Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

10n+0.3=0.1n+0.3

Step 1: Subtract 0.1n from both sides.

10n+0.3−0.1n=0.1n+0.3−0.1n

9.9n+0.3=0.3

Step 2: Subtract 0.3 from both sides.

9.9n+0.3−0.3=0.3−0.3

9.9n=0

Step 3: Divide both sides by 9.9.

9.9n/ 9.9 = 0/ 9.9

n=0

Answer:

Step-by-step explanation:

10n - .1n = 9.9n

9.9n + .3 = .3

subtract .3 from the other one and get 0

9.9n = 0 then divide and it comes out to 0

A guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°<br>

inysia [295]

Answer:

yes

Step-by-step explanation:

The tower is about 50.1 meters tall. The guidebook is correct.

The distance from the base of the tower to the angle vertex is ...

d1 = h/tan(46°)

d2 = d1 +50 = h/tan(27°)

Then the height of the tower is ...

h/tan(46°) +50 = h/tan(27°)

50 = h(cot(27°) - cot(46°))

h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692

h ≈ 50.1544 . . . meters

The tower is more than 50 meters high.

Hitman42 [59]

Answer:

Store Z

Step-by-step explanation:

Store X: 4 cans for $2.48, so 2.48/4= $0.62 per can

Store Y: 5 cans for $3.00, so 3.00/5= $0.60 per can

Store Z: $0.59 per can

Store Z offers the best deals since it cost less than the other

What is the maximum slope to f(x)= e^(-x^2)?

MA_775_DIABLO [31]

F'(x)=-2x{e^(-x²)}
Equating f'(x)=0,
i.e,

-2x{e^(-x²)}=0....eqn(i)
For maximum slope:
Differentiating (i) wrt x,we get,
4x² {e^(-x²)}-2 {e^(-x²)}=0
{e^(-x²)} [4x²-2]=0
4x²-2=0
x=1/√2

If f(x)=y then f'(x)=dy/dx=slope
So,
Maximum slope
= f'(x)
= -2x{e^(-x²)}
=-2×(1/✓2){e^(-1/✓2)²}
= -✓2{e^(-1/2)}
=(-sqrt 2/sqrt e)
=-sqrt(2/e)➡c is correct

A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a si

RSB [31]

Answer:

The height of the second prism is 12 units.

Step-by-step explanation:

First, we must know that the volume of a rectangular prism is equal to length x width x height. With this information, we can multiply the given dimensions of the first rectangular prism to get a volume of 2700 cubic units. From here, we must understand wha we need from the second rectangular prism. Because it has a square base of 15, that accounts for both its width and length. Therefore, we have that

$Volume= 15^2 x\\2700/225=x\\12=x$
