pls help me solve the missing answers thanks!

Answer:

Let's solve your system by elimination.

2a + 3c =66 ; 3a + 5c = 105

Multiply the first equation by 5,and multiply the second equation by -3.

5 (2a + 3c = 66)

−3 (3a + 5c = 105)

Becomes:

10a + 15c = 330

−9a − 15c = −315

Add these equations to eliminate c:

a = 15

Now that we've found a let's plug it back in to solve for c.

Write down an original equation:

2a + 3c = 66

Substitute 15 for a in 2a + 3c = 66:

(2)(15) + 3c = 66

3c + 30 = 66 (Simplify both sides of the equation)

3c + 30 −30 = 66 −30 (Add -30 to both sides)

3c = 36

3c3= 363 (Divide both sides by 3)

c = 12

Answer:

a = 15 and c = 12

Let's evaluate the expression,

→ (25^-3/2)^1/3

→ 25^-3/2×1/3

→ 25^-3/6

→ 5^-1/2×2

→ 5^-1 {or} 1/5

Hence, the answer is 1/5.

The function h(x) has a horizontal asymptote at y=5 and the  vertical asymptote is x=-2.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, h(x)=g(x+5.

Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k.

Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k.

Here, the horizontal asymptote is 3, and the vertical asymptote is -2

The graph of h(x) = g(x+5) had a horizontal asymptote at y=5 and the same vertical asymptote as function g(x).

Therefore, the function h(x) has a horizontal asymptote at y=5 and the  vertical asymptote is x=-2.

Answer:

it's 10.00 because I used a calculator

Length of side YZ to the nearest tenth is 16 ft

To solve this question we would use the sine rule. The sine rule states that

A/sin a = B/sin b

if we take our angle a to be XZY, and b to be ZXY.

Going by angles in a triangle, ZXY = 180 - 90 - 35 = 55. This means that our angle b is 55º

applying the sine rule, we have

11/sin 35 = B/sin 55

11/0.5736 = B/0.8192, if we cross multiply, we have

B = (11 * 0.8192)/0.5736

B = 9.0112/0.5736

B = 15.7 ft

Using implicit differentiation, it is found that the water level is rising a rate of 0.001 ft/sec.

The volume of a pool of length l, width w and height h is given by:

[tex]V = lwh[/tex]

Applying implicit differentiation, the rate of change of the volume is given by:

[tex]\frac{dV}{dt} = wh\frac{dl}{dt} + lh\frac{dw}{dt} + lw\frac{dh}{dt}[/tex]

Neither the width nor the length changes, hence [tex]\frac{dl}{dt} = \frac{dw}{dt} = 0[/tex], and:

[tex]\frac{dV}{dt} = lw\frac{dh}{dt}[/tex]

We are given that:

[tex]\frac{dV}{dt} = 0.3, l = 20, w = 40[/tex], hence:

[tex]\frac{dV}{dt} = lw\frac{dh}{dt}[/tex]

[tex]0.8 = 20(40)\frac{dh}{dt}[/tex]

[tex]\frac{dh}{dt} = \frac{0.8}{800}[/tex]

[tex]\frac{dh}{dt} = 0.001 [/tex]

The correct word form of 8.16 is b. eight and sixteen hundredths

Since the number is 8.16, we have 8.16 = 8 + 0.16 = 8 + 16/100

Since we have 8 in the units place, it is pronounced eight.

Also, we have our decimal part 0.16 = 16/100 which is pronounced as sixteen hundredths.

So, combining both we have eight and sixteen hundredths.

So, the correct word form of 8.16 is b. eight and sixteen hundredths
