Determine the gcf. 2y^10, 5y^4, 6y^5

Sonja [21]

Answer:

y^4

Step-by-step explanation:

2y^10, 5y^4, 6y^5

We first need to find the factors of each term

2y^10 = 2*yyyyyyyyyy

5y^4 = 5yyyy

6y^5 = 3*2 yyyyy

The greatest common factor is the largest term that appears in all the terms

The greatest common factor is yyyy = y^4

Question 39/50

KatRina [158]

Using it's concept, it is found that there is a 0.64 = 64% probability that neither flight is delayed.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, there are 2 flights, each with a 0.8 probability of being on time. The flights are independent, hence the probability that both are on time is given by:

p = 0.8 x 0.8 = 0.64.

Jamie ran a total distance of 6 and 1 over 2 miles during the months of March and April. If Jamie only ran 1 over 6 mile every d

otez555 [7]

Given:

Total distance covered by Jamie = $6\dfrac{1}{2}$ miles

She ran every day = $\dfrac{1}{6}$ miles

To find:

The number of days in which she go for running.

Solution:

Total distance covered by Jamie $=6\dfrac{1}{2}$ miles

$=\dfrac{6\times 2+1}{2}$ miles

$=\dfrac{12+1}{2}$ miles

$=\dfrac{13}{2}$ miles

She ran every day = $\dfrac{1}{6}$ miles

Now,

$\text{Required number of days}=\dfrac{\text{Total distance covered}}{\text{Distance covered each day}}$

$\text{Required number of days}=\dfrac{\dfrac{13}{2}}{\dfrac{1}{6}}$

$\text{Required number of days}=\dfrac{13}{2}\times \dfrac{6}{1}$

$\text{Required number of days}=39$

Therefore, the required number of days is 39.

may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^

koban [17]

<u>Answer:</u>

$x=2\sqrt{2}$ , $x=-2\sqrt{2}$ , $x=4i$ , $x=-4i$

<u>Step-by-step explanation:</u>

$x^4+11x^2=3x^2+128$

First, we subtract 128 from both sides:

$x^4+11x^2-128=3x^2$

Then, we subtract $3x^2$ from both sides:

$x^4+8x^2-128=0$

Rewrite the equation:

$u^2+8u-128=0$

Insert and solve:

$u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i$
