You can write every speed as the ratio between the space and time, so in this case you have

$\dfrac{12\text{ inches}}{3\text{ minutes}} = 4\ \dfrac{\text{inches}}{\text{minute}}$

What is the solution to this?

Ahat [919]

Answer:

$\frac{5}{4}$ $x^{4}$ + sinx + c

Step-by-step explanation:

using the power rule

∫(a $x^{n}$ ) = $\frac{a}{n+1}$ $x^{n+1}$ and ∫cosx = sinx

∫(5x³ + 2cosx )dx

= $\frac{5}{4}$ $x^{4}$ + 2sinx + c ( c is the constant of integration )

Multiply Conjugates Using the Product of Conjugates Pattern

SpyIntel [72]

Answer:

The product is the difference of squares is $\left(11-b\right)\left(11+b\right)=121-{{b}^2}$

Step-by-step explanation:

Explanation

The given expression is (11-b)(11+b).

We have to multiply the given expression.

Square the first term 11. Square the last term b.

$\begin{aligned}&(11-b)(11+b)=(11)^{2}-(b)^{2} \\&(11-b)(11+b)=121-b^{2}\end{aligned}$

An equiangular triangle has one side of length six inches. What is the height of the triangle, drawn from that side, to the near

tino4ka555 [31]

Answer:

The height of the triangle is 5.2 inches

Step-by-step explanation:

we know that

An <u>equiangular triangle</u> is a triangle where all three interior angles are equal in measure

Remember that an equilateral triangle has three equal sides and three equal interior angles

An equiangular triangle Is the same that an equilateral triangle. The measure of its interior angles is equal to 60 degrees

Let

h ----> the height of triangle

b ---> the length side of the triangle

Applying Pythagoras Theorem

$h^2=b^2-(b/2)^2$

we have

$b=6\ in$

substitute

$h^2=6^2-(6/2)^2$

$h^2=36-9$

$h^2=27$

$h=\sqrt{27}\ in$

$h=5.2\ in$

see the attached figure to better understand the problem
