Hey there!

First, if we count the number of points we have, we have eight. This means that it is an octagon.

I hope this helps!

A curve has equation y=x√x.find the equation of the tangent to the curve at the point(1, 5)

rewona [7]

Answer:

y - 5 = $\frac{3}{2}$ (x - 1)

Step-by-step explanation:

Note that $\frac{dy}{dx}$ = $m_{tangent}$

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x $\sqrt{x}$ = x. $x^{\frac{1}{2} }$ = $x^{\frac{3}{2} }$ , then

$\frac{dy}{dx}$ = $\frac{3}{2}$ $x^{\frac{1}{2} }$

When x = 1

$\frac{dy}{dx}$ = $\frac{3}{2}$ . 1 = $\frac{3}{2}$

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = $\frac{3}{2}$ and (a, b) = (1, 5), thus

y - 5 = $\frac{3}{2}$ (x - 1) ← equation of tangent

Solve for v. -8(v+7)=3v-23 Simplify your answer as much as possible. v=

aksik [14]

Answer:

v = -3

Step-by-step explanation:

-8(v + 7) = 3v - 23

Expand.

-8v - 56 = 3v - 23

Add -3v and 56 on both sides.

-8v - 56 + 56 - 3v = 3v - 23 + 56 - 3v

-8v - 3v = -23 + 56

Combine like terms.

-11v = 33

Divide -11 into both sides.

-11v/-11 = 33/-11

v = -3

Write an equation in slope intercept form thag passes through (4,-4) and is parallel to 3+4x=2y-9

uysha [10]

The original line is

4x - 2y = -12

The parallel lines will all be

4x - 2y = constant

and the constant is given by the point directly:

4x - 2y = 4(4) - 2(-4) = 24

2y = 4x - 24

y = 2x - 12

Answer: y = 2x - 12

Given:

$\begin{gathered} W(d)=1650(.85)^d \\ where,\text{ d is the number of days} \end{gathered}$

Requirement:

The percentage of the population of the weed increases each day.

Explanation:

let 1650.85 = P

So the percentage increases each day =

$\frac{P^d-P^{d-1}}{P^{d-1}}*\text{ 100}$ $=\text{ \lparen P}^1^{\text{ }}-\text{ 1\rparen *100}$

B

$(1650.85^1-1)*100$

By putting the value of P

Percentage = 164985%

Final Answer:

164985%
