Answer:

cosine = adjacent / hypotenuse

cosine 62º = JL / 17

JL = cosine 62º * 17

JL = .47 * 17

JL = 7.99

JL = 8.0

In the expression 5n- 2m/7 + 3/4, what is the constant?<br> A. -2/7<br> B. 3/4<br> C. 5<br> D. 21

gavmur [86]

Answer:

Step-by-step explanation:

For this case we have the following expression:

5n-2m / 7 + 3/4

We have the following variables:

variable 1: n

variable 2: m

The terms that accompany the variables are coefficients

Therefore, the term that does not accompany the variables is the constant of the expression.

The constant is: 3/4

Answer:

the constant is 3/4

Evaluate the indefinite integral. (Use C for the constant of integration.)

IceJOKER [234]

$\displaystyle\int\frac{(\ln x)^{44}}x\,\mathrm dx$

$y=\ln x\implies\mathrm dy=\dfrac{\mathrm dx}x$

$\displaystyle\int y^{44}\,\mathrm dy=\frac{y^{45}}{45}+C$

$\displaystyle\int\frac{(\ln x)^{44}}x\,\mathrm dx=\frac{(\ln x)^{45}}{45}+C$

A cube has a height of 7 cm. What is the volume of the cube?

WITCHER [35]

Answer:

343

Step-by-step explanation:

if you have a cube, then the volume is one of the sides cubed, or to the third power. 7^3 can be represented as 7*7*7, or 7x7x7, which is 343.
