Answer:

x=40

Step-by-step explanation:

What the problem is telling you is that the unlabeled angle is the same as the 70 degree angle. Since all the angles of a triangle add up to 180 degrees. First take 70+70, which equals 140. Now take the 180-140=40 ,so 40 would be the missing angle.

Final answer:

In an isosceles triangle, the angles opposite the congruent sides are congruent. To find the value of x in the triangle, we can set up an equation using the fact that the sum of the angles in a triangle is always 180 degrees. Simplifying the equation, we can find a value for x.

Explanation:

In an isosceles triangle, the angles opposite the congruent sides are congruent. Let's assume that the value of the unknown angle is x.

Since the triangle is isosceles, the other two angles are congruent. Let's call them a and a.

The sum of the angles in a triangle is always 180 degrees. Therefore, we can write the equation: x + a + a = 180.

Simplifying the equation, we get: 2a + x = 180.

Since the other two angles are congruent, we can say that: 2a = 180 - x.

Dividing both sides of the equation by 2, we find: a = (180 - x)/2.

Therefore, the value of x in the triangle is (180 - a)/2.

Step-by-step explanation:

This question is not complete; please find the question attached.

Sales of cell phones at the store is growing at the rate of 3.75% per month which reveals that the monthly sales of cell phone is growing exponentially.

Sales per month will be represented by the growth function,

[tex]f(x)=A(1+\frac{r}{100})^{x}[/tex]

Where f(x) = Monthly sales

A = Sales in the first month

r = rate of increase in the sales

x = Duration or time

Fro the given question,

A = 417,  r = 3.75

So the function showing the monthly sales will be,

Step-by-step explanation:

h(2) = h(2-1) + 1.8

= h(1) + 1.8

= -5 + 1.8

= -3.2

h(3) = h(3-1) + 1.8

= h(2) + 1.8

= -3.2 + 1.8

= -1.4

As per the given expression h(n)=h(n−1)+1.8, then the value of h(3) is -1.4.

In this explanation, we will calculate the value of h(3) using the given recursive formula h(n) = h(n-1) + 1.8 with the initial condition h(1) = -5. We will follow the iterative approach to find the value of h(3) by step-by-step calculations.

We are given the recursive formula h(n) = h(n-1) + 1.8, where h(1) = -5. Let's find the value of h(3) using this formula.

Step 1: Calculate h(2)

To find h(2), we use the recursive formula:

h(2) = h(1) + 1.8

h(2) = -5 + 1.8

h(2) = -3.2

Step 2: Calculate h(3)

Now, to find h(3), we again use the recursive formula:

h(3) = h(2) + 1.8

h(3) = -3.2 + 1.8

h(3) = -1.4

Answer:

b. ellipse; 3x^2 + y^2 + 6x - 8y + 13 = 0

Step-by-step explanation:

thats the answer on edg :)

The point T(-1,4) lies on the ellipse on the graph.

The equation of the ellipse in general form is:

(x/√2)² + (y/√6)² = 1

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The given equation, 4y² + 12x² = 24, can be simplified by dividing both sides by 24 to get:

y²/6 + x²/2 = 1

This is the equation of an ellipse centered at the origin, with a horizontal major axis of length 2√6 and a vertical minor axis of length 2√2.

To identify the graph of the ellipse passing through T(-1,4), we substitute x = -1 and y = 4 in the equation and simplify:

4(4)² + 12(-1)² = 24

64 - 12 = 52

Thus, point T(-1,4) lies on the ellipse.

To find the equation of the translated or rotated ellipse in general form, we can use standard transformations.

Let (h,k) be the center of the ellipse.

Then we have:

(x-h)²/a² + (y-k)²/b² = 1

where a and b are the lengths of the semi-major and semi-minor axes, respectively.

The center of the given ellipse is (0,0), so h = 0 and k = 0.

To determine the values of a and b, we note that a^(2) is the coefficient of x² in the equation, and b² is the coefficient of y².

Thus, we have:

a² = 2 and b² = 6

Taking square roots, we get:

a = √2 and b = √6

Therefore,

The equation of the ellipse in general form is:

(x/√2)² + (y/√6)² = 1

This is the equation of an ellipse with a horizontal major axis of length 2√2 and a vertical minor axis of length 2√6, centered at the origin and rotated counterclockwise by an angle of θ such that tan(2θ) = 4/3.

To find out how many cherries Rachel picked, the mixed numbers are converted to improper fractions, multiplied, and the result is converted back to a mixed number. Rachel picked 3 11/15 pounds of cherries.

The question asks how many cherries Rachel picked, given that Melissa picked 1 3/5 pounds of cherries and Rachel picked 2 1/3 times more than Melissa. To find this out, we need to convert the mixed numbers into improper fractions, multiply and then convert back to a mixed number if necessary.

First, convert Melissa's cherries to an improper fraction: 1 3/5 = 8/5. Next, convert the number of times more Rachel picked: 2 1/3 times more = 7/3. Now, calculate Rachel's cherries: (8/5) * (7/3) = 56/15. Finally, convert 56/15 to a mixed number: 56/15 is 3 11/15. So, Rachel picked 3 11/15 pounds of cherries.

Answer:

exponential function is power

Step-by-step explanation:

because constantly have an exponential function

thanku

Introducing a constant to an exponential function will shift the graph of the function either vertically or horizontally, depending on how the constant is applied.

An exponential function typically has the form [tex]\( f(x) = a \cdot b^x \)[/tex], where [tex]\( a \)[/tex] is the initial value (the value of the function at [tex]\( x = 0 \))[/tex], and [tex]\( b \)[/tex] is the base of the exponential function (the rate at which the function grows or decays).

When a constant is introduced, there are two primary ways it can affect the function:

1. *Vertical Shift*: If the constant is added to or subtracted from the exponential function, it will result in a vertical shift of the graph. For example, if we have a function [tex]\( g(x) = a \cdot b^x + c \)[/tex], where [tex]\( c \)[/tex] is a constant, the graph of [tex]\( g(x) \)[/tex] will be the graph of [tex]\( f(x) = a \cdot b^x \)[/tex] shifted up by c units if [tex]\( c \)[/tex] is positive, or down by [tex]\( c \)[/tex] units if [tex]\( c \)[/tex] is negative.

2. *Horizontal Shift*: If the constant is introduced as an exponent, it will result in a horizontal shift of the graph. For example, if we have a function [tex]\( h(x) = a \cdot b^{(x - d)} \),[/tex] where [tex]\( d \)[/tex] is a constant, the graph of [tex]\( h(x) \)[/tex] will be the graph of [tex]\( f(x) = a \cdot b^x \)[/tex] shifted to the right by [tex]\( d \)[/tex] units if [tex]\( d \)[/tex] is positive, or to the left by [tex]\( d \)[/tex]  units if [tex]\( d \)[/tex] is negative.

It's important to note that the type of shift (vertical or horizontal) depends on the location of the constant in the function. A constant added to or subtracted from the function's value will cause a vertical shift, while a constant added to or subtracted from the input variable [tex]\( x \)[/tex]  (in the exponent) will cause a horizontal shift.

In summary, the introduction of a constant to an exponential function will not change the fundamental nature of the exponential growth or decay, but it will translate the graph of the function either up/down or left/right, depending on how the constant is incorporated into the function.

Answer:

No, they will not meet.

Step-by-step explanation:

For them to meet, their combined distance covered must be equal to or greater than 16 miles

Given;

Claudia can bike at a speed of 8.5 mph

and Brian can ride 11mph

Time = 0.5 hour

Distance = speed × time

Total distance covered by both is;

d = (8.5+11)×0.5 = 9.75miles

Since, the combined distance is less than 16.

d = 9.75 < 16

They will not meet.

Answer: They do not meet.

Step-by-step explanation:

The distance between Claudia's house and her cousin Brian's house is 16 miles.

Claudia's speed is 8.5 miles per hour.

Brian's speed is 11 miles per hour.

If the part from their houses and travel for 0.5 hours, we have that the distance traveled by Claudia is equal to her velocity times the time she is biking, this is:

C = 8.5*0.5 = 4.25 miles.

So Claudia moves 4.25 miles towards Brian's house in this time, this means that Brian needs to move 16 miles - 4.25 miles = 11.75 miles.

Now, the distance that Brian moves is equal to his velocity times the time:

B = 11*0.5 = 5.5 miles

This is smaller than 11.75 miles, so they do not meet if they only bike for half an hour.

The answer is x = 13.

Step-by-step explanation:

first, move the constant to the right and change its sign, (+15)

3.75 x = 63.75 -15

next, subtract the numbers, (65.75 -15)

3.75x = 48.75

then, divide both sides of the equation by 3.75,

final answer, x = 13

Answer:

x = 13

Step-by-step explanation:

to solve this just simply collect the like terms and divide both sides by the coefficient of x

solution

3.75x +15 = 63.75

3.75x = 63.75 -15

3.75x = 48.75

divide both sides by the coefficient of x which is 3.75

3.75x/3.75  = 48.75/3.75

Answer:

the number of caffeine still in his system by 9:00 am is 192 mg.

Step-by-step explanation:

given information

the mass of initial caffein, m₁ = 300 mg

time, t = 9 - 6 = 2 hours

metabolised = 18%/hour = 0.18/h = 0.18 x 300 mg = 54 mg/h

the student metabolised the caffeine 54 mg/h. thus from 6 am to 9 am the caffeine metabolised is

metabolised in 2 hr = 2 x 54

                                 = 108 mg

the remaining caffeine = initial caffeine - metabolised caffeine

                                      = 300 - 108

                                      = 192 mg

Answer:

The correct answer is 138 mg.

Step-by-step explanation:

To understand this problem we must first analyze it.

We know that the student's body metabolizes 18% of the caffeine ingested every hour.

Therefore we can solve that percentage to already have the number of metabolized caffeine per hour:

(300. 18): 100 =

5400: 100 = 54 mg

We now know that the student's body will metabolize 54 mg of caffeine per hour.

The question is much caffeine is still in his system by 9:00 am?

From 6:00 am to 9:00 am we have 3 hours of difference: 3 . 54 = 162

In three hours 162 mg of caffeine were already processed by his body, therefore, it still needs to be metabolized: 300 - 162 = 138 mg.
