I DONT UNDERSTAND HELP

Mathematics
1 answer:
Taya2010 [7]3 years ago
8 0

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><u>since </u><u>DE≅EF</u></h2>

<u>CD=</u><u>CF </u><u>(</u><u>cpct)</u>

<u>v + 45 = 4v \\ 4v - v = 45 \\ 3v = 45 \\ v =  \frac{45}{3}  \\  v = 15</u>

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
