Help, I’m stuck. Lol.
Darya [45]

Answer:

a. height = 12

b. area = 228

Step-by-step explanation:

a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that a^2+b^2=c^2, where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into c^2-b^2=a^2. 15^2=225, 9^2=81, and 225-81=\sqrt{144}=12. Therefore, the height of the parallelogram is \boxed{12}

b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and 19\cdot12=\boxed{228}

Limit question: lim x-->pi ((e^sinx)-1)/(x-pi)
aleksandr82 [10.1K]
\displaystyle\lim_{x\to\pi}\dfrac{e^{\sin x}-1}{x-\pi}

Notice that if f(x)=e^{\sin x}, then f(\pi)=e^{\sin\pi}=e^0=1. Recall the definition of the derivative of a function f(x) at a point x=c:

f'(c):=\displaystyle\lim_{x\to c}\frac{f(x)-f(c)}{x-c}

So the value of this limit is exactly the value of the derivative of f(x)=e^{\sin x} at x=\pi.

You have

f'(x)=\cos x\,e^{\sin x}\implies f'(\pi)=\cos\pi\,e^{\sin\pi}=-1

You invest an initial $2,000 in an account that has an annual interest rate of 6%, compounded daily. How much money will you hav
AleksAgata [21]
The total amount of money earned after 15 years is given by the formula:
A=p(1+r/100)^n
where:
p=principle=$2000
r=rate=6%
n=time=15 years
thus;
A=2000(1+6/100)^15
A=2000(1.06)^15
A=$4,793.12
