Answer:

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo  one is just a bigger copy of the other....

Step-by-step explanation:

Since this is a relation of the two side of each.. we can say the following...

\frac{6}{9} = \frac{4}{x}     where X = side  LA    soooo       solve for X  

 x *  \frac{6}{9} = 4   (move the X , to the other side of the '=' sign

x = 4 * \frac{9}{6}   ( yes.. we want to invert the fraction to move it to the other side )

x = \frac{36}{6}

x = 6

so side LA is 6    :)

Write two different equations that are perpendicular to <br> y=-1/4x - 1.
Monica [59]

Answer:

Step-by-step explanation:

perpendicular is 90 degrees or inverse slope of that point

y = -1/4x -1

so the inverse slope of -1/4 is 4

now the other equation is

y = 4x - 1

So the two equations are

y = -1/4x -1

y = 4x - 1

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3? x = –2 – StartRoot StartFraction 11 Over 2 EndFraction EndRoot
Phantasy [73]

Answer:

The zeros are

x=-2+\frac{\sqrt{22}}{2}

x=-2-\frac{\sqrt{22}}{2}  

Step-by-step explanation:

we have

f(x)=2x^{2}+8x-3

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

Equate the function to zero

2x^{2} +8x-3=0  

so

a=2\\b=8\\c=-3

substitute in the formula      

x=\frac{-8\pm\sqrt{8^{2}-4(2)(-3)}} {2(2)}  

x=\frac{-8\pm\sqrt{88}} {4} 

x=\frac{-8\pm2\sqrt{22}} {4} 

x=-2\pm\frac{\sqrt{22}}{2}

therefore

x=-2+\frac{\sqrt{22}}{2}

x=-2-\frac{\sqrt{22}}{2}

When peanuts are packaged in their shells, most shells have two peanuts inside, but some have three and some only have one. A qu
Oduvanchick [21]

Answer:

H0: p = 0.1 and Ha: p > 0.1

Step-by-step explanation:

At the null hypothesis, we test if the mean or proportion is equal to a certain value.

At the alternate hypothesis, we test if the mean or proportion is less than, more than, or different of the value tested at the null hypothesis.

A quality control inspector wants to determine if more than 10% of all shells contain just one peanut.

The value of 10% = 0.1 is tested, which means that the null hypothesis is H_{0}: p = 0.1

Test if it is more than 10% = 0.1, so the alternate hypothesis is: H_{a}: p > 0.1
