b) a rule for congruence mapping that reflects a figure across the y-axis

1. The value of x in the triangle is B. 22.5°.

2. The value of x in the triangle is B. 22.5°.

3. The value of the limit illustrated is D. 32

1. It should be noted that the total angle in a triangle is 180°. The three angles given are illustrated as:

Angle 1 = 3x

Angle 2 = x + 30°

Angle 3 = 180° - 120° = 60°

The value of x will be:.

3x + x + 30 + 60 = 180

4x + 90 = 180

4x = 180° - 90°

4x = 90°

x = 90/4.

x = 22.5°

2. Note that the question was repeated. Therefore, the answer is illustrated above The value of x is 22.5°.

3. x³ + 7x² - 4

when x = 2

x³ + 7x² - 4

= 2³ + 7(2)² - 4

= 8 + 28 - 4

= 32

Answer:

84 people

Step-by-step explanation:

14 percent means that for each 100, there are 14 of something.

This is the most common method to calculate 14% of 600. 600 is the Whole, 14 is the Percent, and the Part is what we are calculating. Below is the math and answer to "What is 14% of 600?" using the percent formula.

Percent Formula:

(Whole × Percent)/100 = Part

(600 × 14)/100 = 84

14% of 600 = 84

Answer:

Weight on Mars:  1,475.32 kg

Step-by-step explanation:

The formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2.

If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

Mass is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram.

Given,

The mass of a space rover is 3900 kg.

We need to check what is its mass in Mars.

The mass of space rover  in Mars will also be same 3900 kg because the mars is same quantity it wont change according to place or time, it remains constant. Where as weight would be changed.

The mass of the object is always constant, anywhere it is on the Earth or Moon or any other planet.

Hence, If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

The percentage of puffin eggs that hatch given in decimal form by the quadratic function, f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61, gives;

a. At 51 °F, 1.5% of the eggs will hatch

b. The temperature at which the maximum percentage of puffin eggs will hatch is approximately 49.5 °F

The maximum percentage of eggs that hatch is approximately 91.8 %

A quadratic function is a polynomial of the second degree (degree 2) such that the highest power of the variables in a quadratic function is 2

The quadratic function is presented as follows;

f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61

Where;

f(x) = The percentage of the eggs that hatch

x = The mean sea surface temperature of the area in degrees Fahrenheit

a. The percentage of the eggs that will hatch at 51° is therefore;

f(51) = -0.379•(51 - 46)² + 2.62•(51 - 46) - 3.61 = 0.015

The percentage of the eggs that hatch at 51° d is f(51) = 0.015 × 100% = 1.5%

b. The temperature for which the percentage of hatched puffin eggs is a maximum, is given by the maximum value of the quadratic function as follows;

At the maximum value of the quadratic function, f(x) = a•x² + b•x + c, we have;

x = -b/(2•a)

Therefore, where we have;

f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61

At the maximum value;

x - 46 = -2.62/(2×(-0.379)) = 1310/379

Which gives;

Second part;

The percentage of eggs that hatch at the temperature that gives the maximum percentage of eggs is the maximum percentage of eggs, which is found as follows;

f(46 + 1310/379) = -0.379•(1310/379)² + 2.62•(1310/379) - 3.61 ≈ 0.9179683

The maximum percentage of puffin eggs is therefore;

By applying the distributive property of multiplication, the students that are correct in their approach to solving the problem are: Nico, Raj and Sandra.

In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 5/2 as follows:

2/5(5 + x) = 8

Multiplying both sides by 5/2, we have:

5/2 × 2/5(5 + x) = 8 × 5/2

5 + x = 40/2

5 + x = 20

Subtracting 5 from both sides, we have:

5 + x - 5 = 20 - 5

x = 15

In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 1/2 and then 5 as follows:

2/5(5 + x) = 8

Multiplying both sides by 1/2, we have:

1/2 × 2/5(5 + x) = 8 × 1/2

1/5(5 + x) = 4

Multiplying both sides by 5, we have:

5 × 1/5(5 + x) = 4 × 5

5 + x = 20

Subtracting 5 from both sides, we have:

5 + x - 5 = 20 - 5

x = 15

In order to open the bracket and isolate the variable x, we would apply the distributive property of multiplication:

2/5(5 + x) = 8

2/5 × 5 + 2/5 × x = 8

2 + 2x/5 = 8

Subtracting 2 from both sides, we have:

2 - 2 + 2x/5 = 8 - 2

2x/5 = 6

Multiplying both sides by 5/2, we have:

5/2 × 2x/5 = 5/2 × 6

An integer is the number zero, a positive natural number or a negative integer with a minus sign. The negative numbers are the additive inverses of the corresponding positive numbers.

Given:

At 2 a.m. temperature = -3F

Then temperature decreased 12°F = -12 F

and then increase  7°F = +7F

The meaning of vertical intercept in this context can be inferred from the options to mean that the helicopter took off from a height of 50 ft.

In a linear problem or a graph, the vertical intercept, which is also known as the y-intercept, refers to the value of y when the value of x is 0.

Assuming y in this problem refers to the height and x refers to the minutes, the vertical intercept would be the height at 0 minutes.

The rate of the water being pumped into the tank is 289,753 cm3/min

d = 4m

∴ r = 2m

h = 6m

Therefore r = h/3

The formula for the volume of the cone is:

V=(1/3)π•r2h

substitute:

V=(1/3)π (h/3)2h

V=(1/27)π h3

Derive both sides with respect to time:

dV/dt = (1/9) π h2• dh/dt

When h= 2 meters = 200 cm when dh/dt = 20

dV/dt = (1/9) π (200)2• (20)

dV/dt = (800,000/9) π ~ 279,252.68

Meaning the volume of water is increasing at a rate of 279,252.68 cm3/min.

However, it's leaking out at a rate of 10,500 cm3/min. Therefore the rate of the water being pumped into the tank is:

The equation for the line parallel to y=1/4x+1 that passes through the point (6,-2) is x-4y=14 as the slope for both lines are equal and using slope-point form of equation.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

The equation of a straight line that passes through a given point and is inclined at a specific angle to the x-axis can be found using the point slope form.

Here,

The slope for the line will be 1/4 and the given points will be (6,-2) so the equation for the line is

y-y1=m(x-x1)

y+2=1/4(x-6)

4y+8=x-6

x-4y=14
