Write an exponential function whose graph contains the points (1, 6) and (0, 2).

Answers

Answer 1

Answer:

y = 2 [tex](3)^{x}[/tex]

Step-by-step explanation:

The exponential function is of the form

y = a [tex](b)^{x}[/tex]

To find a and b substitute the given points into the equation

Using (0, 2), then

2 = a [tex](b)^{0}[/tex] ⇒ a = 2

Using (1, 6), then

6 = 2 [tex](b)^{1}[/tex] ⇒ b = 3

Equation is y = 2 [tex](3)^{x}[/tex]

what is the equation of (4,10),(6,11) in standard form?​

Answers

ANSWER

The standard form is:

[tex]x - 2y = - 16[/tex]

EXPLANATION

The given line passes through (4,10)and (6,11).

The slope of this line is

[tex]m = \frac{11 - 10}{6 - 4} [/tex]

[tex]m = \frac{1}{2} [/tex]

The equation is given by the formula,

[tex]y-y_1=m(x-x_1)[/tex]

We plug in the first point and the slope to get.

[tex]y-10= \frac{1}{2} (x-4)[/tex]

[tex]2y - 20 = x - 4[/tex]

[tex]x - 2y = - 20 + 4[/tex]

An international equity mutual funds includes, american stock ,japanese stock,german. Stock , british stock in the ratio of 27:19:14:11 respectively. If its current holdings of german stocks are valued at us$238 millions what are the values of its holdings in the securities of other 3 countries

Answers

Give me BRAINLIEST please

let's say the total holdings for the company, or namely the total quantity for the ratios is say hmmm "x", and we were to split "x" in quantities of 27:19:14:11 ratio, what we do is, we simply divide "x" by (27+19+14+11), and then distribute accordingly.

so, if we divide the total amount like that, we end up with fragments of the total, and each ratio gets so many fragments.

so, we know the German stock or that ratio gets $238 millions, and in those 238, since it's on a 14 ratio, there are 14 of those fragments of the total, how much is a fragment anyway?  well, simply how many times does 14 go into 238?  238 ÷ 14 = 17.

well, since we know the whole total of the holdings was split in fragments of 17, let's simply distribute accordingly.

which of the following statements best describes midpoint of a line segment? 1. point at end of line segments 2. a point halfway between the endpoints of a line segments 3. it its any point on a line segments 4. it is the x-coordinate of any point on a line segment.

Answers

Hello!

The answer is:

2. A point halfway between the endpoints of a line segment.

Why?

The midpoint of a line segment, is a point that divides the line segment into two equal length sides, no matter the length of the segment, the midpoint will always cut the segment into two equal length sides

The midpoint is an ordinary point located in the middle of the line segment. The x-coordinate of the midpoint is halfway between the x-coordinates of the beginning and the end of the segment. The y-coordinate of the midpoint is halfway between the y-coordinates of the beginning and the end of the segment.

Hence, the correct option is:

2. A point halfway between the endpoints of a line segment.

Have a nice day!

Midpoint refers to point in the mid. The midpoint of a line segment is given as: Option 2: A point halfway between the endpoints of a line segment.

What does a midpoint mean?

Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.

What is a line segment?

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

If you walk halfway between the endpoints of a line segment, you'll reach to its mid, and thus, the midpoint of a line segment can be reached by walking halfway between its end points.

Thus,

The midpoint of a line segment is given as: Option 2: A point halfway between the endpoints of a line segment.

What is the equation of the line that passes through (7,4) and (4,-2)?
O y= 2x - 10
O y=-2x - 10
O y=-2x + 18
y= 2x + 18​

Answers

Answer:

y = 2x - 10

Step-by-step explanation:

First, we find the slope.

m = slope = (y2 - y1)/(x2 - x1) = (-2 - 4)/(4 - 7) = -6/(-3) = 2

Now we use the slope in the slope-intercept form of the equation of a line.

y = mx + b

y = 2x + b

We use the coordinates of one of the given points for x and y, and we solve for b. Let's use the point (7, 4), so we have x = 7 and y = 4.

4 = 2(7) + b

4 = 14 + b

Subtract 14 from both sides.

-10 = b

Now we replace b with -10.

Split 90 into two parts so that one part is four times the other part.

Answers

Answer:

can you help me with my answer when your done on my page? vvvvv

Step-by-step explanation:

1. **Separating 90 into Two Parts:**

  - The smaller part is [tex]\( 18 \)[/tex] and the larger part is [tex]\( 72 \)[/tex].

2. **Sum of Three Consecutive Integers:**

  - The three integers (in order) are [tex]\( 17, 18, \)[/tex] and [tex]\( 19 \)[/tex].

1. **Separating 90 into Two Parts:**

  - Let's denote the smaller part as [tex]\( x \)[/tex] and the larger part as [tex]\( 4x \)[/tex].

  - According to the problem, the sum of these two parts equals 90: [tex]\( x + 4x = 90 \)[/tex].

  - Combine like terms: [tex]\( 5x = 90 \)[/tex].

  - Divide both sides by 5 to solve for [tex]\( x \): \( x = 18 \)[/tex].

  - So, the smaller part is [tex]\( 18 \)[/tex] and the larger part is [tex]\( 4 \times 18 = 72 \)[/tex].

2. **Sum of Three Consecutive Integers:**

  - Let's denote the smallest integer as [tex]\( x \)[/tex].

  - The next two consecutive integers would be [tex]\( x + 1 \)[/tex] and [tex]\( x + 2 \)[/tex].

  - According to the problem, the sum of these three integers equals 54: [tex]\( x + (x + 1) + (x + 2) = 54 \)[/tex].

  - Combine like terms: [tex]\( 3x + 3 = 54 \)[/tex].

  - Subtract 3 from both sides: [tex]\( 3x = 51 \)[/tex].

  - Divide both sides by 3 to solve for [tex]\( x \): \( x = 17 \)[/tex].

  - So, the three consecutive integers are [tex]\( 17, 18, \)[/tex] and [tex]\( 19 \)[/tex].

The complete question is here:

Now remove the absolute values since x>1.

a hollow cylindrical iron pipe with external and internal radii 8cm and 6cm respectively and length 35 cm is melted and recast into a solid wire of thickness 2.8 cm .find the length of wire.

Answers

Answer:

[tex]500\ cm[/tex]

Step-by-step explanation:

step 1

Find the volume of hollow cylinder

[tex]V=\pi (r2^{2}-r1^{2})h[/tex]

we have

[tex]r2=8\ cm[/tex]

[tex]r1=6\ cm[/tex]

[tex]h=35\ cm[/tex]

substitute

[tex]V=\pi (8^{2}-6^{2})(35)[/tex]

[tex]V=\pi (28)(35)[/tex]

[tex]V=980\pi\ cm^{3}[/tex]

step 2

we know that

The wire is a solid cylinder with the same volume of the hollow cylinder

so

[tex]V=\pi r^{2}h[/tex]

we have

[tex]V=980\pi\ cm^{3}[/tex]

[tex]r=2.8/2=1.4\ cm[/tex] ----> the radius is half the diameter (thickness)

substitute and solve for h

[tex]980\pi=\pi (1.4)^{2}h[/tex]

[tex]980=(1.96)h[/tex]

[tex]h=980/(1.96)=500\ cm[/tex]

Identify the vertex of the graph Tell whether it is a minimum or a maximum​

Answers

Answer:

(1,2)  maximum

Step-by-step explanation:

The vertex is the the point on the graph where the graph does a "u-turn".

this point can either represent the maximum value or the minimum value depending on which way the graph is facing.

In this case, the graph looks like an "n" (as opposed to a "u").

We can clearly see that the point where the graph makes a U-turn is (1, 2)

we can also see that no part of the graph extends above this point, hence this point represents the maximum value which y could possibly be.

Hence (1,2) is maximum

Issof claims that the scale factor is 1/2. Which statement about his claim is correct

Answers

Answer:

He is incorrect because the scale factor is 1/3.

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Triangles CA'B' and CAB are similar

The pre-image is the triangle CAB

The image is the triangle CA'B'

therefore

The scale factor is equal to

CB'/CB

we have

CB'=2 units

CB=2+4=6 units

substitute

CB'/CB=2/6=1/3

therefore

He is incorrect because the scale factor is 1/3.
