Find mZXZx(5t - 13°Y(3t+ 3)
trapecia [35]

The diagram provided is an isosceles triangle. An isosceles triangle has two sides having equal measure and two base angles also having equal measure.

From the marks on the triangle given, line ZX and line ZY are equal in length. This also means angle X and angle Y are equal in measure.

Therefore, we would have;

\begin{gathered} 5t-13=3t+3 \\ \text{Collect all like terms and you'll have,} \\ 5t-3t=3+13 \\ 2t=16 \\ \text{Divide both sides by 2} \\ \frac{2t}{2}=\frac{16}{2} \\ t=8 \\ \text{If t=8, then} \\ 5t-13=5(8)-13 \\ 5t-13=40-13 \\ 5t-13=27 \end{gathered}

This means angle X and angle Y both equal 27 degrees each.

Note that the sum of angles in a triangle is 180. Therefore, in triangle ZXY,

What is the maximum number of snowmen they can make?
Anastasy [175]
To answer this question, you do 5 2/3 divided by 1/2. First, change 5 2/3 to 17/3. Then, use the reciprocal method by doing 17/3 times 2/1, which gives you 34/3. That’s 11.3 repeating, so they can make 11 whole snowmen.

Evaluate the upper and lower sums for f(x) = 1 + x2, −1 ≤ x ≤ 1, with n = 3 and 4.
Elenna [48]
I'm going to assume that your function is f(x) = 1 + x^2    (NOT x2).

I suspect you're trying to estimate the "area under the curve of f(x) = 1 + x^2.  You need to use this or a similar description to explain what you're doing.

Also, you need to specify whether you want "left end points" or "right end points" or "midpoints."  Again I must assume you want one or the other (and will assume that you meant "left end points").  

First, let's address the case n=3.  You must graph f(x) = 1 + x^2 between -1 and +1.     We will find the "lower sum," using "left end points."  The 3 x-values are {-1, -1/3, 1/3}.  Evaluate the function f(x) = 1 + x^2 at these 3 x-values.  Keep in mind that the interval width is 2/3.
The function (y) values are {0, 2/3, 4/3}.

Sorry, Michael, but I must stop here and await clarification from you regarding what you've been told to do in this problem.  Otherwise too much guessing (regarding what you meant) is necessary.  Please review the original problem and ensure that you have copied it exactly as presented, and also please verify whether this problem does indeed involve estimating areas under curves between starting and ending x-values.
