Write an equation of the parabola shown. (0,4) (-5, 1.5)

Answer:

I'll assume m2 is m^2

m = ±4

Step-by-step explanation:

1.  m = ±4  m^2 = 16  YES.  Both -4 and 4, when squared, are equal to 16

2.  m = 4   This also works, but it doiesn't allow for the possibility that m is a -4

3.  m = ±8  8^2 = 64  and (-8)^2 = 64 Don't work.

4.  m = 8   8^2 = 64  Doesn't work.

Doug dives a total distance of 6.8 meters from the platform to the bottom of the sea.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given that a Doug dives from a platform that is 5 meters above the water.

His dive takes him 1.8 meters below the surface of the water.

To determine the total distance Doug dived, add the height of the platform above water and the distance he dived below water.

= (5 + 1.8) meters.

= 6.8 meters.

Thus, Doug dives a total distance of 6.8 meters from the platform to the bottom of the sea.

Answer: (-2, -2)

Step-by-step explanation:

Since both equations are set equal to y,

[tex]2x+2=-\frac{1}{2}x-3\\\\\frac{5}{2}x=-5\\\\x=-2\\\\\implies y=2(-2)+2=-2\\\\\therefore (x,y)=(-2, -2)[/tex]

The equation the function after the transformation is  g(x) = -4x² - 8

The equation of the function is given as

f(x) = x²

The sequence of transformations is given as follows:

When the above transformations are combined, we have:

So, we have

g(x) = -4(x² + 2)

Expand

g(x) = -4x² - 8

Hence, the function g(x) is g(x) = -4x² - 8

Answer:

Step-by-step explanation:

answers are in the picture above

The scale factor for the graph will be 3 and there will be enlargement.

The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. We can use the following points to know about enlargement.

A(1, 1) ⇒ A'(3, 3)

B(2, 1) ⇒ B'(6, 3)

C(1, 2) ⇒ C'(3, 6)

D(2, 2) ⇒ D'(6, 6)

Now, to find the scale factor, simply divide the Point' with the original Point. Use any number.

A'(3, 3)/(A(1, 1)) = 3

B'(6, 3)/(B(2, 1)) = 3

C'(3, 6)/(C(1, 2)) = 3

D'(6, 6)/(D(2, 2)) = 3

which shows that the scale factor is 3.

Answer:

The answer is C.

Answer: 5

Step-by-step explanation: Substitute the value of the variable into the expression and simplify

The given the initial equation

we can determine the part of the graph to be shaded if the equation changes to the inequality:

If we make y the subject of the formula, such that

Then we can put in the values of x and y at (0,0)

so that

we can see that the expression is false because 0 is not greater than 1

Hence, we will shade away from the origin this means that we will shade above the line

The graph is shown below

So for question B

We will shade above the line

Question C

The points on the line are not included because the inequality does not include an equal sign

Answer:

A.    Bank B

Step-by-step explanation:

First the formulae necessary to calculate compound and simple interest

P = principal = amount deposited

r = interest rate as a decimal (i%  interest => r = i/100)

t = number of years

n = number of times compounded

[tex]\text{Compound Interest }= P\left(1 + \dfrac{r}{n}\right)^{nt} - P[/tex]

In this case, we have P = 800
r = 8/100 = 0.08
n = 12 since the interest is compounded monthly
t = 2 years

So compound interest

[tex]CI = 800\left(1 + \dfrac{0.08}{12}\right)^{12 \times 2} - 800\\\\CI = 800(1.00667)^{24} - 800\\\\\\CI = 938.31 - 800\\\\CI = $138.31[/tex]

For Bank B, the interest is calculated at 9% annually and the interest is given by the formula
SI = P x r x t
SI = 800 x 0.09 x 2    (r = 9%/100 = 0.09)

SI =  $144.00

So depositing in bank B is preferred

The data in the question will be represented by a geometric sequence given by 3 (2) ⁿ⁻¹.

A geometric sequence is defined as the sequence in which the ratio between the consecutive terms of the sequence remains constant. The ratio is known as common ratio. The nth term of geometric sequence is written as a (r)ⁿ⁻¹ where a is the first term, r is the common ratio and n is the number of terms. We know from the question that the time in minutes Aurora takes to complete the task forms a sequence as 3, 6, 12, 24.....

The common ratio of this sequence is given by 6/3 = 2. The first term being equal to 3. Now, for the nth term the sequence will be represented as

As a result, 4.8 litres of water will be in the fish tank after three minutes if the water release rate is 1.6 gallons per minute.

A linear system is a mathematical representation of a system in systems theory that relies on the application of a linear operator. Compared to nonlinear systems, linear systems often have significantly simpler traits and properties. Linear systems are widely used in automatic control theory, signal processing, and telecommunications as a mathematical abstraction or idealization.

for 0.5 minutes , 0.8 gallons of water is required

To convert to gallons per minute, multiply by 2.

1.6 gallons per minute (0.8 x 2)

Gallons per minute multiplied by three minutes

3.0 minutes = 4.8 liters (1.6 x 3)

The length of the pole is 19.15 feet.

The angle of elevation is created by the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, the angle formed is an angle of elevation.

Given:

Angle made by straight road = 15°

Angle of elevation of the sun = 57°

Length of the shadow = 75 feet

∠ACB = 90° - 57° = 33°

∠CAB = 57° - 15° = 42°

Using Sine Law to find BC i.e.length of the pole.

[tex]\frac{BC}{sin A} = \frac{AB}{sin C}[/tex]

[tex]\frac{BC}{sin 42} = \frac{75}{sin 33}[/tex]

[tex]BC= \frac{75sin 42}{sin 33}[/tex]

BC ≅ 19.15 feet (to the nearest hundredth.)

The area of the circle of radius r centered at the origin is π[tex]a^{2}[/tex]

Since the circle is symmetrical in relation to the x and y axes, we can calculate the area of a quarter of a circle and multiply it by 4 to get the entire circle's area.

The equation y y = + mn [a 2 - x 2] must be solved.

Y = [a 2 - x 2] = a [1 - x 2 / a 2] is the equation for the upper semicircle (y positive).

Using integrals, we can calculate the area of the circle's top right quarter as shown below.

(1 / 4) Circle's area is equal to 0a a [1 - x 2 / a 2]. dx

Let's replace x/a with sin t to make sin t equal to x/a, dx equal to a cos t dt, and the area is given by

The formula for area of a circle is (1 / 4) Area of circle = 0/2 a 2 (1 - sin2 t) cos t dt

Now that t can range from 0 to /2, we utilize the trigonometric identity [1 - sin2 t] = cos t, which equals (1 / 4) Circle area equals 0/2 a 2 cos2 t dt.

To linearize the integrand, use the trigonometric equation cos2 t = (cos 2t + 1) / 2;

(1 / 4) Circle's area is equal to 0/2 a (cos 2t + 1) / 2 dt.

the integral (1 / 4) be evaluated. Circle's area is equal to (1/2) a2 [(1/2) sin 2t + t]. 0π/2\s= (1/4) π a 2

The circle's entire area is calculated by multiplying by 4.

Area of a circle is equal to 4 * (1/4) a 2 a 2. additional references on integrals and calculus applications.
