Please help:<br> In Δ ABC, sin A=88, sin B=42, and a =17, find the length of b.

iren2701 [21]

Answer:

Step-by-step explanation:

Use the law of sines.

$\frac{sin A}{a} = \frac{sin B}{b} \\$

Plug values in.

$\frac{sin88}{17} = \frac{sin42}{b}\\$

Cross multiply.

$bsin88 = 17sin42\\b = 11.38$

Hope that helps.

Split up the interval [2, 5] into $n$ equally spaced subintervals, then consider the value of $f(x)$ at the right endpoint of each subinterval.

The length of the interval is $5-2=3$ , so the length of each subinterval would be $\dfrac3n$ . This means the first rectangle's height would be taken to be $x^2$ when $x=2+\dfrac3n$ , so that the height is $\left(2+\dfrac3n\right)^2$ , and its base would have length $\dfrac{3k}n$ . So the area under $x^2$ over the first subinterval is $\left(2+\dfrac3n\right)^2\dfrac3n$ .

Continuing in this fashion, the area under $x^2$ over the $k$ th subinterval is approximated by $\left(2+\dfrac{3k}n\right)^2\dfrac{3k}n$ , and so the Riemann approximation to the definite integral is

$\displaystyle\sum_{k=1}^n\left(2+\frac{3k}n\right)^2\frac{3k}n$

and its value is given exactly by taking $n\to\infty$ . So the answer is D (and the value of the integral is exactly 39).

Which of the following is the equation of a line perpendicular to the line Y=-1/3x+1, passing through the point (2,7)?

zimovet [89]

Y= 3X + 1. Perpendicular means you would change the slope by flipping it and changing the sign. So the slope then becomes 3. Then you use your points to find the y-intercept by filling in the variables. 7=3(2) + B. 7=6 + B. Then subtract 6 from both sides. B=1. Then you just put your problem back into slope intercept form with your new slope and y-intercept. Y=3x + 1.

Describe the steps you can use to find an average of fractional amounts

lutik1710 [3]

You do the same as whole numbers! Make sure the denominators are the same, add them all up, and then divide by the number of fractions there are!

Answer:

D. MN ⊥ LP

Step-by-step explanation:

Using HL for the proof requires that the triangles be right triangles. In order to ensure that is the case, you must have MN⊥LP.
