Answer:

Hey! Sorry im too late lol but here-

Step-by-step explanation:

Example of tangent in the real world-

When a stone gets tied at one end of a string & the other end is rotated, then the stone will form a circle.

How you know the tangent and radius are perpendicular:

The radius is formed vertically and is completely straight, while the tangent is completely straight but horizontal. You can draw a right triangle angle between the radius and tangent line by adding a third line, and a right angle is 90 degrees. So, this forms a perpendicular line.

Hope this helped :))

A student earned grades of Upper AA, Upper DD, Upper AA, Upper CC, and Upper BB. Those courses had the corresponding numbers

dmitriy555 [2]

Answer:

The grade point average is 2.92

The student didn't make the Dean's list because the student's GPA is less than 3.0

Step-by-step explanation:

I take the grades as A,D,A,C,B not AA,DD,AA,CC,BB.

I take numbers of credit hours as 4,2,2,3,1 not as 44, 22, 22, 33, and 11.

Since quality points to letter grades are A=4; B=3; C=2; D=1; F=0, weighted mean is the sum of the qulity points times corresponding credit hours divided by the total credit hours:

$\frac{(4*4) + (1*2) + (4*2) + (2*3) + (3*1)}{12}$ ≈ 2.92

Since 2.92<3.0, the student is not in Dean's list.

Malika charges $7.20 per hour for babysitting she babysits four hours each week she spends $10 per week and puts the rest of her

Liula [17]

$7.20 x 4 = $28.80
$28.80 - $10 = $18.80

12 x $18.80 = $225.60

1/4 of $225.60 = $56.40

$225.60 + $56.40 = $282

In total Malika has $282 in her savings account
