Find the missing coefficient in the equation of the line that passes through the given point.5.) Ax + y = 3;(2,-5)

6.) 3x + By= -1;(2, 7)

Help!! Please

Answers

Answer 1

Answer:

Answer:

5) A = 4

6) B = -1

Step-by-step explanation:

Question 5

Substitute (2, -5) into the equation to find the missing coefficient

A(2) + (-5) = 3

2A - 5 = 3

2A = 8

A = 4

Question 6

Substitute (2, 7) into the equation to find the missing coefficient

3(2) + B(7) = -1

6 + 7B = -1

7B = -7

B = -1

A right triangle has side length 9,40, and 41 as shown below. Use these lengths t find cos Y, and tan Y, and sin Y.

Answers

Trigonometric functions are applicable to the right-angled triangles. The value of the Sin(Y), Cos(Y), and Tan(Y) are 0.976, 0.219 and 4.445.

What are Trigonometric functions?

$\rm Sin \theta=(Perpendicular)/(Hypotenuse)\n\n\nCos \theta=(Base)/(Hypotenuse)\n\n\nTan \theta=(Perpendicular)/(Base)$

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given to us

XY = 41

YZ = 9

XZ = 40

In ΔXYZ for ∠Y,

$\rm Sin \theta=(Perpendicular)/(Hypotenuse)\n\n\rm Sin (\angle Y)=(XZ)/(XY)\n\n\rm Sin (\angle Y)=(40)/(41)\n\n$

$\rm Cos \theta=(Base)/(Hypotenuse)\n\n Cos (\angle Y)=(ZY)/(XY)\n\n Cos (\angle Y)=(9)/(41)$

$\rm Tan \theta=(Perpendicular)/(Base)\n\nTan \theta=(XZ)/(ZY)\n\nTan \theta=(40)/(9)$

Hence, the value of the Sin(Y), Cos(Y), and Tan(Y) are 0.976, 0.219 and 4.445.

Final answer:

The cos Y, sin Y, and tan Y of a right triangle with side lengths of 9, 40, and 41 can be calculated using trigonometric ratios. Cos Y equals 9/41, sin Y equals 40/41, and tan Y equals 40/9.

Explanation:

In a right-angled triangle, we use the concept of trigonometric ratios which involves sine (sin), cosine (cos) and tangent (tan). Here, the side length 9 would be considered the adjacent side (a), the side length 40 would be considered the opposite side (b), and the side length 41 would be the hypotenuse (c).

The trigonometric ratios can be determined as follows:

Cosine (cos) Y = adjacent/hypotenuse = 9/41
Sine (sin) Y = opposite/hypotenuse = 40/41
Tangent (tan) Y = opposite/adjacent = 40/9

This would be the solution to finding the cos Y, tan Y, and sin Y with respect to angle Y.

How do you graph y=1x+3

Answers

Start on (0,3) since the y-intercept is 3. Move 1 unit up, 1 unit to the right. Then 1 unit down, one unit left....

When you are graphing, you need to remember that mx is the slope, and b is the y intercept. Since the y intercept is 3, you place your first point at (0,3). Now since the slop is positive one, you will go right 1, up one and place a point, and then right 1, up one and place a point and so on. You can also extend the line farther down by going left 1, down 1, etc.

During c basketball game, Deshown made 24 baskets out of 30 shots. Cody made 18 basketsout of 20 shots Who mode a greater percent of their shots?
What percent of his shots did DeShawn make?
?
% of his shots

Answers

Answer:

1. Cody made a greater percentage (i.e 90%) of his shots

2. Deshown made 80% of his shots

Step-by-step explanation:

To know who have a higher percentage, let us calculate their individual percentage. This is illustrated below:

For Deshown,

He made 24 baskets out of 30 shots.

The percentage of shot made = 24/30 x 100 = 80%

For Cody,

He made 18 baskets

out of 20 shots

The percentage of shot made = 18/20 x 100 = 90%

From the above calculations, Cody made greater percent of his shots

Answer:

1. Deshown made 80% of his shots

2. Cody made a greater 90% of his shots

3. Cody made a greater percent of his shots

What is the answer to 5/8 . 2/7 and what does the dot stand for the dot is actually a little higher

Answers

First, the dot stands for the "product". You have to multiply.

5/8* 2/7
= [5/ (2*4)]* (2/7)
= 5/4* 1/7 (because 2 and 2 cancel out)
= (5*1)/ (4*7)
= 5/28

The final answer is 5/28~

The dot stands for multiplication
