Answer:

There is one solution.

Step-by-step explanation:

y=2x+2

y=x-1

So 2x+2 = x-1

x = -3

So y = -4

On a circle with a radius of 4 and center at (0, 0), to find the x and y coordinates at an angle of 180 degrees (or π in radian measure), we can use the trigonometric functions.

At 180 degrees, the x-coordinate will be 0, as it lies on the y-axis. The y-coordinate can be found by using the sine function.  Using the equation y = r * sin(θ), where r is the radius and θ is the angle in radians, we can substitute the values. In this case, r is 4 and θ is π (since 180 degrees equals π radians).

Therefore, the x-coordinate is 0 and the y-coordinate is 4 * sin(π) = 0. So, the x-coordinate is 0 and the y-coordinate is also 0.

Answer:

Ishaan is 21. Christopher is 7.

Answer:  Ishann is 21 years old.

Step-by-step explanation:

In this situation, we will represent Ishaan age by the variable  y and we will represent Christopher's age by x.

Ishaan is 3 times as old as Christopher and that can be represented by the equation,   y = 3x  

He is also 14 years older, and it can also be represented by the equation,  

y = x + 14.  

y= 3x

y = x + 14  

Using both equations, substitute the value of y in one of the equations into the other.

x + 14 = 3x                   Solve for x .

-x           -x

 14 = 2x  

  x = 7  

This means that Christopher is 7 years old.

To solve for Ishaan's age , input the value of x into one of the equations.

y = 3(7)

y = 21.

In the study that seeks to determine the effect of postmenopausal hormone use on mortality, the explanatory variable is postmenopausal hormone use, and the response variable is mortality.

The explanatory variable, also known as the independent variable, is the factor being manipulated or studied to see its effect on the response variable. In this case, it is postmenopausal hormone use, which is being investigated to understand its impact on mortality.

The response variable, also known as the dependent variable, is the outcome being measured or observed as a result of the explanatory variable. This study is the mortality rate among postmenopausal women. The researchers are trying to determine whether postmenopausal hormone use has an effect on mortality, making it the response variable.

Answer:

The original cost for 1 pound of coffee is $4.50, and Gabriel wants to buy 4 pounds, so the total cost without the coupon would be:

4 pounds x $4.50/pound = $18

With the coupon, Gabriel can subtract $2 from the final amount, so the total cost with the coupon would be:

$18 - $2 = $16

Therefore, Gabriel would have to pay $16 to buy 4 pounds of coffee with the coupon.

To write an expression for the cost to buy p pounds of coffee, we can use the formula:

cost = price per pound x number of pounds - coupon

If Gabriel buys at least one pound of coffee, then the expression would be:

cost = $4.50p - $2

So the cost to buy p pounds of coffee can be calculated by plugging in the desired value for p into this expression.

Step-by-step explanation:

Coefficients are just the numbers that accompany the variables. So if you have any number, let's take 4, and put it next to an x: 4x, 4 will be your coefficient.

Hence , bob's average distance and speed will be more than the alice's average distance and speed .

We have given a function f (t) = 7.2t which represents the distance walked by bob over his bike.

Differentiating f(t) with respect to t , we get

        f'(t) = 7.2

On differentiating distance with respect to time , we get speed

         s = 7.2

It is also given that function f (t) = 5.9t which represents the distance walked by alice.

Differentiating f(t) with respect to t , we get

          f'(t) = 5.9

On differentiating distance with respect to time , we get speed

           s = 5.9

We can see that the average distance of bob is more than the average distance of alice .

Bob speed will be the more than same alice speed.

Answer: The given equation is Y = -10x + 300.

The rate of change of this equation refers to the rate at which Y changes as x changes. This is the same as the slope of the line represented by the equation.

The equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. So, we can see that the slope of the line is -10. This means that for every one unit increase in x, y decreases by 10 units.

Therefore, the rate of change of Y with respect to X is -10.

Answers:

u = 18

v = 20

========================================================

Work Shown:

The leg YZ is congruent to the left FH

This means YZ = FH and that leads to u+v-18 = 10u-8v

The hypotenuse ZX is congruent to the hypotenuse HG

This means ZX = HG and we get the equation 14v-14u+32 = v+u+22

----------------------

The system of equations we have so far is

u+v-18 = 10u-8v

14v-14u+32 = v+u+22

Let's get the equations into standard form

Start with the first equation

u+v-18 = 10u-8v

u+v = 10u-8v+18

u+v-10u+8v = 18

-9u+9v = 18

-9(u-v) = 18

u-v = 18/(-9)

u-v = -2

Note how we can solve for the variable u to get

u = v-2

which we'll use later

----------------------

Let's get the other equation into standard form as well

14v-14u+32 = v+u+22

14v-14u-v-u = 22-32

-15u+13v = -10

Now plug in u = v-2 and solve for v

-15u+13v = -10

-15(v-2) + 13v = -10

-15v+30+13v = -10

-2v+30 = -10

-2v = -10-30

-2v = -40

v = -40/(-2)

v = 20

Which means,

u = v-2

u = 20-2

u = 18

Answer:

h = 20 cm

Step-by-step explanation:

Base Area = 18 cm * 5 cm = 90 cm²

Volume = 600 cm³

Arranging the formula for h:

h = \(\frac{3(Volume)}{base Area}\)

h = \(\frac{3(600)}{90}\)

h = \(\frac{1800}{90}\)

h = 20 cm

Answer:

64 - (-16/3) = 208/3

Step-by-step explanation:

I think the problem may be written incorrectly. For this to be correct, it must be 64- (-16/3) = 208/3.

To get 203/3 you have to find a common denominator because in order to subtract (or add) fractions, they must have the same denominator.

However, 64 does not have the same denominator as -16/3!!

We can write 64 as 64/1, and to give it the same denominator as -16/3, we need to multiply the denominator by 3

BUT we have to do the same thing to the numerator!!! We can't only change the denominator. If one changes, the other has to change too.

So lets multiply the numerator and denominator by 3. 64 x 3 = 192

1 x 3 = 3

Now we have 192/3

Subtracting a negative number is the same as adding. So instead we can write 192/3 + 16/3

Add 192 and 16 to get 208, so now you have 208/3

The objects are chosen depending on shape, pattern and texture.  The chosen objects are arranged such a way that they also have aesthetic appeal and harmonic configuration.

When choosing items for your still life composition, think about whether their shape, texture, or pattern is more significant.

After selecting your items, the next step is to arrange them in an aesthetically acceptable and harmonic configuration.

Take your time positioning them and move around your composition to try other angles. A changed viewpoint frequently causes a significant compositional shift.

Try to arrange the objects so that some of them overlap to make it apparent which is in front of which.

Create links that guide the viewer's attention around the composition.
