Harry gave away 3/6, or half of the brownies

1/6 plus 2/6 equals 3/6

Harry gave away 3/6 or 1/3 fractions of the pan to his mom and his brother.

Harry baked a pan of brownies for his brother=1/6

Harry baked a pan of brownies for his mom=2/6

Total pan of brownies harry gave = 1/6+2/6

                                                          3/6=1/3

Answer:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

Step-by-step explanation:

To simplify this expression you must use the following trigonometric identities

[tex]cos(\frac{\pi}{2}-x) = sinx[/tex]     I

[tex]1-sin (x) ^ 2 = cos ^ 2(x)[/tex]      II

Remember that

[tex]\sqrt{f(x)^2} =f(x)[/tex]

Only if [tex]f(x)> 0[/tex]  for all x

If f(x) is not greater than 0 for all x then

[tex]\sqrt{f(x)^2} =|f(x)|[/tex]

Now we have the expression:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}[/tex]

then using the trigonometric identities I and II we have to:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{\sqrt{1-sin^2(x)}}\\\\\\\frac{sin^2(x)}{\sqrt{1-sin^2(x)}}= \frac{sin^2(x)}{\sqrt{cos^2(x)}}[/tex]

[tex]cos(x)[/tex] is not greater or equal than 0 for all x. So.

[tex]\frac{sin^2(x)}{\sqrt{cos^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

Finally  

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

The answer is:

The domain of the function is all the real numbers except the number 13:

Domain: (-∞,13)∪(13,∞)

This is a composite function problem. To solve it, we need to remember how to composite a function. Composing a function consists of evaluating a function into another function.

Composite function is equal to:

[tex]f(g(x))=(f\circ} g)(x)[/tex]

So, the given functions are:

[tex]f(x)=x+7\\\\g(x)=\frac{1}{x-13}[/tex]

Then, composing the functions, we have:

[tex]f(g(x))=\frac{1}{x-13}+7\\[/tex]

Therefore, we must remember that the domain are all those possible inputs where the function can exists, most of the functions can exists along the real numbers with no rectrictions, however, for this case, there is a restriction that must be applied to the resultant composite function.

If we evaluate "x" equal to 13, the denominator will tend to 0, and create an indetermination since there is no result in the real numbers for a real number divided by 0.

So, the domain of the function is all the real numbers except the number 13:

Final answer:

The car's average speed over the course of 5 days for a distance of 2359 miles was approximately 19.66 mph, which rounds to 20 mph.

Explanation:

To calculate the car's average speed in miles per hour, you divide the total distance traveled by the total time taken. In this case, the car traveled 2359 miles over the course of 5 days. Since there are 24 hours in a day, the total time in hours is 5 days multiplied by 24 hours per day.

Total time in hours = 5 days × 24 hours/day = 120 hours

Now we calculate the average speed using the formula:

Average speed = Total distance / Total time

Average speed = 2359 miles / 120 hours

When calculated, the average speed is approximately 19.66 miles per hour. Rounding to the nearest mile per hour gives us an average speed of 20 mph.

Answer:

a = 1, b = 7

Step-by-step explanation:

Given the 2 equations

3a + 6b = 45 → (1)

2a - 2b = - 12 → (2)

Multiply (2) by 3 and add to (1) to eliminate the term in b

6a - 6b = - 36 → (3)

Add (1) and (3) term by term

(3a + 6a) + (6b - 6b) = (45 - 36)

9a = 9 ( divide both sides by 9 )

a = 1

Substitute a = 1 in either (1) or (2) and solve for b

(1) → 3 + 6b = 45 ( subtract 3 from both sides )

6b = 42 ( divide both sides by 6 )

b = 7

Answer:

• cos(α/2) = (4/17)√17

• sin(α/2) = (√17)/17

Step-by-step explanation:

The appropriate hαlf-angle identities are:

sin(α/2) = √((1 -cos(α))/2)

cos(α/2) = √((1 +cos(α))/2)

Putting in your given values for cos(α), we have ...

cos(α/2) = √((1 +15/17)/2) = √(16/17) = 4(√17)/17

sin(α/2) = √((1 -15/17)/2) = √(1/17) = (√17)/17

Answer:

k = 13

smallest zero = -6

Step-by-step explanation:

f(x) is basically the function of x.

x could be any integer. f(x) is the solution of the function of x.

f(x) is defined as x² + 3x - 10

f(x) = x² + 3x - 10

Now, f(x+5) = x² + kx + 30

This statement here says that if the value of x is x+5, then the answer would be x² + kx + 30.

f(x) = x² + 3x - 10

f(x+5) = (x+5)² + 3(x+5) - 10

f(x+5) = x² + 10x + 25 + 3x + 15 - 10

f(x+5) = x² + 13x + 40 - 10

f(x+5) = x² + 13x + 30

x² + 13x + 30 = x² + kx + 30

hence, k = 13

Smallest zero = The smallest x value.

f(x+5) = x² + 13x + 30

Let's take f(x+5) = 0

x² + 13x + 30 = 0

which two numbers products give us 30 and add up to 13?

== 6 and 5

(x+6)(x+5) = 0

x+6 = 0

x = -6

x+5 = 0

Note:  Please use " ^ " to indicate exponentiation:

-2x^4 - x^3 + 8x^2 - 12

The equation -2x^4 - x^3 + 8x^2 = 12 is a 4th degree polynomial because the highest power of the variable is 4.

The equation given is a polynomial equation, and polynomials are classified by degree, which is the highest power of the variable. In the given equation -2x4 - x3 + 8x2 = 12, we can see that the highest power is 4, which is the degree of the x variable. Thus, this equation is a 4th degree polynomial equation.

The variable with the highest degree is used to classify the polynomial. In this case, the variable x has the highest degree, making it a 4th degree polynomial. The value of the degree helps us to understand the shape of the graph of the equation. In this case, a 4th degree polynomial could have 0, 2, or 4 real roots and the graph can have 2 turning points.

She spent 42.15 on dinner and brought home more than 20.00.

So, the inequality will be :

[tex]0.5x-42.15>20[/tex]

Step-by-step explanation:

4x + 8 = 88

4x +8 - 8 = 88 - 8

4x = 80

4x/4 = 80/4

X = 20

For this case we must find the value of "x" of the following linear equation:

[tex]4x + 8 = 88[/tex]

We subtract 8 on both sides of the equation:

[tex]4x = 88-8\\4x = 80[/tex]

We divide between 4 on both sides of the equation:

[tex]\frac {4x} {4} = \frac {80} {4}\\x = 20[/tex]

So, the value of x is 20

Answer:

The rock will take about 4.5 seconds to reach the river

Step-by-step explanation:

* lets study the situation of the rock

- The rock is dropped means the initial velocity is zero

- The motion is free fall under earth gravity

- The rock dropped from a bridge 320 feet above the river

- The equation of the pathway is h = -16t² + 320

- When the rock reach to the ground the height will be zero

* Now lets substitute h by zero in the equation to find t

∵ h = -16t² + 320

∵ h = 0

∴ 0 = -16t² + 320 ⇒ add 16t² to both sides

∴ 16t² = 320 ⇒ divide both sides by 16

∴ t² = 320/16 = 20

∴ t² = 20 ⇒ take √ for both sides

∴ t = √20 = 2√5 ≅ 4.5 seconds

* The rock will take about 4.5 seconds to reach the river

The final answer is D: 4.5 seconds.

let's go through the solution in more detail.

Given the equation [tex]\( h = -16t^2 + 320 \)[/tex], where [tex]\( h \)[/tex] represents the height of the rock above the river at time [tex]\( t \),[/tex] we're trying to find out when the rock reaches the river, which means its height will be 0.

So, we set [tex]\( h \)[/tex] to 0:

[tex]\[ 0 = -16t^2 + 320 \][/tex]

To solve for [tex]\( t \),[/tex] we isolate [tex]\( t \)[/tex] by moving [tex]\( -16t^2 \)[/tex] to the other side of the equation:

[tex]\[ 16t^2 = 320 \][/tex]

Now, to solve for [tex]\( t \),[/tex] we divide both sides by 16:

[tex]\[ t^2 = \frac{320}{16} \]\[ t^2 = 20 \][/tex]

To find [tex]\( t \),[/tex] we take the square root of both sides:

[tex]\[ t = \sqrt{20} \][/tex]

Now, let's simplify [tex]\( \sqrt{20} \):[/tex]

[tex]\[ \sqrt{20} = \sqrt{4 \times 5} \]\[ \sqrt{20} = \sqrt{4} \times \sqrt{5} \]\[ \sqrt{20} = 2\sqrt{5} \][/tex]

Approximately, [tex]\( \sqrt{5} \)[/tex] is around 2.24, so [tex]\( 2\sqrt{5} \)[/tex] is approximately [tex]\( 2 \times 2.24 \),[/tex] which is approximately 4.48.

So, it will take approximately 4.5 seconds for the rock to reach the river.

Therefore, the correct answer is option D: 4.5 seconds.
