B, because you can't get the square root of a negative number

baherus [9]3 years ago

Answer:

Option B

Step-by-step explanation:

The given equation function is f(x) = $\sqrt{x-3}$

Domain of this function will be determined by (x-3) ≥ 0

because square root of negative numbers is not defined.

Option B is the answer.

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Ty

Westkost [7]

Answer:

The growth rate is 0.6

The growth factor is 1.6

Step-by-step explanation:

Generally, the exponential equation can be written as;

y = a(1 + r)^x

Where a is the initial value of 100

r is the growth rate

So let us form equations;

160 = 100(1 + r)^1 •••••(i)

Also;

256 = 100(1 + r)^2 •••••••(ii)

Divide equation ii by i

256/160 = 1 + r

1.6 = 1 + r

r = 1.6-1

r = 0.6

In the diagram the length of segment TR can be represented by 5x-4.

masya89 [10]

Answer: The correct option is D, i.e., 15 units.

Explanation:

It is given that the length of segment TR can be represented by 5x-4.

From figure it is noticed that the side TR and RV is equal and the length of segment RV is 2x+5. So,

$5x-4=2x+5$

$3x=9$

$x=3$

The value of x is 3, so the length of side RV is,

$2x+5=2(3)+5=11$

In triangle TRS and angle VRS,

TR=VR

$\angle TRS=\angle VRS=90^{\circ}$

RS=RS (common side)

By SAS rule of congruence triangle,

$\triangle TRS\cong\triangle VRS$

Therefore the side TS and VS are congruent sides.

From figure it is noticed that the length of side TS is 6x-3, therefore the length of side VS is also 6x-3.

$VS=6x-3=6(3)-3=15$

Hence, the length of side VS is 15 units and option D is correct.
