Answer:

Step-by-step explanation:

Please use parentheses so that there's no question about what constitutes the argument of the sqrt function:

y=2 sqrt x+4 → y = 2√(x + 4)

This result is obtained from y = √x by:

1) translating the graph of y = √x 4 units to the LEFT, and

2) stretching the resulting graph vertically by a factor of 2.

Find the measure of the missing angles in the kite

ser-zykov [4K]

Answer:

x = y = 104°

Step-by-step explanation:

The sum of the interior angles = 360°

The opposite angles x and y are congruent , that is y = x , then

92 + 60 + x + x = 360

152 + 2x = 360 ( subtract 152 from both sides )

2x = 208 ( divide both sides by 2 )

x = 104

Then

x = y = 104°

Allan has a piece of string that is 5.4 meters in length. He needs some smaller pieces that are 0.6 meters in length. How many s

eduard

<h3>Option D</h3><h3>9 smaller pieces of string can be cut from Allan's string</h3>

<em><u>Solution:</u></em>

Given that,

Allan has a piece of string that is 5.4 meters in length

He needs some smaller pieces that are 0.6 meters in length

Therefore,

Total length of string = 5.4 meter

Length needed = 0.6 meter

Thus,

$\text{ Number of pieces } = \frac{ \text{ Total length of string }}{ \text{ Length needed }}\\\\\text{ Number of pieces } = \frac{5.4}{0.6}\\\\\text{ Number of pieces } = 9$

Thus, 9 smaller pieces of string can be cut from Allan's string

This question is confusing. Please help me!

fgiga [73]

Answer:

(A) y - x

Step-by-step explanation:

Finding a:

ax + x² = y² - ay
ax + ay = y² - x²
a(x+y)= (y+x)(y-x)
a = y - x

Correct choice is (A)

The curve with equation y=e^2x/4+3e^x has one stationary point.find the exact value of the coordinates of this point

Softa [21]

$y=\dfrac{e^{2x}}{4+3e^x}$
$\implies y'=\dfrac{2e^{2x}(4+3e^x)-3e^xe^{2x}}{(4+3e^x)^2}$
$\implies y'=\dfrac{8e^{2x}+3e^{3x}}{(4+3e^x)^2}$

Stationary points occur where the derivative is zero. The denominator is positive for all $x$ , so we only need to worry about the numerator.

$8e^{2x}+3e^{3x}=e^{2x}(8+3e^x)=0$

$e^{2x}>0$ for all $x$ , so we can divide through:

$8+3e^x=0\implies e^x=-\dfrac83$

But $e^x>0$ for all $x\in\mathbb R$ , so this function has no stationary points...

I suspect there may be a typo in the question.
