Answer:
32°
Step-by-step explanation:
The model forms a triangle. The sum of the angles of a triangle is 180°. Solve with the following equation:
? + 90 + 58 = 180
? + 148 = 180
? = 32
Therefore, the angle of elevation is 32°.
Answer:
y=x+2
Step-by-step explanation:
To find the equation of a line or linear function, you need at least two points that lie on the line. This is to find the slope or gradient of the line if it's not given. Let's use the two points (0,2) and (-2,0). The first coordinate in each point is X and the second is the y coordinate.
GRADIENT/SLOPE=[y1-y2]/[x1-x2]
=[2-0]/[0-2]=1
The equation of a linear function is given. by Y-y1=m(X-x1)
Y-2=1(X-0)
Y=X+2
VERIFICATION OF SOLUTION
You may want to verify whether you are right by substituting values of x to see if you can obtain corresponding y values.
Example: if x=0, y=0+2=2.This confirms first point
Answer:
2 1/3 - -3 1/4 = 2 1/3 + 3 1/4 = 5 7/12
-1.25*-3 1/4 = 4.0625
Step-by-step explanation:
The greatest difference will be two numbers which subtracted give the largest value.
2 1/3 - -3 1/4 = 2 1/3 + 3 1/4 = 5 7/12
This is the greatest value because it is the greatest number and the least number.
The greatest product will be -1.25 and -3 1/4 since both numbers are negative they give a positive solution.
-1.25*-3 1/4 = 4.0625
Answer:
Honor students have a probability of 43% to non-honor students 25%.
Step-by-step explanation:
Prob of honor student getting math class choice = 215/500 = 43%
Prob of non-honor student getting math class choice = 125/500 = 25%
