Pls help me with this

Answer:

269.1

Step-by-step explanation:

Graphing is pretty easy. Think of the x and y axis as a number line, you go to the right of 0 you get positive. You go to the left, you get negative. The x axis is just that, the y axis is just like a number line but flipped. You go up for positive and down for negative on the y axis. The middle point is always (0,0). To graph a shape, you just connect the points. To plot positive points you would go right and up. So to plot (8,2), you would go 8 points right on the x axis, then 2 points up on the y axis. Think of Quadrant I as 2 positive points, if both points are positive, plot them there. If you need to plot a negative point then a positive point you would go to Quadrant II. If both of the points are negative, plot them in Quadrant III. If it is a positive point then negative, go to Quadrant IV. Remember, the x axis always comes first. Always go right or left first, then up or down. You determine how many points to go right or left then up or down by the point given. Lets take another example. If you were told to plot (-1,5), that would go in Quadrant II. You would go left 1 and up 5. I explained the concept of the coordinate plane, although, I'm not sure what you mean by coordinate proof. Hope that helped :)

The required number of plants from the function is 509 when there are 27 rows.

Given that,

The function g(x) = 18x+23 represents the total number of plants at the gardening store if there are x rows of plants in the field. What is the value of g(27) is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Number of plants,
g(x) = 18x+23
Since the number of rows is 27
Now, the number of plants,
g(27) = 27 * 18 + 23
g(27) = 486 + 23
g(27) = 509

Thus, The required number of plants from the function is 509 when there are 27 rows.

We know that:

Mary has 5/7 of the red paint tube

And she also has 4/7 of the blue paint tube.

How much paint does she have in total?

Well, we only need to add these fractions.

5/7 + 4/7 = 9/7

We can rewrite the 9 as 7 + 2, then we get:

9/7 = (7 + 2)/7 = 7/7 + 2/7 = 1 + 2/7

This means that, in total, she has a complete tube and two sevents of other.

Answer:

x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

18x = 9 × 3 = 27 ( divide both sides by 18 )

x = [tex]\frac{27}{18}[/tex] = [tex]\frac{3}{2}[/tex]

triangle with 2 sides of equal lengths= isoceles

triangle with 3 sides of equal lengths= equilateral

Answer:

if the two sides are congruent, then it's an isosceles triangle.

all angles congruent and it's an equilateral.

all angles unequal and it's a scalene.

if all the angle measures are less than 90 degrees, then it's acute, but more than 90 degrees would be obtuse.

Answer:

y = 2(4^(x))

Step-by-step explanation:

In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions.

This means in 2012, it was 2^(5) lions while after 1 year it was 2^(7) lions

Thus, it increases every year by a ratio of 2^(2)

Thus, in 2011, it was 2^(5) - 2^(2) = 2^(3) lions

In 2010, it was 2^(3) - 2^(2) = 2

Since Lions were introduced in the park in 2010, using f(x), it means;

at x = 0, f(x) = 2

at x = 1, f(x) = 2^(3)

at x = 2, f(x) = 2^(5)

at x = 3, f(x) = 2^(7)

To find an exponential function that models the situation, let's use the generic formula: y = ab^(x)

At x = 0 and y = 2, we have;

2 = a × b^(0)

Thus,a = 2

At x = 1, y = 2^(3)

Thus; 2^(3) = 2 × b^(1)

b = 8/2

b = 4

So the exponential equation is;

y = 2(4^(x))

You can use the fact that the given figures are expressible as 2 raised to some powers.

The exponential function modeling the number of lions to the years passed since 2010 is given as

[tex]f(x) = 2^{1+2x}[/tex]

Those functions which are expressed as some constant raised to the power of the argument called exponential function.

Since 2012  - 2010 = 2 and the number of lions = 32 = [tex]2^5[/tex]

and 2013 -2010 = 3 and the number of lions =128 = [tex]2^7[/tex]

Thus, there is increment of 2 exponent as 1 year was changed.

Thus, we have:

[tex]f(x) = 2^{2x + a}[/tex] where a might be some constant( i took this form of exponent just by trial and error. It was already visible that one year was increasing double output, thus 2x and since there was just double increase and no other effect, there might be some non variable thing(a constant) so i thought to try some variable and see if this can work)

Since at x = 2, we get 2 raised to the power 5

thus.

[tex]2(2) + a = 5\\a = 1[/tex]

Thus,

The exponential function modeling the number of lions to the years passed since 2010 is given as

[tex]f(x) = 2^{1+2x}[/tex]

You can see that this will give correct output for x = 2 and x = 3

Answer:

3.66 cm

Step-by-step explanation:

r = Radius of cylinder

h = Height of the cylinder = 11 cm

A = Total surface area of the cylinder = [tex]337\ \text{cm}^2[/tex]

Total surface area of a cylinder is given by

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65[/tex]

So, the radius of the circular top is 3.66 cm.

Answer:

1582480848 miles

Step-by-step explanation:

The maximum distance is another vertex of the major axis

1,636,484,848 miles - 54,004,000 miles = 1582480848 miles

Based on the calculations, the maximum distance from the Comet to the Sun is equal to 1,582,480,848 miles.

In this scenario, the elliptical orbit of the Comet with respect to the Sun at one focus and a major axis is equal to 1,636,484,848 miles. Also, the closest it came to the Sun is 54,004,000 miles.

Thus, we would divide the length of the major axis by the distance between the Comet and the Sun as follows:

Maximum distance = 1,636,484,848/54,004,000

Maximum distance = 1,582,480,848 miles.
