A scientist is studying bacteria in a dish and discovered they grow and can 3 be tracked using the formula: 5*(1.50)^x +10, where x represents every hour. How many bacteria will there be after 9 hours? (Round Your Answer To The Nearest Whole Number)
A) 38
B) 48
C) 192
D) 202
Answers
Answer:
D
Step-by-step explanation:
if x= number of hours replace the x by 9
so you have 5×(1.50)^9+10=
5×(192.21)+10 = 202.21 so 202 will be nearest whole number
Steps:
Formula 5*(1.50)^x + 10
1. Plug in 9 for x
5*(1.50)^9 +10
2. Solve exponents (38.443359375) and round to nearest hundredth
5*38.44+10
3. Multiply

Distribute (2m-5m)(-5)
Answers
First Method (Distributive Property)
(2m - 5m) (-5)
Rearrange the equation to make it easier.
(-5) (2m - 5m)
In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).
-10m + 25m
15m
Second Method
(2m - 5m) (-5)
Since 2m and 5m have the same variable, we can subtract them.
(-3m) (-5)
Multiply.
15m
15m is your answer. I hope this helps!

Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left
Answer:area of 4 equal circle having
Diameter =2ft
Therefore radius =r=2/2=1ft
Area of 4 equal circle =4(πr²) =4π×1²=4πft²
Area of square=length²=4²=16
Area of shaded region =area of square-
area of 4 equal circle
=16-4π=3.43362938564ft²

What is the equation in slope intercept form of the line that has a slope of 0.25 and passes through the point (6, - 8)
Answers
Answer:
y = 0.25x - 9.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 0.25 , then
y = 0.25x + c ← is the partial equation
To find c substitute (6, - 8) into the partial equation
- 8 = 1.5 + c ⇒ c = - 8 - 1.5 = - 9.5
y = 0.25x - 9.5 ← equation of line
Answer:
y = 0.25x - 9.5Step-by-step explanation:
The equation in point-slope form:
y = 0.25(x - 6) - 8
y = 0.25x - 1.5 - 8
y = 0.25x - 9.5 ← slope-intercept form

find NM
Answers
Answer:
NM = 15
Step-by-step explanation:
Given a secant and a tangent from an external point to the circle, then
The square of the measure of the tangent is equal to the product of the secant's external part and the entire secant, that is
(x + 3)² = (x - 3)(x - 3 + 16)
(x + 3)² = (x - 3)(x + 13) ← expand both sides using FOIL
x² + 6x + 9 = x² + 10x - 39 ( subtract x² + 10x from both sides )
- 4x + 9 = - 39 ( subtract 9 from both sides )
- 4x = - 48 ( divide both sides by - 4 )
x = 12
Then
NM = x + 3 = 12 + 3 = 15

= 6(2/3)²
= 6(2/3)(2/3) one of the 3s divide into 6 twice

A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answers
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

Directions: For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v= √ar, where a is the car’s acceleration in m/s2.
1. For safety reasons, a ride has a minimum acceleration of 39.2 m/s2. If the cars on the ride have a velocity of 14 m/s what is the smallest radius that any curve on the ride may have?
2. What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?
Answers
Answer:
1. r = 5 m 2. a = 25.6 m/s²
Step-by-step explanation:
The relation between the velocity, the radius of path and the acceleration on the circular path is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
1. Acceleration, a = 39.2 m/s²
Velocity of the car, v = 14 m/s
The radius of the path can be calculated using the above formula i.e.
[tex]r=\dfrac{v^2}{a}\\\\r=\dfrac{(14)^2}{39.2}\\\\r=5\ m[/tex]
2. Velocity of the car, v = 8 m/s
The radius of the path, r = 2.5 m
The acceleration of the car is given by :
[tex]a=\dfrac{8^2}{2.5}\\\\a=25.6\ m/s^2[/tex]
Hence, this is the required solution.
