Answer:
the time taken for having 1 million bacteria is 137.68 hours
Step-by-step explanation:
The computation is shown below:
y = 2 × (1.10)^x
1,000,000 = 2 × (1.10)^x
500,000 = (1.10)^x
x = log (500,000) ÷ log (1.10)
= 137.68 hours
hence the time taken for having 1 million bacteria is 137.68 hours

First of all, the circle on -3 did not have filling so that means it is not equal to z. Then we look on the circle on 6. It does have a filling which means it is equal to and greater than z. Now we look in between -3 and 6. Is there any white spots? If no, then we don’t have to use an OR. Therefore, the first answer is the only plausible answer.

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.
Answer:
Sample response: If x represents the number of downloads, you can write the inequality 1.29x ≤ 20. Solving the inequality, you find that x is less than or equal to about 15.5. Since he can’t download part of a song, Joseph can download 15 or fewer songs.

Find the perimeter and area of this shape
Answer:
Area: 38.48u² Perimeter: 24.995u
Step-by-step explanation:
This is a quarter of a circle. You can use the formula to find the area of a full circle and then divide it by 4 to find the area of a quarter circle.
The radius is 7. So..
A = πr²/4 = π × 7²/4
= π × 49/4
= 12.25π
≈ 38.48u²
You have to find the circumference of the full circle in order to find the perimeter of this shape. The circumference is πd.
To find the diameter of a circle you multiply the radius by 2.
7 × 2 = 14
P = π14
≈ 43.98
Then, you divide that number by 4 because the arc (the curved part) is a quarter of the circumference.
43. 98 ÷ 4 = 10.995 - This is the length of the arc.
Now you add all the measurements:
7 + 7 + 10.995 = 24.995u
I hope this helps! :)

if the graph of a parabola that opens upward is shifted 2 units to the right and 3 units down, how is the axis of symmetry affected
The axis of the symmetry will be shifted 2 units to the right.
What is Parabola?A parabola is a two dimensional figure on a plane which is U shaped and any point on the parabola is at an equal distance from a fixed point called focus and a fixed line called directrix.
The axis of symmetry of a parabola is the line which passes through the vertex of the parabola and divides the parabola in to two equal halves.
If the parabola is opening upward, then the axis of symmetry will be a vertical line passing through x = h, where h is the x coordinate of the vertex.
When the parabola is shifted 2 units to the right, then the x coordinate of the vertex changes to h + 2.
So the new axis of symmetry will be x = h + 2.
So the axis of symmetry is shifted 2 units to the right.
There will be no effect that the parabola moves 3 units down. The axis of symmetry will be the same.
Hence the axis of the symmetry will be shifted 2 units to the right.

kim rolls a dice and flips a coin
a) calculate the probability that she gets a 2 and a head
b) workout the probablity that she gets an even number and a tail
Since, both the events are independent.
So, P(A+B) = P(A)×P(B)
a) P( Head & Getting a 2 ) = P( head ) × P( Getting a 2 )
[tex]=\dfrac{1}{2}\times \dfrac{1}{6}\\\\=\dfrac{1}{12}[/tex]
b) P( Even number & Tail ) = P( Even number ) × P( Tail )
[tex]=\dfrac{3}{6}\times \dfrac{1}{2}\\\\= \dfrac{1}{4}[/tex]
Hence, this is the required solution.
