a submarine dives 462 feet beneath the surface. it then climes up 250 feet. what is the depth of the submarine now?

Answer:

C

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← where r is the radius

here r = 4, thus

x² + y² = 4², that is

x² + y² = 16 → C

Answer:

C). x^2 + y^2 = 16.

Step-by-step explanation:

The equation of a circle with  center (0, 0) and radius r is

x^2 + y^2 = r^2

So our equation  (with r = 4) is:

x^2 + y^2 = 4^2

x^2 + y^2 = 16.

Answer:

The correct answer is B.

Step-by-step explanation:

In this graph we can see a "Parabola", this is the curve for a second degree polynomial function, and based on "Fundamental theorem of algebra" we can know that this polynomial has 2 roots (they can be real or imaginary).

In this graph, the curve doesn't touch the X axis, so we know that this function has not real root. So both roots are complex

Answer: 10.676 cm

Step-by-step explanation:

We know that ,

The circumference of a circle is given by :_

[tex]\text{Circumference}=\pi d[/tex] , where d= diameter.

Given : Diameter of circle = 3.4 cm

Then Circumference of circle = [tex](3.14)(3.4=10..676\text{ cm}[/tex]

Hence, the circumference of a circle with a diameter of 3.4 cm is 10.676 cm.

Answer:

f(x)=-1 and 15

Step-by-step explanation:

What you do is you put -2 and 2 into the x.

f(x) = -4(-2) + 7 = -1

f(x) = -4(2) + 7 = 15

f(x)=-1 and 15 are your answers.

After substituting the values of x into the function f(x)=-4x + 7, when x = 2 the result is -1, and when x= -2 the result is 15, indicating specific points on the graph of the function.

To evaluate the function f(x) = -4x + 7 for specific values of x, we need to substitute the x values provided into the function.

When x = 2, f(2) = -4(2) + 7 = -8 + 7 = -1.

When x = -2, f(-2) = -4(-2) + 7 = 8 + 7 = 15.

So, f(2) = -1 and f(-2) = 15. These values represent specific points on the graph of the function f(x) = -4x + 7.

Answer:

base is 28 feet squared

height is 25 feet squared

From the conditions given, we set up an equation (1/2) * (h + 3) * h = 350. By solving for h, we find the height of the triangle is 20 feet and the base, which is 3 feet more, is 23 feet.

In this problem, we are given that the base of a triangle exceeds the height by 3 feet and the area of the triangle is 350 square feet. We need to use the formula for the area of a triangle, which is (1/2)bh, where b is the base and h is the height. We can set up an equation from the given conditions: (1/2) * (h + 3) * h = 350. Solving for h, we get h = 20 feet. Therefore, the base b = h + 3 = 20 + 3 = 23 feet. So, the height of the triangle is 20 feet and the base is 23 feet.

Answer:

Since, an airplane descended 4,000 feet before landing.

Now, we have to determine the integer which represents the number of feet, the airplane was above the ground before its descent.

Before the descent, airplane was at the height of 4,000 feet.

And the distance above the ground is represented by the positive integers and distance below the ground is represented by the negative integers.

Since, 4,000 feet is the distance of airplane above the ground.

So, the airplane was +4,000 feet above the ground before its descent.

Final answer:

The graph depicts a logistic growth model, signified by an S-shaped curve, which represents population growth that begins exponentially, slows as resources deplete, and stabilizes at the carrying capacity.

Explanation:

The graph you are referring to seems to describe a logistic growth model, which is characterized by an S-shaped curve. This type of growth is common in populations where initially there is exponential growth due to plenty of resources and few individuals. However, as the population increases, resources become limited, slowing the growth rate; eventually, the population size stabilizes at the carrying capacity of the environment. When categorizing the graph:

Initially, the growth is exponential.

Over time, as resources become scarce, the growth rate decreases.

Finally, growth becomes nearly zero as the population reaches the environment's carrying capacity.

At different time intervals, we can annotate changes in the growth rate:

During the first phase, growth rate increases linearly with the number of individuals (exponential growth).

During the second phase, the growth rate decreases in proportion to the square of the number of individuals.

In the third phase, when carrying capacity is reached, the rate of growth is zero (no net increase in population).

This can be contrasted with the exponential growth model which is represented by a J-shaped curve and shows unbounded growth over time.

Answer:   33

Step-by-step explanation:

The ratio of Adhy's to Ben's is 3:4 so let

Adhy = 3x

Ben = 4x

Since Ben = Adhy + 9

then   4x   =    3x    + 9

-->        x    =  9

So, Adhy = 3x  = 3(9)   = 27

     Ben   = 4x   = 4(9)   = 36

*************************************************************

The ratio of Ben's to Clayson's is 3:5

How do we get Ben's ratio of 3 equal to 36? by multiplying by 12

Ben  :  Clayson

3 x 12    5 x 12

 36          60

So, Clayson = 60

Answer:   [tex]\bold{x=\bigg\{4,-\dfrac{2}{7}}\bigg\}[/tex]

Step-by-step explanation:

7x² - 26x - 8 = 0            

Find two numbers whose product equals (7)(-8) and sum equals -26.

                        -28 × 2 = 56, -28 + 2 = -26

Replace -26x with -28x + 2x:      7x² - 28x + 2x - 8 = 0

Factor the left two terms & right two terms:    7x(x - 4) + 2(x - 4) = 0

Notice that both sides have a common factor of (x - 4)  -->  This is one of the factors.  The other factor is what is on the outside of (x - 4) --> 7x + 2

Rewrite the expression as two factors:   (x - 4)(7x + 2) = 0

set each factor equal to zero and solve for x.

              x - 4 = 0                7x + 2 = 0

                   x = 4                 7x       = -2

                                              x       [tex]=-\dfrac{2}{7}[/tex]

The fraction [tex]\( \frac{2}{3} \)[/tex] results in a repeating decimal [tex]\( 0.\overline{6} \)[/tex], which falls between 0.5 and 1.

Sure, here's a step-by-step explanation:

1. Start with the fraction: We begin with the fraction [tex]\( \frac{2}{3} \)[/tex].

2. Convert to decimal: To convert this fraction to a decimal, divide the numerator (2) by the denominator (3).

[tex]\[ \frac{2}{3} = 0.66666... \][/tex]

The decimal representation of [tex]\( \frac{2}{3} \) is \( 0.\overline{6} \)[/tex], which means the digit 6 repeats infinitely.

3. Determine where it falls between 0.5 and 1: Since the decimal [tex]\( 0.\overline{6} \)[/tex] is greater than 0.5 and less than 1, the fraction [tex]\( \frac{2}{3} \)[/tex] indeed fits the criteria of being a fraction with a repeating decimal between 0.5 and 1.

Answer:

5^12

Step-by-step explanation:

When you have a question where a number is raised to the power of twice you just multiply both exponents. In this case 4x3=12

So 5 to the power of 4 to the power of 3 is 5 to the power of 12

Say the other number is a. The sum is a+P, which also equals 24.

Write it as, a+P=24.

Now subtract P from both sides.

you get, a = 24-P

So, the other number in terms of P is 24 - P

To express the other number in terms of P when the sum of the two numbers is 24, subtract P from 24: Q = 24 - P.

In Mathematics, when you have a sum of two numbers, and you know the value of one number, you can find the other number by subtracting the known number from the total sum.

This is known as solving for a variable.

In this specific question where two numbers have a sum of 24, and if one number is P, the other number can be expressed in terms of P as 24 - P.

It is a simple equation derived from the basic formula: Sum = Number1 + Number2
