Answer:

16.7

Step-by-step explanation:

We can use the Pythagorean theorem, a^2 + b^2 = c^2.

a = 11

c = 20

11^2 + b^2 = 20^2

121 + b^2 = 400

b^2 = 279

b = sqrt(279) = 16.7

The current flowing through an electric circuit is the derivative of the charge as a function of time. If the charge q is given

blsea [12.9K]

Answer:

The current at t = 0 is

$I (0) = 2$ units of current

Step-by-step explanation:

If the current flowing through an electric circuit is defined as the derivative of the charge as a function of time and we have the equation of the charge as a function of time, then, to find the equation of the current, we derive the equation of the charge.

$q (t) = 3t ^ 2 + 2t-5$

$\frac{dq(t)}{dt} = 3 (2) t ^ {2-1} +2t ^ {1-1} -0$

Simplifying the expression we have:

$\frac{dq(t)}{dt} = 6t + 2t ^0\\\\\frac{dq(t)}{dt} = 6t + 2 = I (t)$

Finally, the equation that defines the current of this circuit as a function of time is:

$I (t) = 6t +2$

Now to find the current at t = 0 we make $I (t = 0)$

$I (0) = 6 * 0 +2$

$I (0) = 2$ units of current

Solve 4(2x - 1) - 3 = 9(x - 4). (1 point)

DiKsa [7]

Answer:

$x = 29$

Step-by-step explanation:

First we will expand the equation using the rule

$x(y - z) = xy - xz$

Thus,

$4(2x - 1) - 3 = 9(x - 4)$

is equal to

$8x - 4 - 3 = 9x - 36$

Simplify:

$8x - 7 = 9x - 36$

Add 36 to both sides:

$8x + 29 = 9x$

Therefore,

$x = 29$

Different cereals are randomly selected and the sugar content in grams of sugar per grams of cereal are obtained. Use a .05 sign

Elanso [62]

Answer:

Step-by-step explanation:

Hello!

X: content of sugar of a sample of cereal.

Data set:

0.03, 0.24, 0.30, 0.47, 0.43, 0.07, 0.47, 0.13, 0.44, 0.39, 0.48, 0.17, 0.13, 0.09, 0.45, 0.43

n= 16

$\frac{}{X}$ = 0.295g

S= 0.17g

You have to test if the mean sugar content is less than 0.3g

H₀: μ ≥ 0.3

H₁: μ < 0.3

α: 0.05

Assuming that the variable has a normal distribution, you have to conduct a t test:

$t= \frac{\frac{}{X}-Mu }{\frac{S}{\sqrt{n} } } ~~t_{n-1}$

$t_{H_0}= \frac{0.295-0.30}{\frac{0.17}{\sqrt{16} } } = -0.12$

p-value: 0.4533

The p-value is greater than α, the decision is to not reject the null hypothesis.

At a 5% significance level the decision is to not reject the null hypothesis. You can conclude that the average sugar content of the cereal is equal or greater than 0.3g of sugar per gram of cereal.

I hope this helps!
