This is all the points i have left please help please with either

For question 26 the answer is ( 9^210 )

For question 27 the answer is ( 24 )

Step-by-step explanation:

For question number 26: try on the scientific calculator the equation you have pictured it will give you a very long number beginning with 《 2459953978》

Then put the the 9^210 on the calculator and click ( =) if it didn't work try clicking S》D then you will get the same long number Count at least the first 6 numbers for assurance

For question number 27 :The volume of a right cone is given by 

 Here, you only know the value of one of the variables, V, so you'll need to use the information in the question to somehow write r and h in terms

If the cone is three times as wide at the base as it is tall, then call the diameter 3x and the height of the cone one-third of that, or x. The volume formula calls for the radius, which is half the diameter, or 

Substitute these values into the formula and solve for x:

The question asks for the diameter of the base, which is 3x = 3(8) = 24.

did you get the answer yet?

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
