Answer:

D. 38.5 square units

Step-by-step explanation:

The area of an obtuse triangle can be figured out in the same way as any other triangle: ¹/₂bh. Substitute b and h for 11 and 7 respectively.

¹/₂(11(7))

1/2 * 77/1

77/2

The area of the triangle in this question is 38 1/2 (38.5) square units.

Answer:

Alternate Exterior Angles: {(1, 11), (4, 10), (5, 15), (8, 14)}Corresponding Angles: {(1, 9), (2, 10), (3, 11), (4, 12), (5, 13), (6, 14), (7, 15), (8, 16)}Alternate Interior Angles: {(2, 12), (3, 9), (6, 16), (7, 13)}Consecutive Exterior Angles: {(1, 10), (4, 11), (5, 14), (8, 15)}Consecutive Interior Angles: {(2, 9), (3, 12), (6, 13), (7, 16)}

Step-by-step explanation:

"Alternate" means the angles are on opposite sides of the transversal.

"Consecutive" means the angles are on the same side of the transversal. Sometimes, these are called "same-side" angles.

"Exterior" means the angles are outside the parallel lines.

"Interior" means the angles are between the parallel lines.

"Corresponding" means the angles are in the same direction from the point of intersection.

Alternate Exterior Angles: {(1, 11), (4, 10), (5, 15), (8, 14)}Corresponding Angles: {(1, 9), (2, 10), (3, 11), (4, 12), (5, 13), (6, 14), (7, 15), (8, 16)}Alternate Interior Angles: {(2, 12), (3, 9), (6, 16), (7, 13)}Consecutive Exterior Angles: {(1, 10), (4, 11), (5, 14), (8, 15)}Consecutive Interior Angles: {(2, 9), (3, 12), (6, 13), (7, 16)}

What is the equation of the line that passes through the point (-5, -3) and has a
slope of -1

Answers

Answer:

y= -x-8

Step-by-step explanation:

The ones in the equation are in subscript, couldn't get the equation creator to work properly....DO NOT multiply by one, they are merely subscript meant to help you identify which pair to use.

y-y1=m(x-x1)

-5=x1

-3=y1

-1=m

y- -3=-1(x- -5) then you arrive at y+3=-1(x+5)

y+3=-x-5 now you isolate the y on the left y=-x-8

Answers

Answer:

g=2

f=5

Step-by-step explanation:

add g to the other side on the 2nd equation. you should get f=7+gnow replace the f in the top equation with 7+g. the equation should now look like 7+g +3g = 15combine like terms to get 7+4g=15subtract 7 from both sides to get 4g=8divide by four to get g=2now plug 2 in for g in the 2nd equation to get f-2=7add 2 to both sides and get f=5

"Y varies directly as x". If y = 3 when x = 24, find y when x = 10.

Answers

Answer:

24=10

Step-by-step explanation:

The value of y when  x = 10 is 5/4

If y varies directly as x, this is expressed as:

[tex]y \alpha x\\y = kx\\[/tex]

where

k is the constant of proportionality

If y = 3 when x = 24, then:

3 = 24k

k = 3/24

k = 1/8

In order to get the value of x when y = 10

Recall that y = kx

y = 1/8 * 10

x = 10/8

y = 5/4

Hence the value of y when  x = 10 is 5/4

the polynomial function f(x) is graphed below. fill in the form below regarding the features of the graph​

Answers

Answer:

Part A

The degree of f(x) is 7

Part B

The leading coefficient negative

Part C

There are 5 distinct real zeros and 2 relative minimum values

Step-by-step explanation:

From the of a polynomial from a graph of the polynomial, starting from the left, we have;

1) The graph touches the x-axis (horizontally) and then crosses, which gives a multiplicity of 3

2) The graph crosses the x-axis once going upwards with a multiplicity of 1

3) Next, the graph crosses the x-axis once going downwards with a multiplicity of 1

4) Next, the graph crosses the x-axis once going upwards with a multiplicity of 1

5) Finally, the graph crosses the x-axis once going downwards with a multiplicity of 1

Part A

The degree of f(x) is therefore, 3 + 1 + 1 + 1 + 1 = 7

Part B

The leading coefficient of a polynomial that has an odd degree power with a graph falls to the right and rises to the left, the leading coefficient is negative;

Part C

The number of zeros = 7 zeros

The number of identical zeros = 3 identical zeros

∴ The number of distinct zeros are 7 zeros - 2 identical zeros = 5 distinct zeros

The graph continues from +∞ to -∞, therefore, the number relative minimum value of the polynomial are the two minimum values

The number of relative minimum values = 2

Therefore, there are 5 real distinct zeros and 2 relative minimum values
