Step-by-step explanation:

By Geometric mean property:

${16}^{2} = x \times 3x \\ \\ \therefore \: 3 {x}^{2} = {16}^{2} \\ \\ \therefore \: {x}^{2} = \frac{{16}^{2} }{3} \\ \\ \therefore \: {x} = \sqrt{ \frac{{16}^{2} }{3} } \\ \\ \therefore \: {x} = { \frac{16}{ \sqrt{3} } } \\ \\ \therefore \: {x} = { \frac{16 \sqrt{3} }{ 3} } \\ \\ \therefore \: {x} = { \frac{16 \times 1.732}{ 3} } \\ \\ \therefore \: {x} = { \frac{27.712}{ 3} }\\ \\ \therefore \: {x} = 9.23733333 \\ \\ \huge \red{ \boxed{ \bold{\therefore \: {x} = 9.24}}}$

Answer:

As x decreases without bound, f(x) increases without bound

As x increases without bound, f(x) approaches 0

Step-by-step explanation:

As x gets more and more negative f(x) gets bigger and bigger

f(x) = (7/10) ^ x but x is negative so flip it and then x is a larger number

(10/7) ^ large number so it will get larger

as → -∞ f(x) →∞

As x gets more and more positive f(x) gets smaller and smaller

f(x) = (7/10) ^ x closer and closer to 0. The denominator gets larger faster than the numerator = 1 / large number

as → ∞ f(x) →0

If DE≅EF, CD = v + 45, and CF = 4v, what is the value of v?

irinina [24]

Answer:

<h2>since DE≅EF</h2>

CD=CF (cpct)

$v + 45 = 4v \\ 4v - v = 45 \\ 3v = 45 \\ v = \frac{45}{3} \\ v = 15$

Which fraction has the same value as 0.6

Zinaida [17]

Using the place value chart we can see that the decimal 0.6 is six tenths, so we can write 0.6 as the fraction $\frac{6}{10}$ . Notice however that $\frac{6}{10}$ is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 10 which is 2.

Answer:

Option B: 3x + 3y - 3

Step-by-step explanation:

In an isosceles triangle, the two congruent sides are equal.

We are told the base is; x - y - 2 units

Now let each of the congruent sides be represented as A.

Thus the perimeter equation will be;

P = 2A + x - y - 2

Now, we are told that the perimeter is; 7x + 5y - 8 units

Thus;

7x + 5y - 8 = 2A + x - y - 2

Rearranging gives;

7x - x + 5y + y - 8 + 2 = 2A

2A = 6x + 6y - 6

Divide through by 2 to give;

A = 3x + 3y - 3 units
