Rewrite 5/ 16 + 6/ 20 with a common denominator.

Troyanec [42]

25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.

Find the area under the curve y = 27/x3 from x = 1 to x = t. Evaluate the area under this curve for t = 10, t = 100, and t = 100

Darina [25.2K]

Answer:

Step-by-step explanation:

given is a function as

$y=\frac{27}{x^3}$

We are to find the area form x=1 to x=t

The curve from x=1 lies in the I quadratnt.

So area above x axis is to be calculated

Area = $\int\limits^t_1 {\frac{27}{x^3} } \, dx \\=\frac{-27}{2x^2} \\= \frac{-27}{2t^2}-\frac{-27}{2}\\=\frac{27}{2}(1-\frac{1}{t^2} )$

a) When t =10,

area = $\frac{27}{2} (1-\frac{1}{10^2} )\\= 13.365$

b) t=100

area = $\frac{27}{2} (1-\frac{1}{100^2} )\\= 13.49865$

c) t=10000

area = $\frac{27}{2} (1-\frac{1}{10000^2} )\\= 13.5$

PLS HELP ME ASAP FOR ALL 6!! (MUST SHOW WORK!!!) +LOTS LOTS OF POINTS!!!

Sedaia [141]

1. -4a-6=-12
add 6 to both sides
-4a-6+6=-12+6
-4a=-6
Divide by -4
$a= \frac{6}{4} = 1 \frac{1}{2}$

2. $\frac{3}{5} z- \frac{1}{4} = \frac{17}{20}$
add $\frac{1}{4}$ to both sides but you will need to make a common denominator on the right
$\frac{3}{5} z- \frac{1}{4} + \frac{1}{4} = \frac{17}{20} + \frac{5}{20}$
$\frac{3}{5}z= \frac{11}{10}$
Divide by $\frac{3}{5}$ which means multiply by the <span>reciprocal</span>.
$\frac{3}{5}* \frac{5}{3} z= \frac{11}{10} * \frac{5}{3}$
$z= \frac{55}{30} =1 \frac{5}{6}$

3. $2 \frac{1}{2}(e-1 \frac{3}{4})=5 \frac{1}{2}$
Distribute
$2 \frac{1}{2} e-4 \frac{3}{8} =5 \frac{1}{2}$
Subtract
$2 \frac{1}{2} e=1 \frac{1}{8}$
Divide
$e= \frac{9}{20}$

4. 3w+7=20
Subtract
3w=13
Divide
$w= \frac{13}{3} = 4 \frac{1}{3}$

5. -.2p+.4=-1.2
Subtract
-.2p=-1.6
Divide
p=8

6. $\frac{y}{4} - \frac{3}{5} = \frac{18}{20}$
Add, made sure you change to common denominator first
$\frac{y}{4} = 1 \frac{1}{4}$
Multiply by 4
y=5

Hope that helps

Write x = 1/4 y + 2 in slope intercept form.

kondor19780726 [428]

Answer:

y = 4x - 8

Step-by-step explanation:

x = 1/4y + 2

-1/4y -1/4y

-1/4y + x = 2

-x -x

-1/4y= -x + 2

*-4 *-4

y = 4x - 8
