Answer:

Step-by-step explanation:

10x + 25y = 370

y = x + 5

10x+25(x+5)=370

10x+25x+125=370

35x=370-125

x=245/35

x=7 which is the number of dimes

x+7= 7+5= 12 which is the number of quarters

So you have 12 quarters. That means you have 7 dimes.

Help with cal 2 exercise involving integrals?

zhannawk [14.2K]

$\displaystyle\int\frac{\sqrt{x^2+1}}x\,\mathrm dx=\int\frac{\sqrt{\tan^2B+1}}{\tan B}\sec^2B\,\mathrm dB$

$\tan^2B+1=\sec^2B$

$\sqrt{\sec^2B}=\sec B$ (provided that $\sec B>0$ )

Then

$\dfrac{\sec B}{\tan B}\cdot\sec^2B=\dfrac{\sec^2B}{\tan B}\cdot\sec B$

(just moving around a factor of $\sec B$ )

$\dfrac{\sec B}{\tan B}\cdot\sec^2B=\dfrac{\sec^2B}{\tan^2B}\cdot\sec B\tan B$

(multiply by $\dfrac{\tan B}{\tan B}$ )

PLS i need help! and an explanation

serious [3.7K]

Answer:

C) 10.101

Step-by-step explanation:

A terminating decimal is one that is not repeating and ends at some point.

The line over the 3 in A means that it's a repeating decimal.

$\sqrt{10}$ is an irrational number, so it never ends.

The line over the 6 in D means that it's a repeating decimal.

C is the right answer because 10.101 has a definite endpoint :)

Alexxandr [17]

Answer:

length is 60 and width is 30

Step-by-step explanation:

because the formula to find perimeter is 2l+2w and if you plug 60 and 30 into that equation then you get 120+60 which is 180

Which graph represents the function h(x)=x+0.5

Fynjy0 [20]

Answer:

The correct graph of h(x) will be number 3 (c).

Step-by-step explanation:

We have the function h(x) = |x| + 0.5

On putting x=0, in the function h(x), we get,

h(0) = |0| + 0.5

h(0)=0 + 0.5

h(0)=0.5

Thus, the point (0,0.5) lie on the graph of h(x).
