Answer:

B: 6.0

Step-by-step explanation:

-3t^2+9t+54 = 0

This is the equation that needs to be solved

Divide both sides by -3

t^2 - 3t - 18 = 0

The factors of 18 are: (1 18) (2 9) (3 6)

3 - 6 = -3 and 3 x -6 = -18

So: (t + 3) (t - 6) = 0

t = -3, 6

It can't be negative so the answer is 6

A series circuit contains a resistor and an inductor as shown in the figure. Determine a differential equation for the current i

alukav5142 [94]

From the information given, the differential equation will be di/dt = (E - Ri) / L.

<h3>How to calculate the differential equation</h3>

From the information given, we can set up the differential equation as:

-E(t) = Ldi(t)/Dr + Ti(t) = 0.

Here, i(t) = I

E(t) = E

Therefore, this will be:

= -E + Ldi/dt + Ri = 0

We'll now solve for di/dt

Ldi/dt = E - Ri

di/dt = (E - Ri) / L

Luisa earns money mowing her neighbors' lawns.

Irina-Kira [14]

Answer:

$p(x)=16x-25$

C is the correct option.

Step-by-step explanation:

We have been given that

$r(x)=20x\\c(x)=4x+25$

The profit is the difference of revenue and cost function.

Mathematically, we can write profit function as

$p(x)=(r-c)x$

We know that $(f-g)(x)=f(x)-g(x)$ . Thus, we have

$p(x)=r(x)-c(x)$

Plugging, the r(x) and c(x) functions

$p(x)=20x-(4x+25)$

Distribute negative over the parenthesis

$p(x)=20x-4x-25$

Combine the like terms. 20x-4x = 16x

$p(x)=16x-25$

C is the correct option.

Rudik [331]

Answer:

$\$9,207$

Step-by-step explanation:

step 1

Find the lateral area

we know that

The lateral surface of a square pyramid is equal to the area of its four lateral triangular faces

$LA=4[\frac{1}{2}bh]$

where

$b=25\ m$

$h=18\ m$ ----> slant height

substitute the values

$LA=4[\frac{1}{2}(25)(18)]=900\ m^{2}$

step 2

Find the cost

$900(10.23)=\$9,207$
