dolphi86 [110]

The value of x is √8/3 - 2

Step by step explanation:

The given equation is

3(x+2)^2=8

To find x,

(x+2)²= 8/3

By taking square root on both sides

x+2= √8/3

x=√8/3 -2

x= -0.37

Thus the square root for the given value is -0.37

Which measurements could represent the side lengths of a right triangle?

AfilCa [17]

Answer:

16 cm, 30 cm, 34 cm

Step-by-step explanation:

I got this answer simply by plugging each number into my calculator with the following equation:

$\sqrt{x^{2} +y^{2} }$

When you the lower numbers into the equation, if the lengths really do give you a triangle, then you should get the largest number as your output. This can help you with any of the other questions that you may have to answer.

Xavier and Yolanda both have classes that end at noon and they agree to meet every day after class. They arrive at the coffee sh

Leto [7]

Answer:

$\mathbf{ \int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy }$

Step-by-step explanation:

Ask yourself, when will Xavier and Yolanda meet??

Firstly, since it is given that Xavier doesn't wait at all, in order for them to meet, Yolanda must arrive before Xavier. This in mathematical terms can be expressed as

$Y \leq X$

Secondly, Yolanda will wait for only 45 minutes, So Xavier must arrive before that, i.e

$X \leq Y+45$

Combining both conditions, we obtain

$Y \leq X \leq Y+45$

If $f(x)$ and $g(y)$ be the density functions for Xavier and Yolanda respectively, the probability of meeting is given by,

$\int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy$ .
