Answer:

Solution given:

AD=1.8

AC=3.0

we have

∆ADC is a right angled triangle

Cos A=b/h

<A=cos-¹ (1.8/3)

<A=53.13°

again

∆ABC is a right angled triangle

Tan A=p/b=BC/AC

Tan 53.13×3=BC

BC=4

NOW

Area of triangle =½(AC*BC)=½(4×3)=6 square units is a required area.

The graph of f(x)=3×2 -3 is shown below. g(x) is a transformation of f(x). How would you write the equation for the function g(x

umka2103 [35]

A function assigns the values. The function of the graph g(x) is 3(2ˣ).

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the function of the graph is f(x)=3(2ˣ)-3, which is needed to be transformed to g(x), since g(x) is the function of f(x) transformed 3 units upwards therefore, the function of g(x) can be written as,

g(x) = f(x) + 3

g(x) = 3(2ˣ)-3+3

g(x) = 3(2ˣ)

Hence, the function of the graph g(x) is 3(2ˣ).

A saleswoman earns 3% commission on all the merchandise that she sells. Last month she sold $3000 worth of merchandise. How much

Lynna [10]

She earned $90 commission last month.

Step-by-step explanation:

Given,

Commission rate of saleswoman = 3%

Sold worth of merchandise = $3000

Commission amount = 3% of sold worth

$Commission\ amount=\frac{3}{100}*3000\\\\Commission\ amount=\frac{9000}{100}\\\\Commission\ amount=\$90$

She earned $90 commission last month.

What is the difference between the number of solutions for a two-step equation and for a two-step inequality

Sophie [7]

Answer:

A two-step equation is something like:

A*X + B = C

In this case, like in a linear equation, we have only one solution that can be found as:

A*X = C - B

X = (C - B)/A

In the case of a two-step inequality, we have something like:

A*X + B > C

Solving this we get;

A*X > C - B

X > (C - B)/A

In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.

That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.
