Answer:

i solved for t and got

t= -3, -12

Step-by-step explanation:

Answer:

t = - 12, t = - 3

Step-by-step explanation:

Given

t² + 15t = - 36 ( add 36 to both sides )

t² + 15t + 36 = 0 ← in standard form

(t + 12)(t + 3) = 0 ← in factored form

Equate each factor to zero and solve for t

t + 12 = 0 ⇒ t = - 12

t + 3 = 0 ⇒ t = - 3

Answer:

2x

Step-by-step explanation:

i think this is correct, I'm not 100% sure that it is because the question was a little confusing.

ANSWER:

It would be 6x^3.

PRIOR NOTE:

For this question, it's slightly unclear regarding the formatting with it, but in here I'm going to assume that you've asked what is:

-2x * 3x * -x

when simplified. If it was something else, then the final answer would be different.

BACKGROUND:

To start, when multiplying two terms together, the variable will become squared or to the second power. For example:

2x * 2x = 4x^2

PROCESS:

With this question, it is asking for -2x * 3x * -x, though lets just start with the -2x * 3x part:

-2x * 3x = -6x^2

Now, finishing it off with the * -x part.

-6x^2 * -x = 6x^3

It goes to the third power, because now you have multiplied 3 x's together. The answer is also now positive since a negative * a negative = a positive.

With this, the final answer is 6x^3.

Answer:

12

Step-by-step explanation:

The average rate of change for f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 1, 3 ] , then

f(b) = f(3) = 27 ← value of y from table for x = 3

f(a) = f(1) = 3 ← value of y from table for x = 1

average rate of change = [tex]\frac{27-3}{3-1}[/tex] = [tex]\frac{24}{2}[/tex] = 12

The meter reading in ccf

The question is incomplete, as the  meter readings is not given. So, I will solve using an assumed value for the meter readings.

Let

[tex]x\ m^3 \to meter\ readings[/tex]

The readings in ccf is:

[tex]Reading = \frac{x}{2.832}[/tex]

Now, assume the value of x is 25; The readings will be:

[tex]Reading = \frac{25}{2.832}ccf[/tex]

[tex]Reading = 8.83\ ccf[/tex]

Answer:

ASA

Step-by-step explanation:

The ASA (angle side angle) identity states that if 2 triangles share 2 angles and one side in between the angles with each other, they are congruent. Since that is the case here, it is the answer.

Answer:

ASA

Step-by-step explanation:

When you have 2 angles and a side, look and see if the side is between the 2 angles.  What that means is that both angles share the one side.

If that happens, then the solution to congruence is ASA.  I'd be very careful about using SSA. There are exceptions and you should not choose it if you have a choice. Sometimes it works and sometimes it does not.

Answer:

y = 1/4x + 1/2 and x = -2 +4y

Step-by-step explanation:

Solving it in a way that x/4 is a fraction and not division so you would make that 1/4x. y = x/4 +1/2 x/4 is 1/4x so then you subtract 1/2 from both sides to get y - 1/2 = 1/4x. You can then divide 1/4 on both sides. -1/2 divided by 1/4 is -2 and 1/4y. This will get your answer of x = 1/4y -2 for x. Y is just 1/4x + 1/2

Answer:2.77*10^-8

Step-by-step explanation:

8.89*10^-7/32.0

The capacitance of the capacitor is approximately 2.78 x 10⁻⁹ Farads (F).

The capacitance of a capacitor can be calculated using the formula:

C = Q / V

Where C represents the capacitance, Q represents the charge stored in the capacitor, and V represents the voltage applied to the capacitor.

In this case, we are given that the charge stored in the capacitor is 8.89 x 10⁻⁷ C and the voltage applied is 32.0 V. Plugging these values into the formula, we get:

C = (8.89 x 10⁻⁷ C) / (32.0 V)

Simplifying the expression, we find:

C ≈ 2.78 x 10⁻⁹ F

The Farad is the SI unit of capacitance, representing the ability of a capacitor to store charge per unit voltage.

Answer:

[tex]\frac{11\sqrt{2}}{2}}[/tex] or 5.5√2

Step-by-step explanation:

We can see that this is a 45-45-90 triangle

refer to the image below to see what that means

we can see that (in the image) 11=x√2

which means that x= 11/√2

to rationalize this fraction we mulitply both sides by √2 to get

Answer:

[tex]d=10[/tex]

Step-by-step explanation:

Pythagorean theorem:

[tex]d^2+d^2=10\sqrt{2}^2,\\2d^2=200,\\d^2=100,\\d=\boxed{10}[/tex]

Alternative:

[tex]\cos 45^{\circ}=\frac{d}{10\sqrt{2}},\\\frac{\sqrt{2}}{2}=\frac{d}{10\sqrt{2}},\\2d=10\sqrt{2}\cdot \sqrt{2},\\2d=20,\\d=\boxed{10}[/tex]

Alternative (derived from the Pythagorean theorem):

All 45-45-90 triangles have side lengths [tex]x-x-x\sqrt{2}[/tex], where [tex]x\sqrt{2}[/tex] is the hypotenuse. Since this triangle's hypotenuse is [tex]10\sqrt{2}[/tex], its sides are [tex]10-10-10\sqrt{2}[/tex].

Answer:

y = 4/5x + 32/5

Step-by-step explanation:

(-3,4) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-4)/(2+3)

m= 4/5

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = 4/5(x + 3)

y - 4 = 4/5x + 12/5

y = 4/5x + 32/5

There are only two possible outcomes in the table that satisfy x ≤ -3; either x = -5 or x = -3. Then

Answer:

$4.5

Step-by-step explanation:

Let the amount of money

Maria had = x

Nick had = y

All together Maria and Nick had $12.

= x + y = 12

x = 12 - y

After Maria spent 30% of her money and Nick spent 50 % of his money, Maria and Nick were left with the same amount.

30% of x = 50% of y

30/100 × x = 50/100 × y

0.3x = 0.5y

We substitute 12 - y for x above

0.3(12 - y) = 0.5y

3.6 - 0.3y = 0.5y

3.6 = 0.5y + 0.3y

3.6 = 0.8y

y = 3.6/0.8

y = $4.5

Therefore, in the beginning, Nick originally had $4.5
