melody had 120 stamps.

and she gave Jeremy 30 stamps .

so she had 90 stamps now.

after she gave Jeremy 30 stamps,she had twice as much as him.

so 90 is 45+45 .other way 45 is half of 90.

so Jeremy had 45 stamps now.

they have altogether 90+45=135 stamps.

the answer is 135

By creating and solving an algebraic equation, we learn that Jeremy started with 60 stamps and Melody started with 180 stamps. Therefore, they originally had 240 stamps combined.

We'll use algebra to solve this. Let's let Jeremy's number of stamps be represented by J. According to the information, Melody had 120 more stamps than Jeremy before she gave him 30, so she had J + 120 stamps. After transferring the 30 stamps, she has J + 120 - 30 stamps, which simplifies to J + 90 stamps. According to the problem, this amount is twice the amount Jeremy has after receiving the 30 stamps (J + 30). So, we can set up this equation: 2(J + 30) = J + 90.

Solving this equation gives J = 60. That means Jeremy started with 60 stamps. Therefore, Melody started with 60 + 120 = 180 stamps. The total number of stamps both had originally is 60 + 180 = 240 stamps.

2/12 does not = 3/18

Thus, NEITHER is the answer.

Answer:

Width __6___ cm

Length __12__ cm

Step-by-step explanation:

hello :

x : the width   and y : Length    P : the  perimeter

P=2(x+y )        but : P=36cm  and : y = 2x

36 = 2(x+2x)

36 = 2(3x)

6x =36   so : x=6 cm   and y = 2×6=12cm

Step-by-step explanation:

If breadth is b,then length will be 2b,so

Perimeter=36

2(2b+b)=36

3b=18

b=6,so,l=2×6=12

So,length is 12 and breadth is 6,

Correct option is A,  f(x) -2 has changed the parent function f(x) = (0.5)x to its new appearance.

The parent function f(x) = log5x has been modified by reflecting it over the x-axis, extending it vertically by a factor of three, and moving it down by three units.

In the picture below you can see the blue line is the graph of the function

f(x) = log(5x) and the green line is the graph of the function

g(x) = log[5(x + 4)] - 2

Since the function f passes at point (2, 1), we must reduce it by 2 units to ensure that it also passes at position (-2, -1). To do this, we add 2 to the function f.

We only need to add 4 to the variable x to have the function go left when we obtain log(5x) - 2.

The function shifts to the left when you add a number to x;

The function moves to the right when you remove a number from x;

The function increases when you add a number to it;

The function decreases when you take a number away from it.

Then we get a function g(x) = log[5 (x + 4)] - 2.

Answer:

It's 3 simple rise/run so 9/3

Answer:

28cm

Step-by-step explanation:

To calculate the area of this shape, we need to seperate it into two shapes.

We see that the length of the top shape is 2 CM.  Since the top shape is a square, we know it is a 2x2 shape (because two of the other sides are 2cm.)  The area of the top shape, the square, can be found by performing the formula for calculating area (length x width).  2 x 2 = 4 (duh, haha).  Now, we need to find the area of the bottom shape.  Since we're separating them into two shapes, we need to subtract the length of the first shape and this one.  4 x 6 (the area formula) will give us 24.  Now, we need to add our two shapes to get the area of the entire shape.  24 cm + 4 cm = 28 cm.

The measure of the reference angle is: \($$\cos (\theta)=\frac{\sqrt{3}}{2}$$\)

The reference angle of an angle is the smallest acute angle between the terminal arm of a quadrant and the x-axis.

Given that:

\($$\theta=\frac{11 \pi}{6}$$\)

First, we convert to degrees

\(& \theta=\frac{11 \pi}{6} * 180 \pi \\\)

\(& \theta=\frac{11}{6} * 180 \\\)

\(& \theta=11 * 30 \\\)

\(& \theta=330^{\circ}\)

\($$\alpha=30$$\)

Hence, the measure of the reference angle Is: \($30^{\circ}\alpha=30\)$ means that the reference angle is in the first quadrant \($\theta=330^{\circ}$\) means that this angle is in the fourth quadrant

In the first and the fourth quadrants,

\($$\cos (\theta)=\cos (\alpha)$$\)

Substitute \($\alpha=30$\)

\($$\cos (\theta)=\cos (30)$$\)

Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute. Fill in the blank with the amount of water in liters that is in tank a at the given time

How much water is in the tank

after 4 minutes?

How much water is in the tank after 80 minutes ​?

Answer:

How much water is in the tank

after 4 minutes?

= 160 liters

How much water is in the tank after 80 minutes ?

= 844 liters

Step-by-step explanation:

Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute.

How much water is in the tank

after 4 minutes?

1 minute = 9 liters

4 minutes = x

x = 9 liters × 4

x = 36 liters

The amount of water in the tank after 4 minutes

= 124 liters + 36 liters

= 160 liters

How much water is in the tank after 80 minutes ?

1 minute = 9 liters

80 minutes = x

x = 9 liters × 80

x = 720 liters

The amount of water in the tank after 4 minutes

= 124 liters + 720 liters

= 844 liters

The missing angle of the diagram is expressed as; x = 70°

An angle is usually measured with reference to a circle with its center at the common endpoint of the rays. Hence, the sum of angles at a point is always 360 degrees

Now, we are given a point with three angles where one is unknown and the other two are known. Thus, by the sum of angles about a point, they will sum up to 360 degrees.

Thus;

x + 160 + 130 = 360

x + 290 = 360

x = 360 - 290

x = 70°

The point 4 units along the curve (in the direction of increasing t) from P exists as t = ln |L/2 + 1|.

When a particle's position in space is represented as a function of time by a vector-valued function, the arc-length function calculates the particle's travel distance as a function of time.

The length of an arc is the separation of two locations along a segment of a curve. Curve rectification is the process of measuring an irregular arc segment's length by simulating the section as a network of connected line segments. A rectifiable curve can be broken down into a finite number of segments.

(a) Let the given function be r(t) = \(e^t\) sin t i + √2 \(e^t\) k

To find the arc length of the function, we have:

\(& \mathrm{r}^{\prime}(\mathrm{t})=\mathrm{e}^t \\\)

\(& \mathrm{r}^{\prime}(t)=(\cos t+\sin t) e^t+(\cos t-\sin t) e^t+\sqrt{2} e^t \\\)

\(& \left|r^{\prime}(t)\right|=\sqrt{\left[(\cos t+\sin t) e^t\right]^2+\left[(\cos t-\sin t) e^t\right]^2+\left(\sqrt{2} e^t\right)^2}\)

simplifying the above equation, we get

\(& =\sqrt{\left(4 e^{(2 t)}\right)} \\\)

\(& =2 \mathrm{e}^t\)

(b) We have the arc length function, L to be the integral from 0 to t, so:

\($& L=\int_0^t 2 e^v \\\)

simplifying the above equation, we get

\(& L=2 e^t-2 e^0 \\\)

\(& =2 e^t-2 \\\)

\(& L=2\left(e^t-1\right) \\\)

simplifying the above equation, we get

\($& L / 2=e^t-1 \\\)

\(& L / 2+1=e^t\)

\(e^t\) = L / 2+1

t = ln |L/2 + 1|

The complete question is:

A. Find the arc length function for the curve measured from the point P in the direction of increasing t and then reparametrize the curve with respect to arc length starting from P.

To find,

Choose the correct option.

Solution,

For a parallelogram, the opposite angles are equal. ATQ,

(6x-21)° = (4x+11)°

Taking like terms together,

6x-4x = 21 + 11

2x = 32

x = 16

∠C = (6x-21)° = 6(16) -21 = 75°

So, ∠A = 75°

So, ∠A = ∠C = 75°. Hence, the correct option is (B).

y₂ = m(x₂ - x₁) + y₁ is an equivalent equation solved for y₂, using the concept of linear equation.

A linear equation has the following standard form: ax + by + c = 0.

Here, variables x and y and constants a, b, and c are used.

Also, a ≠ 0, and b ≠ 0.

For linear equations, the slope-intercept formula is: y=mx+b

Where m stands for the line's slope and b represents the y-intercept.

The three types of linear equations are point-slope, slope-intercept, and standard form.

When an algebraic equation is graphed, it always produces a straight line since each term has an exponent of 1 or 0. This is known as linear equations.

given that,

The slope m, of a linear equation can be found using the formula:

m = (y₂-y₁)/(x₂-x₁)
