Answer:

Well, one way to use reasonableness is to estimate the answer to see if your answer is an outrageous answer or not. So, looking at your problem, you see that you are multiplying a two hundred something number by 4 and then subtracting 10 from it.

Find the slope of the line.

Luda [366]

(-2,5) (2,0)
Just use the slope formula to find slope.

m = (y2-y1)/(x2-x1)
m = (0-5)/(2+2)
m = -5/4

Hence, the slope of the line is -5/4.

Based on the diagram above, a student determined the hypotenuse of the triangle to be 6√3 Determine if the student's answer is c

zimovet [89]

Answer:

The student answer is wrong. The correct length of the hypotenuse is 12

Step-by-step explanation:

The question is incomplete without diagram. Find the diagram attached below.

The longest side of the right angled triangle is the hypotenuse.

The side facing the angle 30° is the opposite side of the triangle.

To find the hypotenuse, we will use the SOH CAH TOA method in trigonometry identity.

According to SOH:

Sin30° = Opposite/Hypoenuse

Sin30° = 6/Hypotenuse

Hypotenuse = 6/sin30°

Hypotenuse = 6/0.5

Hypotenuse = 6×2

Hypotenuse = 12

The student answer is wrong. The correct length of the hypotenuse is 12
