Answer:

See the screenshot! :)

Step-by-step explanation:

we have a exponential function of the form

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

where

y ---> is the population of bacteria

x ---> the number of hours

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

a=700 bacteria

r=5%=5/100=0.05

so

b=1+0.05=1.05

substitute

y=700([tex]1.05^x[/tex])

For x=20 hours

substitute in the equation and solve for y

y=700(1.05)^20= 1,857 bacteria

Hope this helped! :)

Answer:

5

Step-by-step explanation:

The answer is 5

Answer:

Step-by-step explanation:

Ok, so we have the equations:

7x-2y=-13

and

2y-5x=11

So first things first, we can cancel out 2y from both equations because they are common factors.

So we are left with the equations:

7x=-13

and

5x=11

So we add the two common factors and get:

12x=-24

And now we divide on both sides and get:

x=-2

Answer: D. ∠HKG ≅ ∠LGK

Step-by-step explanation:

Given: Quadrilateral GHKL where diagonal GK is drawn such that it forms two triangles GHK and KLG.

Side GL  ≅  Side KH

Now, GK is common in both triangles GHK and KLG.

and GK ≅GK

SAS congruence rule: If any two sides and the angle included between the sides of one triangle are congruent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent.

So ∠HKG must be congruent to ∠LGK ( angles between the congruent sides).

Hence, the correct option is D. ∠HKG ≅ ∠LGK

Question:

What other information do you need to prove ∆ GHK ≅ ∆ KLG by SAS?

Answer:

HKG ≅ LGK

Step-by-step explanation:

Answer:

Angle 2 = 45 degrees

Step-by-step explanation:

Angle 1 = Angle D because they are alternate interior angles.

Angle 3 = Angle A because they are alternate exterior angles.

Angle 1 = 135 degrees

Therefore, Angle D = 135 degrees

180 - Angle D = Angle 2

Angle 2 = 180 - 135

Angle 2 = 45 degrees

Answer:

Equation of a straight line is given as y = mx+c

m = slope or gradient or dy/dx or y2 - y1/ x2 - x1

c = intercept

y = 2x - 7

y = -x + 1

y = 2x - 10

Step-by-step explanation:

Using y = mx+c

A. m=2 y=-7 x=0

-7= 2*0 + c

-7=c

y = 2*x - 7

y = 2x - 7

B. x1=3 x2=-2 y1=-4 y2=1

m = y2 - y1/ x2 - x1

m = 1+4 / -2-3

m = 5/-5 which is equal to -1

using any value for y and x, let's use x1 and y1

-2 = -1*3 + c

-2 = -3 + c

1 = c

y = -1*x + 1

y = -x + 1

C. x1=6 x2= 5 y1= 2 y2=0

m = y2 - y1/ x2 - x1

m = 0-2 / 5-6

m = -2/-1 which is equal to 2

using any value for y and x, let's use x1and y1

2 = 2*6 + c

2 = 12 + c

-10 = c

y = 2*x -10

y = 2x - 10

Answer:

[tex] {64m}^{9} {n}^{3} [/tex]

Step-by-step explanation:

Forst thing to do in this is to write it out, it makes more sense of the problem.

[tex]( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } ) \times ( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } ) \times( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } )[/tex]

Now we can solve for the equation, it takes time.

Step-by-step explanation:

Answer:

4.8 hours

Step-by-step explanation:

The formula for half life is given as:

t½ = t × In(2)/In(No/Nt)

Where

t½ = Half life

t = time in hours = 4

No = Initial amount = 10mg

Nt = Final amount after 3 hours = 6.5 mg

t½ = 3 × In(2) /In(10/6.5)

t½ = 4.8271216522281 hours

Approximately = 4.8 hours

The half-life of the medication, in hours, is 4.8 hours.

Given that,

Based on the above information, the calculation is as follows:

The following formula should be used:

[tex]= t \times ln(2)\div ln(No\div Nt)[/tex]

 Here

t denotes the time in hours i.e. 4

No means the Initial amount i.e. 10mg

Nt means Final amount after 3 hours i.e. 6.5 mg

So,

[tex]= 3 \times ln(2) \div ln(10\div 6.5)[/tex]

= 4.82

 = 4.8 hours

Therefore we can conclude that the half-life of the medication, in hours, is 4.8 hours.

Answer:

10 and -10

Step-by-step explanation:

Absolute value is the distance of a number from 0. Absolute value must be positive because you can not a have a negative distance from 0. The two numbers that have a distance of 10 from 0 on the number line are 10 and -10.

Answer:

The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.

Step-by-step explanation:

Answer:

the fourth month

Step-by-step explanation:

200 + 50m = 100 + 75m

subtract 100 on both sides

100 + 50m = 75m

subtract 50m on both sides

100 = 25m

divide by 25 on both sides

m = 4

Answer:

See below for answers

Step-by-step explanation:

1st Problem:

Because the figure is a triangle, it's interior angles will add up to 180 always. Since it's a right triangle, we know one of the angles is 90, but we'll need to set up an equation to solve for x.

90+(2x-2)+(x+5)=180

2x-2+x+5=90

3x+3=90

3x=87

x=29

Therefore, B) 29, is the correct answer

2nd Problem:

Given side lengths of a, b, and c, if a+b<c, then it's a triangle. Since 8+8 is not less than 16, the sides do not make a triangle. The hypotenuse, c, must always be the longest length.

Therefore, A) Not a triangle, is the correct answer

3rd Problem:

To find angle x, we need the last interior angle of the triangle. Since the interior angles of a triangle add up to 180, we once again set up an equation to find the missing interior angle:

21+34+y=180

55+y=180

y=125

Since the missing interior angle is 125 degrees, it is supplementary to angle x, where supplementary angles add up to 180 degrees as well. So we would subtract 125 from 180 to get x. 180-125=55, so angle x is 55 degrees. Therefore, C) 55, is the correct answer.

4th Problem:

Again, use the Interior Angle Theorem to get x:

58+47+x=180

105+x=180

x=75

Therefore, A) 75, is the correct answer

5th Problem:

3,4,5 is a Pythagorean Triple, so it is a right triangle as 3^2+4^2=5^2. It is also scalene because none of the sides are equal to each other.

Therefore, B) Yes, scalene, is the correct answer

Answer:

  C)  14 cm

Step-by-step explanation:

A triangle solver can quickly show you the third side is 14 cm.

__

The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...

  c² = a² +b² -2ab·cos(C)

  c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74

  c ≈ √196.74 ≈ 14.03

The length of the third side is about 14 cm.

x is 280........................

It been a while since I've done these, so hopefully it's correct :)

Answer:

I don't know, the way it is typed confuses me. Is it 7/11 TIMES p-10 or is p-10 with the 11 as the denominator?  but I do hope this helps:

Step-by-step explanation:

So first I subtracted 7/11 from each side:

f(p)-7/11=(7/11-7/11)p-10

Now we are left with f(4/11p)=p-10

Now to get the variable "p" on one side, I subtracted 4/11p from both sides:

f(4/11p-4/11p)=(p-4/11p)-10

Now we are left with f=7/11p-10

Now we want the "p" to be 1p so we multiply each side by the reciprocal of 7/11:

f(11/7)=(7/11*11/7)p-10

Now we have 1 4/7f=p-10

Now we subtract 4/7 from each side and get:

f=p-9 3/7

And that's as far as I could simplify it, sorry if it's wrong... lol

The required value of f (77) is 39 for the given equation. The correct answer would be an option (B).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

f (p) = (7/11) p - 10

We have to determine the value of f (77) for the given equation.

As per the question, we have

f (p) = (7/11) p - 10

Substitute the value of p = 77 in the above equation,

f (77) = (7/11)(77) - 10

f (77) = 7 x 7 - 10

f (77) = 49 - 10

Apply the subtraction operation, and we get

f (77) = 39

Thus, the value of f (77) is 39.

Answer:

25x = 75 (Because they are alternate interior angles)

=> x = 75/25

=> x = 3

So, x = 3

Because 25x is equal to 75, the two lines (u and v) are parallel

x = 3

180-75 = 105

180-105 = 75

75/25 = 3
