Wes bought a conference table for $960. what is it worth after depreciating at a rate of 12% per year for 4 years?
murzikaleks [220]

Answer:

$594.03

Step-by-step explanation:

Using the exponential function;

A = Pe^-rt

Principal = $960

Rate r = 12% = 0.12

Time t = 4years

Substitute

A = 960e^-(0.12*)*4

A = 960e^-0.48

A = 960(0.61878)

A = 594.03

HEnce the worth after 4years will be $594.03

Sean and his family are picking strawberries at a pick-your-own fruit farm. The rectangular strawberry field has an area of 210,
nasty-shy [4]

Answer:

512 ft is the length of the field

Step-by-step explanation:

Firstly, we need to know the area of the field. We have confirmed this to be rectangular. Since it’s a rectangular field, the area of the field can be obtained by multiplying the length of the field by the breadth or width of the field.

Mathematically A = L * W

In the question, A = 210,944 ft^2

L= ? and W = 412ft

In essence, we are trying to calculate the value for the length of the field

L = A/W

L = (210,944)/412 = 512ft

what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degr
MAVERICK [17]

Answer:

x ≈ 49.7°

Step-by-step explanation:

Since, the given triangle is an isosceles triangle,

Two sides having measure 17 units are equal.

Opposite angles of these equal sides will be equal.

Measure of the third angle = 180° - (x + x)°

By sine rule,

\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}

\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22} [Since, sin(180 - θ) = sinθ]

\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}

\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}

\frac{1}{17}=\frac{(\text{cos}x)}{11}

cos(x) = \frac{11}{17}

x = 49.68°

x ≈ 49.7°
