X=112
Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!

A coordinate grid is placed over a college Station map. Tiger Stadium is located at (-3,2)
Olin [163]

Answer:

4.61\ units

Step-by-step explanation:

<em><u>The complete question is</u></em>

A coordinate grid is placed over a  College Station map.  Tiger Stadium is         located at (-3, 2) and Kyle Field is located at (4, 8).  If a shuttle bus stop is         at the midpoint between Tiger Field  and Kyle Field, which is the closest to         the distance in coordinate units from  Tiger Field to the shuttle bus stop?

<u><em>Options</em></u>

4.61 units

6.52 units  

9.22 units  

21.25 units

step 1

Find the midpoint between Tiger Field  and Kyle Field ( shuttle bus stop)

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have the points

(-3, 2) and (4, 8)

substitute in the formula

M=(\frac{-3+4}{2},\frac{2+8}{2})

M=(0.5,5)

step 2

Find the distance from  Tiger Field to the shuttle bus stop

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have the points

(-3,2) and (0.5,5)

substitute in the formula

d=\sqrt{(5-2)^{2}+(0.5+3)^{2}}

d=\sqrt{(3)^{2}+(3.5)^{2}}

d=\sqrt{21.25}\ units

d=4.61\ units

16) A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by E'(x) =
erastova [34]

Answer:

$61

Step-by-step explanation:

Given

Number of days, x = 5

Expenditure per day, E'(x) = 10x + 11

Required

Determine the expenditure per day (E'(x))

From the question, we have that

E'(x) = 10x + 11

Substitute 5 for x

E'(5) = 10 * 5 + 11

E'(5) = 50 + 11

E'(5) = 61

Hence, the expenditure for 5 days is $61
