Answer:

Number of algae in 7 days = 70.355

Step-by-step explanation:

Given:

Algae in beginning = 50

Rate of increasing = 5% per day = 0.05

Number of days = 7 days

Find:

Number of algae in 7 days.

Computation:

[tex]Number\ of\ algae\ in\ 7\ days = Algae\ in\ beginning(1+Rate\ of\ increasing)^{Number\ of\ days}\\\\Number\ of\ algae\ in\ 7\ days = 50(1+0.05)^7\\\\Number\ of\ algae\ in\ 7\ days = 70.355[/tex]

Answer:

  A.  B = 64.13° or B' = 115.87°

Step-by-step explanation:

The given angle is opposite the shortest of the given sides, so there are two possible solutions using the Law of Sines. Either way, we have ...

  sin(B)/16 = sin(θ)/15.4

  B = arcsin(16/15.4·sin(60°)) ≈ arcsin(0.899767)

  B = 64.13° or B' = 180° -64.13° = 115.87°

Step-by-step explanation:

The first number is -2 and the second number is 1

Answer:

The first number is -2 and the second number is 1.

Step-by-step explanation:

2n + 3s = -1

(n + 4s = 2)-2             Multiply by -2 to cancel the n

2n + 3s = -1

-2n - 8s = -4               Add these equations together

-5s = -5                      Divide both sides by -5

s = 1

Plug this into the first equation to find the value of n

2n + 3(1) = -1              Multiply

2n + 3 = -1

     - 3    - 3                Subtract 3 from both sides

2n = -4                       Divide both sides by 2

n = -2

(–1, –6)

Step-by-step explanation:

Given that S(3, –5) was translated to S'(–4, 1), the transformation rule is (x-7, y+6). Then, the coordinates of square RSTU are:

R'(–8, 1) -> (-8+7, 1-6) -> R(-1, -5)

S'(–4, 1) -> (-4+7, 1-6) -> S(3, -5)

T'(–4, –3) -> (-4+7, -3-6) -> T(3, -9)

U'(–8, –3) -> (-8+7, -3-6) -> U(-1, -9)

The point (–1, –6) lies on the segment RU

The point that lies on a side of the pre-image is mathematically given as

x=(-1,-6)

A pre-image is simply a the group of chosen elements from a mapped domain to give a given subset of the codomain.

Question Parameter(s):

which has vertices

R'(–8, 1),

S'(–4, 1),

T'(–4, –3),

U'(–8,

Generally, the equation for the transformation  is mathematically given as

(x-7, y+6).

Therefore

R'(–8, 1) --> (-8+7, 1-6)

R'(–8, 1) --> R(-1, -5)

S'(–4, 1) -=> (-4+7, 1-6)

S'(–4, 1)-> S(3, -5)

T'(–4, –3) --> (-4+7, -3-6)

T'(–4, –3 -> T(3, -9)

U'(–8, –3) --> (-8+7, -3-6)

U'(–8, –3)-> U(-1, -9)

In conclusion, point S with coordinates of (3, –5) lies within RU

Answer:

Step-by-step explanation:

Solve the given 3x + 5y = 2 for y.  This will automatically indicate the slope of the line.

Subtracting 3x from both sides of this equation, we get:

5y = -3x = -3x + 2.

Dividing both sides by 5 yields y = (-3/5)x + 2/5.

The slope of the given line is -3/5.  The y-intercept of this line is (0, 2/5).

Answer:

Percent error is [tex]7.4\%[/tex]

Step-by-step explanation:

Given:

As per the result of experimental work, density of a liquid is 0.1369 g/㎤

Known density of the liquid is 0.1478 g/㎤

To find: percent error

Solution:

The density of a substance is defined as mass per unit volume.

S.I. unit is Kilogram per cubic metre.

Error = Actual density - density as per the experiment = [tex]0.1478-0.1369=1.0109\,\,g/cm^3[/tex]

Percent error = ( error/Actual error ) × 100 = [tex]\frac{0.0109}{0.1478}\times 100=7.4\%[/tex]

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

A. We can calculate the slope using (y2 - y1) / (x2 - x1)

= (3 - (-2)) / (1 - 6)

=  5/-5

= -1.

So the given slope of 3 or one of the points is NOT correct.

B. If the point (1, 3 ) and the slope are correct then the equation  for the line  (using the point-slope form) is y - 3 = 3(x - 1)  

C Another point on this line would be , when x = 0 , y = 3*-1 + 3 = 0

so it's (0, 0)

D. If the given points are correct the slope is ( as above) =  -1.

E. The equation for this line is

y - 3 = -1(x - 1)

y = -x + 1 + 3

y = 4 - x.

Answer:

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

Step-by-step explanation:

Given

Points (-2,0) and (-3,-1)

Required

Equation of Line

The first step is to determine the slope of the line; using the following formula

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]Where\ (x_1,y_1) = (-2,0)\ and\ (x_2,y_2) = (-3,-1)[/tex]

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes

[tex]m = \frac{-1 -0}{-3 - (-2)}[/tex]

[tex]m = \frac{-1}{-3 +2}[/tex]

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

[tex]m = 1[/tex]

The next is to determine the equation of the line using any of the points

The formula is as thus;

[tex]m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}[/tex]

Using [tex]m = \frac{y - y_1}{x - x_1}[/tex]

[tex]Where\ (x_1,y_1) = (-2,0)\ and\ m =1[/tex]

[tex]1 = \frac{y-0}{x - (-2)}[/tex]

[tex]1 = \frac{y-0}{x +2}[/tex]

[tex]1 = \frac{y}{x +2}[/tex]

Multiply both sides by x + 2

[tex](x+2)*1 = \frac{y}{x +2} * (x+2)[/tex]

[tex](x+2)*1 = y[/tex]

[tex]x+2 = y[/tex]

[tex]y = x + 2[/tex]

Subtract x from both sides

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

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

Hence, the equation of the line in standard form is [tex]y - x = 2[/tex]

Answer:

the parabola can be written as:

f(x) = y = a*x^2 + b*x + c

first step.

find the vertex at:

x  = -b/2a

the vertex will be the point (-b/2a, f(-b/2a))

now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.

The next step is to see if we have real roots by using the Bhaskara's equation:

[tex]x = \frac{-b +-\sqrt{b^2 -4ac} }{2a}[/tex]

Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.

If you do not have any real roots, you can feed into the parabola some different values of x around the vertex

for example at:

x =  (-b/2a) + 1 and x =  (-b/2a) - 1

those two values should give the same value of y, and now you can connect the vertex with those two points.

If you want a more exact drawing, you can add more points (like x =  (-b/2a) + 3 and x =  (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.
