Step-by-step explanation

Jennifer and Linda both bought one apple, but they bought different numbers of oranges. Looking at the numbers, we see that Linda bought 2 more oranges than Jennifer (they bought the same number of apples, so disregard apples for now, we will look at them later).

Subtracting Jennifer's cost from Linda's cost, 7.50 - 5.10 = 2.40

So, we know that 2 oranges cost $2.40, so 1 orange will then cost $1.20.

Now we know the cost of 1 orange. So, we can find the price of an apple by finding the cost of 3 oranges. 3 x 1.20 = 3.60. So, Jennifer's 3 oranges cost 3.60, and subtract this cost from the total cost and we find that 1 apple costs $1.50.

Add the price of 1 apple and 1 orange. $1.50 + $1.20 = $2.70

Step-by-step explanation:

The height of Lincoln's face on Mt. Rushmore is approximately 126.56 feet.

To calculate the height of Lincoln's face on Mt. Rushmore, we can use trigonometry and the given angle of elevation.

Let's denote the height of Lincoln's face as 'h'. From the two sightings 800 feet from the base of the mountain, we can form a right triangle.

Using the tangent function, we can set up the following equations:

tan(32°) = h / 800 (for the bottom angle of elevation)

tan(35°) = (h + h) / 800 (for the top angle of elevation, since the distance is the same)

Simplifying these equations, we find:

h ≈ 800 * tan(32°) ≈ 465.03 feet (for the bottom of Lincoln's face)

2h ≈ 800 * tan(35°) ≈ 261.53 feet (for the top of Lincoln's face)

Therefore, the height of Lincoln's face is approximately 465.03 feet, and the total height from the bottom to the top is approximately 261.53 feet.

Step-by-step explanation:

(a)the body temperature of the 1601 lb man will increase by approximately 3.0 °C.(b)the body temperature of the 160 lb man will increase by approximately 2.4 °C.

The specific heat of a human is given as 3.47 J/°C. Using this information, we can calculate the increase in body temperature when a certain number of calories are converted into heat energy. In the first scenario, a 1601 lb man consumes a candy bar containing 287 Cal. In the second scenario, a 160 lb man consumes a roll of candy containing 41.9 Cal. We will calculate the increase in body temperature for each case.

(a) To calculate the increase in body temperature for a 1601 lb man who consumes a candy bar containing 287 Cal, we need to convert calories to joules. Since 1 Calorie (Cal) is equal to 4184 joules, we have:
Energy = 287 Cal × 4184 J/Cal = 1.2 × \(10^6\) J
Now, using the specific heat formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat, and ΔT is the change in temperature, we can rearrange the formula to solve for ΔT:
ΔT = Q / (mc)
Assuming the mass of the man is converted to kilograms, we have:
ΔT = (1.2 × \(10^6\) J) / (1601 lb × 0.4536 kg/lb × 3.47 J/°C) ≈ 3.0 °C
Therefore, the body temperature of the 1601 lb man will increase by approximately 3.0 °C.
(b) For a 160 lb man who consumes a roll of candy containing 41.9 Cal, we repeat the same calculation:
Energy = 41.9 Cal × 4184 J/Cal = 1.75 × \(10^5\) J
ΔT = (1.75 × \(10^5\) J) / (160 lb × 0.4536 kg/lb × 3.47 J/°C) ≈ 2.4 °C
Thus, the body temperature of the 160 lb man will increase by approximately 2.4 °C.

The perimeter of the polygon with vertices Q(-3, 2), R(1, 2), S(1,-2), and T(-3,-2) is 16 units.

Perimeter is a circumferential measure of the figure, for example, the perimeter of a square is the sum of all its sides.

Here,

To find the perimeter of a polygon, we need to add up the lengths of all its sides. In this case, we have a quadrilateral with vertices Q(-3, 2), R(1, 2), S(1,-2), and T(-3,-2).

We can use the distance formula to find the lengths of each side:

Length of QR = √[(1 - (-3))² + (2 - 2)²] =  4

Similarly,

Length of RS= 4

Length of ST= 4

Length of TQ= 4

Therefore, the perimeter of the polygon is 4 + 4 + 4 + 4 = 16

So the perimeter of the polygon with vertices Q(-3, 2), R(1, 2), S(1,-2), and T(-3,-2) is 16 units.

I don’t have an answer for number one but

2) Angle I = 59. From lowest to greatest it goes G,I,H

Answer:

Problem 1
From smallest to largest:
∠y , ∠w, ∠x

Problem 2

m∠I = 39°

Sides from shortest to longest
GH, HI, GI

Step-by-step explanation:

For question 1

The ratios of the sides of a triangle to the sine of the angle opposite them is the same

That means the ratios of the sides to each other is the same as the ratio of the sines of the angles opposite them

Since the sine of an angle increases with increasing angle value, the longest side will opposite the greatest angle measurement and the smallest length will be opposite the smallest angle measurement

So in order from smallest to largest
m∠y < m∠w < m∠x

For question 2

Since three angles of a triangle add up to 180°

Missing angle = 180 - (83 + 58)
= 180 - 141

= 39°

From shortest to longest it would be
Side GH < side HI  < side GI

Range of the value of the game played:To get the range of the value of the game played, we have to find the minimum and maximum possible scores. Minimum score of the game: The minimum score is when both teams play their strongest defense strategy.

For Letran, their strongest defense strategy is the Man-to-man defense and for Mapua, their strongest defense strategy is the Half-court Press defense.Using these defense strategies, Letran can get a score of 45 and Mapua can get a score of 30.Thus, the minimum possible score is 45 + 30 = 75.Maximum score of the game: The maximum score is when both teams play their weakest defense strategy.

For Letran, their weakest defense strategy is the Press defense and for Mapua, their weakest defense strategy is the Man-to-man defense.Using these defense strategies, Letran can get a score of 55 and Mapua can get a score of 40.Thus, the maximum possible score is 55 + 40 = 95.Therefore, the range of the value of the game played is 75 to 95.b) To find the defense strategy in which Letran is weak, we have to see which defense strategy allows Mapua to get the highest score.

The indefinite integral of x^11 sin(3x^(13/2)) dx is -(2/13) * \(x^11 * cos(3x^(13/2)) / (9x^3) + (16/271) * sin(3x^(13/2)) + C\), where C is the constant of integration.

Substituting these into the integral, we get: integral of x^11 sin(3x^(13/2)) dx

= integral of sin(u) * x^11 * (2/39)u^(-9/13) du

= (2/39) integral of sin(u) * x^11 * u^(-9/13) du

Next, we can use integration by parts with u = x^11 and dv = sin(u) * u^(-9/13) du. Solving for dv, we get:

dv = sin(u) * u^(-9/13) du

= (1/u^(4/13)) * sin(u) du

Solving for v using integration, we get:

v = -cos(u) * u^(-4/13)

Now we can apply integration by parts:

integral of sin(u) * x^11 * u^(-9/13) du

= -x^11 * cos(u) * u^(-4/13) - integral of (-4/13) * x^11 * cos(u) * u^(-17/13) du

Substituting back u = 3x^(13/2) and simplifying, we get:

integral of x^11 sin(3x^(13/2)) dx

= -(2/39) * x^11 * cos(3x^(13/2)) * (3x^(13/2))^(-4/13) - (8/507) * integral of x^11 cos(3x^(13/2)) * x^(-3/13) dx + C

Simplifying further, we get:

integral of x^11 sin(3x^(13/2)) dx

= -(2/13) * x^11 * cos(3x^(13/2)) / (9x^3) - (8/507) * integral of x^(-28/13) cos(3x^(13/2)) dx + C

Finally, we can evaluate the last integral using the same substitution as before, and we get:

integral of x^11 sin(3x^(13/2)) dx

= -(2/13) * x^11 * cos(3x^(13/2)) / (9x^3) + (16/271) * sin(3x^(13/2)) + C

Therefore, the indefinite integral of x^11 sin(3x^(13/2)) dx is -(2/13) * x^11 * cos(3x^(13/2)) / (9x^3) + (16/271) * sin(3x^(13/2)) + C, where C is the constant of integration.

Answer:

If f=5 pounds of pressure, l=5.4 feet long

Step-by-step explanation:

Force needed to break a board varies inversely with the length of the board

Let

Force to break the board=f

Length of the board=l

f=k/l

Where k is a constant

If f=9 pounds of pressure and l=3 feet long

f=k/l

9=k/3

Cross product

9*3=k

27=k

If k=27, f=5 pounds of pressure. Find l?

f=k/l

5=27/l

Cross product

5l=27

l=27/5

=5.4

l=5.4 feet long

Using proportions, it is found that the board that requires 5 pounds of pressure to break is 1.67 inches long.

The rule of three is:

9 pounds - 3 feet

5 pounds - x feet

Applying cross multiplication:

\(9x = 3(5)\)
