Tori spends equal amounts of time on homework from each of her subjects. She spends 1 hour altogether on her homework each night. If Tori spends 1/4 an hour on Chemistry. How many subjects does she study?

The equivalent expression using a positive exponent is (5/3)⁴ .

If an expression was created utilizing integer variables, constants, and algebraic operations, it is said to be algebraic (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

A positive expression is given as (3/5)⁻⁸ ÷ (3/5)⁻⁴ .

Using the properties of exponents we can calculate the expression as:

(3/5)⁻⁸⁺⁴ = (3/5)⁻⁴ = (5/3)⁴

Hence the required expression is (5/3)⁴

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 number of months where they will both have same amount in their accounts is 40 months.

From the information given, the function f(t) = 10t + 500 models the amount of money in Abby’s account over time and the function g(t) = 11.25t + 450 models the amount of money in Lexi’s account over time.

It should be noted that the number of years when there value will be the same is:

10t + 500 = 11.25t + 450

Collect like terms

11.25t - 10t = 500 - 450

1.25t = 50

Divide

t = 50/1.25

t = 40

In 40 months, Abby and Lexi will have same amount.

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.

Answer:

5/12

Step-by-step explanation:

answers are in the picture above

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

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)

Therefore, 4.8 litres of water will be in the fish tank after 3 minutes if per minute water released is 1.6 gallons

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.

Answer:

The answer is to this problem is five over three

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.

(x₁, y₁)  (x₂, y₂)

        y₂ - y₁         1 - (-1)          1 + 1            2            1

m = ------------- = ----------- = ------------ = --------- = --------

        x₂ - x₁        -1 - (-5)        -1 + 5           4            2

y - y₁ = m(x - x₁)

y - (-1) = (1/2)(x - (-5))

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.....
