Answer:

18 Liters of water

Answer:

Part 1: plant f

Part 2: plant g

Part 3: plant g

Step-by-step explanation:

✔️First plant:

Function: f(t) = 0.5t + 2

where,

f(t) = height of plant

t = number of days

m = slope/rate of change = 0.5 cm/day

b = y-intercept/initial height = 2 cm

✔️Second Plant: using two points on the graph, (0, 5) and (16, 9), let's find b and m for the function of the second plant.

Slope/rate of change (m) = ∆y/∆x = (9 - 5)/(16 - 0) = 4/16 = 0.25

m = 0.25 cm/day

The y-intercept or initial height is the y-coordinate of the point where the line intercepts the y-axis = 5

b = 5 cm

Towbrute the equation of the function, substitute m = 0.25 and b = 5 into g(t) = mt + b

Thus:

g(t) = 0.25t + 5

Knowing these, let's answer the problem given:

Part 1: plant f was growing faster because it has a greater rate of change/slope (m) of 0.5 cm/day

Part 2: plant g was taller because it has a greater initial value/y-intercept (b) which is 5 cm

Part 3: To find out which plant was taller after 8 days, substitute t = 8 into the equation of each function:

Plant f: f(t) = 0.5t + 2

f(8) = 0.5*8 + 2 = 4 + 2

f(8) = 6 cm

Plant g: f(t) = 0.25t + 5

g(8) = 0.25*8 + 5 = 2 + 5

g(8) = 7 cm

Thus, plant g was taller after 8 days having 7 cm

let one angle be X

so, other angle be 5x-12

ATQ

X+5x-12=180

6x=180-12

6x=168

X=168/6

hence X=28

now,one angle=28

other angle is 5×28-12

= 140-12.

= 128

Answer:

x =  -14.75

Step-by-step explanation:

-4(5+x)=39         (Distribute)

-20 - 4x = 39          (Add 20 on both sides)

-4x = 39 + 20

-4x = 59             (Divide by -4)

x = -14.75

Answer:

First think of what you are trying to solve.

What is X?

Reverse the steps in solving:

[tex]39 / -4 = -9.75[/tex]

Now after doing that, subtract it by 5:

[tex]-9.75 - 5 = -14.75[/tex]

Now after doing that, to check your work:

[tex]-14.75 + 5 = -9.75 * -4 = 39[/tex]

So the answer for X is -14.75

There you go I hoped I helped :]

Answer:  no solution

Step-by-step explanation:

here are the equations in y=mx+b form:

y=2x+1

y=2x+ -5/2

as you can see they have the same slope with different y-intercepts, this mean there are parallel AKA no solution

Answer:

8

Step-by-step explanation:

Answer:

(1,0)

Step-by-step explanation:

Given

[tex]H = (-2,2)[/tex]

[tex]I = (4,3)[/tex]

[tex]J = (4,-2)[/tex]

[tex]K = (-2,-3)[/tex]

Required

The midpoint of the diagonals

Midpoint is calculated as:

[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

For H and J, the midpoint is:

[tex]M = (\frac{-2+4}{2},\frac{2-2}{2})[/tex]

[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]

[tex]M = (1,0)[/tex]

For I and K, the midpoint is:

[tex]M = (\frac{4 - 2}{2},\frac{3-3}{2})[/tex]

[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]

[tex]M = (1,0)[/tex]

The midpoint of both diagonal is: (1,0)

Answer:

Step-by-step explanation:

1. Angles P₂ and N₁ are opposite angles of inscribed quadrilateral PMNQ, so are supplementary. Angles N₁ and N₂ form a linear pair, so are supplementary. Angles supplementary to the same angle (N₁) are congruent, hence P₂ = x ≅ N₂

__

2. ΔPMQ is isosceles, so angle Q₁ is also congruent to x.

__

3. In ΔPMQ, the sum of angles is 180°, so ...

  M₁ +2x = 180°

Dividing by 2 gives ...

  M₁/2 +x = 90°

Angle M₁ subtends arc PQ of circle M. Angle R inscribed in circle M subtends the same arc, so ...

  R = (M₁/2)

  R = 90° -x

__

4. From the above, we know that angles N₂ and R are complementary (total 90°), so angle S₂ = 90°. Segment MS will only intersect chord PR at right angles at the midpoint of that chord.

Hence S is the midpoint of PR and PS = SR.

Answer:

  not on the same line

Step-by-step explanation:

Any two distinct points define a line. Additional points may or may not be on that line. If they are on the line, they are collinear with other points on the same line.

Any point not on the line is noncollinear with the points that are on the line.

Answer:

The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27:1

Step By Step Explanation:

Volume of the smaller cylinder(V1)=π(r^2)h

Volume of the larger cylinder(V2)=π(r^2)h

=π(3r)^2*3h

=π*9(r^2)*3h

=27π(r^2)h

The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27π(r^2)h/π(r^2)h i.e. 27:1

Answer:

z = -11, z = -2

Step-by-step explanation:

Given that, ([tex]f(z)=\sqrt{z+27} -z[/tex]) and ([tex]f(z)=7[/tex]), set up an equation that puts the first value of ([tex]f(z)[/tex]) equal to the other given value of the function.

[tex]f(z)=\sqrt{z+27}-z=7[/tex]

Use inverse operations to solve,

[tex]\sqrt{z+27}-z=7\\\\\sqrt{z-27}=7+z\\\\z+27 = (7+z)^2\\\\z + 27 = 49+14z+z^2\\ -(27+z)\\\\0 = z^2+13z+22[/tex]

Factor,

[tex]0=(z+11)(z+2)[/tex]

Solve using the zero product property, the zero product property states that any number times zero equals zero;

[tex]z=-11,z=-2[/tex]
