What is the point slope form of the line with slope 2/5 that passes through the point (−4, −7) ?

Sidana [21]

Answer:

The point slope form of that graph would be D) y + 7 = 2/5(x + 4)

Step-by-step explanation:

We know this by plugging into the point-slope form of the equation, which is listed below.

y - y1 = m(x - x1)

y - -7 = 2/5(x - -4)

y + 7 = 2/5(x + 4)

Answer:

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

Step-by-step explanation:

We need to write the expression that uses the associative property to make it easier to evaluate: $14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property of multiplication states that: $a(b\textbf{.}c)=(a\textbf{.}b)c$

So, For the given expression:

$14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

What is the volume of the composite figure? Express the

Papessa [141]

Answer:

$V=312\pi\ mm^{3}$

Step-by-step explanation:

we know that

The volume of the composite figure is equal to the volume of a semi-sphere plus the volume of the cone

$V=\frac{4}{6}\pi r^{3} +\frac{1}{3} \pi r^{2} h$

we have

$r=6\ mm$

$h=14\ mm$

substitute

$V=\frac{4}{6}\pi (6)^{3} +\frac{1}{3} \pi (6)^{2} (14)$

$V=144\pi +168\pi$

$V=312\pi\ mm^{3}$

Find the length of the curve on the given interval x=y^(1/2) from y=0 to y=4

Ulleksa [173]

Here we have to use the following formula

$l=\int\limits^a_b {\sqrt{1+(x')^2} \, dy$

x' is the derivative with respect to y

Given value of x is

$x = y^{1/2}$

Differentiating with respet to y

$x ' = \frac{1}{2y^{1/2}}$

Substituting the value of x' in the formula, we will get

$L=\int\limits^4_0 { \sqrt{1+\frac{1}{4y}}} \, dy$

$L = 4.65$
