Find the area of this shape.
aniked [119]

Answer:

Step-by-step explanation:

Bottom triangle

Area = b * height

b = 4 + 4 = 8 cm

h = 5.75

Area = 1/2 * 5.75 * 8

Area = 23 cm^2

Trapezoid

b1 = 8

b2 = 4

h = 2

Area = (b1 + b2)*h/ 2

Area = (8 + 4)*2 /2

Area = 12

Total area = 23 + 12

Total area = 35

Iam not sure about this questions answer can u give answer <br> Q10,11,12
irga5000 [103]

Answer:

10. First you multiply both sides by 3, making it 2x + 5 = 24

Then you subtract 5 from both sides making it 2x = 19

You dive both sides by 2 making x = 9.5

The answer is x = 9.5

11. First you need to find how much you need to pay each year. 12,000 x 0.05

you can make it easier by changing it to 120 x 5 = 600

You need to pay that for three years so 600 x 3 = 1800

Plus you need to pay the original money. 12,000 + 1,800 = 13,800      

The answer is $13,800    

12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000

Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4

The answer is 34.4 cm

Which sequence explains a geometric method of determining<br> 3 - 17i/2 +2i?
never [62]

Answer:

That would be D.

Step-by-step explanation:

first, turn both to polar form. Then you plot the first one and scale by the second. also, using a Rectangular to Polar calculator, we can see that 2.82 is 2 sqrt 2, so it cannot be A or B. It also can't be C since you graph 3-17i first.

Evaluate the difference quotient for the given function. Simplify your answer.
IgorC [24]

Answer:

-5 - h  

Step-by-step explanation:

ƒ(x) = 1 + 5x - x²

[f(5 + h) -f(5)]/h

= [1 + 5(5 + h) - (5 + h)² - 1 - 5(5) +5²]/h

= (25 + 5h - 25 - 10h - h² - 25 + 25)/h

= (-5h - h²)/h

= -5 - h

The difference quotient is -5 - h.
