This is not a function. There are multiple outputs for the same input at $x=2$ . A function only has 1 output for every input.

Find the area under the curve y = 13/x3 from x = 1 to x = t. Evaluate the area under the curve for t = 10, t = 100, and t = 1000

zvonat [6]

Answer:

t = 10

$A = 32496.75$

t = 100

$A = 324999996.8$

t = 1000

$A=3.25\times 10^{12}$

Step-by-step explanation:

The area under the curve is calculated by using the following definite integral:

$A = \int\limits^t_ {1} \,{13\cdot x^{3}} dx$

$A = 13 \int\limits^t_1 {x^{3}} \, dx$

$A = \frac{13}{4}\cdot (t^{4}-1)$

Evaluated areas are presented below:

t = 10

$A = 32496.75$

t = 100

$A = 324999996.8$

t = 1000

$A=3.25\times 10^{12}$

HELP???

Bond [772]

25×(1−0.18)^(4)
=11.30

25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours

4x - y = 3<br> ax + 10y = 6<br> Solve for y

Mademuasel [1]

Answer:

Step-by-step explanation:

First Question: 4x-y=3

Second Question: ax+10y=6

First Answer: y=3-4x

Step 1: Property of Inequality!

4x-y=3 = (4x-4x) - y=(3-4x)

Step 2: Solve!

4x-4x=0 which leaves us with y=3-4x

Second Answer: y=6/10

Step 1: Property of Inequality!

ax+10y=6 = (ax-ax) + 10y= (6-ax)

Step 2: Solve!

10y=6 which leaves us with y=6/10
