35) 60

36) 210

Step-by-step explanation:

34) Area of a rectangle:

L x B

= 15 x 5

= 75

35) Area of a trapezium :

½ h (sum of || sides)

= ½ x 6 x (12+8)

= 3 x 20

= 60

Answer:

Step-by-step explanation:

35. 75

area of rectangle : A = b x h

                                  = 15 X 5

                                   = 75

36. 60

area of trapezoid : A = <u>(b1 + b2) x h</u>

                                                2

                                  =<u> (8+12) x 6 </u>

                                            2

                                   = 60

37. 210

area of regular polygon : A = <u>P x a</u>  (P no. of sides) (a is apothem)

                                                   2

                                           = <u>(6 x 10) x 7</u>

                                                       2

                                           = 210

Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually consider
kiruha [24]

Answer:

Part A) V(t)=-5,750t+101,250

Part B) \$55,250

Step-by-step explanation:

Part A) Express the value of the bulldozer, V, as a function of how many years old it is, t.

Let

V ----> the value of the bulldozer (dependent variable or output value)

t ----> the number of years (independent variable or input value)

we know that

The linear function in slope intercept form is equal to

V(t)=mt+b

we have the ordered pairs

(0,101,250) and (15,15,000)

Find the slope

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

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{15,000-101,250}{15-0}

m=-\$5,750\ per\ year ----> is negative because is a decreasing function

The value of b is the initial value

so

b=\$101,250

substitute

V(t)=-5,750t+101,250

Part B) The value of the bulldozer after 8 years is

For t=8 years

substitute the value of t in the linear equation

V(t)=-5,750(8)+101,250=\$55,250

Find the measure of
sergij07 [2.7K]

Answer:

∠ ABC ≈ 137.9°

Step-by-step explanation:

Using the Cosine rule in Δ ABC

cos B = \frac{a^2+c^2-b^2}{2ac}

with a = 89, b = 144, c = 65

cos B = \frac{89^2+65^2-144^2}{2(89)(65)} = \frac{7921+4225-20736}{11570} = \frac{-8590}{11570} , thus

B = cos^{-1} ( - \frac{8590}{11570} ) ≈ 137.9° ( to the nearest tenth )

Find the value of k for x^2 - 2kx+7k -12=0 so that they have two equal roots
Alisiya [41]

Step-by-step explanation:

x^2 -2kx +7k -12 = 0

two equal roots -->Δ = b^2 -4ac = 4k^2 - 4(7k-12)=0 = 4(k^2 - 7k +12)=4(k-4)(k-3)=0

so k =3 and k =4
