Answer:

f(-4) = -18

Step-by-step explanation:

f(-4) means x = - 4

So Plug in x = - 4 into f(x) = 3x - 6

f(-4) = 3(-4) - 6

= -12 - 6

= -18

f(-4) = -18

DaniilM [7]

Answer: The required exponential model is $1804(1.04)^t$

Step-by-step explanation:

Since we have given that

Initial cases = 1804

Rate of growth = 4%

Since it is increasing exponentially,

So, it becomes,

$A=ab^t$

Here, a = 1804

b = $1+r=1+0.04=1.04$

So, it becomes,

$A=1804(1.04)^t$

Hence, the required exponential model is $1804(1.04)^t$

What is the area of this trapezoid?

liberstina [14]

Answer:

$7.5\:\text{square units}$

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

Height of 3
Bases of 1 and 4

The average of the bases 1 and 4 is equal to $\frac{4+1}{2}=\frac{5}{2}=2.5$

Therefore, the area of the trapezoid is $2.5\cdot 3=\boxed{7.5\:\text{square units}}$
