be written as (0)x+(1)y =2
By comparing this to Ax + By = C, we get B=1, C=2 and A =0

Answer:
in slope intercept form it would be y = -x + 4

subtract 2x from both sides: 2y = -2x + 8
divide both sides by 2: y = -x + 4

Docs cookie recipe calls for 3 cups of sugar and 2 cups of flour. how many cups of sugar needed for 14 cups of flour?
Answer:
21 cups of sugar
Step-by-step explanation:
so it gives you the ratio for cups of sugar(or as i'm going to use it, COS) and cups of flower(COF), which is 3:2, so if you have 14 cups of flower, you would divide 14 by the COF part of the ratio, which is 2, which gives you 7, then you would multiply the COS part of the ratio, which is 3, by 7 to get the number of cups of sugar needed for 14 cups of flower.

Henry has 96 marbles. He is packing containers with 8 marbles in each container. How many containers, c, does Henry need to pack all the marbles?
96 − c = 8
96 = 8 x c
c = 96 + 8
8 ÷ c = 96
Answer:
96 = 8 times c
Step-by-step explanation:
96 divided by 8 = 12
12 times 8 = 96
BRAINLIEST PLEASE
The number of containers, c, that Henry needs to pack all the marbles will be B. 96 = 8 x c.
Since Henry has 96 marbles and is packing containers with 8 marbles in each container, the equation to solve the number of containers needed will be;
96 = 8 x c.
96 = 8c
c = 96/8
c = 12
Therefore, 12 containers will be needed.

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence
pragnesh and roghui = [tex]\frac{1}{3}[/tex]
qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence
time taken when they all work together
= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]
= [tex]\frac{13}{12}[/tex]
= [tex]\frac{12}{13}[/tex]
