Answer:

52

Step-by-step explanation:

the sequence is increasing by 4

hence, the nth term in n = 4(n) -16

hence, 17th term = 4(17) -16 = 52

What is the area of this triangle?<br><br> A=bh2
Galina-37 [17]
Alright, so you know that the formula for the area of a triangle is a=bh/2 

First start out by identifying your base and height. 

Base is the side that the shape is "standing on", in this case, that would be 9cm. 

Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm. 

Now, plug these values into your formula 

(12)(9) /2 = 54 cm squared! hope this helps :)

How long will it take a $800 investment to be worth $900 if it is continuously compounded at 11% per year?
Kruka [31]
The formula is
A=p e^rt
A future value 900
P present value 800
E constant
R interest rate 0.11
T time?

We need to solve for t
T=[log (A/p)÷log (e)]÷r
T=(log(900÷800)÷log(e))÷0.11
T=1.07 years round your answer to get 1 year

Decide !!!!!!!!!!!!!!!!!!
Savatey [412]

Make note of the coefficients in the first and fourth equations. They've been conveniently picked so that subtracting one equation from the other eliminates every variable but <em>t</em>. We have

(3<em>r</em> + 2<em>s</em> + <em>t</em> + 2<em>u</em> + 3<em>v</em>) - (3<em>r</em> + 2<em>s</em> + 3<em>t</em> + 2<em>u</em> + 3<em>v</em>) = 7 - 17

-2<em>t</em> = -10

<em>t</em> = 5

Please help, I’ve been stuck on this question for about a hour now.
Hoochie [10]
6x + 5x + (x + 16) + (3x - 1) = 360
11x + x + 16 + 3x - 1
15x + 15 = 360
15x = 345
x = 23


6(23) = 138
((23) + 16) = 39
(3(23) - 1) =68
5(23) = 115

138 + 39 + 68 + 115 = 360
