Answer:

1st option: -2 < x ≤ 3

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that our x-values span from -2 to 3. Since -2 is an open dot, we cannot include it in our domain:

(-2, 3] or -2 < x ≤ 3

A construction company wants to build an auditorium on a trapezium shaped plot measuring 410m2. One of the parallel sides of the
Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

A=\frac{1}{2}\times h \times (x+y)

now, we can plug values

A=\frac{1}{2}\times 20 \times (x+18)

we can set A=410

and then we can solve for x

410=\frac{1}{2}\times 20 \times (x+18)

10\left(x+18\right)=410

x+18=41

x=23

H(t)=(t+3)^2+5
sineoko [7]

Answer:

Option C. −4≤t≤−3

Step-by-step explanation:

we have

H(t)=(t+3)^2+5

This is the equation of a vertical parabola written in vertex form

The parabola open upward (the leading coefficient is positive)

The vertex is a minimum

The vertex is the point (-3,5)

The function is increasing in the interval [-3,∞)

The function is decreasing in the interval (-∞,-3]

The function will have a negative average rate when the function will be decreasing

therefore

the answer is option C
