Answer:

(2/3)(e^t +1)^(3/2)

Step-by-step explanation:

Use the substitution ...

u = e^t +1

Then du = e^t and you are finding the integral of ...

∫u^(1/2)·du

which you know by the power rule is ...

(2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)

Please help me out with this.......

Answer:

y = 0.5x + 5

Step-by-step explanation:

The equation is in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Given the ordered pair (0, 5 ) then c = 5

Calculate the multiplier using the slope formula

with (x₁, y₁ ( = (0, 5) and (x₂, y₂ ) = (2, 6) ← 2 ordered pairs from the table

m = $\frac{6-5}{2-0}$ = 0.5, hence

y = 0.5x + 5 ← equation relating x and y

Can someone please simplify the complex fraction?

dmitriy555 [2]

$\bf \cfrac{\qquad \frac{x+3}{4x^2-16}\qquad }{\frac{2x^2+10x+12}{2x-4}}\implies \cfrac{\frac{x+3}{4(x^2-4)}}{\frac{\underline{2}(x^2+5x+6)}{\underline{2}(x-2)}}\implies \cfrac{\frac{x+3}{4(x^2-2^2)}}{\frac{x^2+5x+6}{x-2}}\implies \cfrac{\frac{x+3}{4(x-2)(x+2)}}{\frac{(x+3)(x+2)}{x-2}}$

$\bf \cfrac{\underline{x+3}}{4\underline{(x-2)}(x+2)}\cdot \cfrac{\underline{x-2}}{\underline{(x+3)}(x+2)}\implies \cfrac{1}{4(x+2)}\cdot \cfrac{1}{x+2}
\\\\\\
\cfrac{1}{4(x+2)(x+2)}\implies \cfrac{1}{4(x^2+4x+4)}\implies \cfrac{1}{4x^2+16x+16}$
