Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.
The answer is 11.0 or just 11.
Ed: Explanation below.
11.00
10.99
10.98
10.97
10.96
10.95 Look at the 9. Then look to the right. Do I round up or down?
10.94
10.93
10.92
10.91
10.90
If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.
Therefore, the answer is 11.

Dana said that speed, s, could be either an independent or dependent variable. Write a situation where speed, s, is an independent variable. Then write a situation where speed, s, is a dependent variable.
Answers
Answer:
As dependent variable;
speed = distance/time
As independent variable
distance = speed * time
Stepbystep explanation:
When we say dependent variable, we mean that the value of the speed depends on some values.
When we say independent, we mean the value of some quantities is dependent on the speed.
As dependent variable;
speed = distance/time
As independent variable
distance = speed * time
Answer:
Part 1: C. Speed, s, could be an independent variable affecting the time it takes to walk a certain distance.
Part 2: A. Speed, s, could be a dependent variable based on how fast your legs move.

A social media website had 100,000 followers its first year. The number of followers increased by 9% each year. Write an exponential growth function to represent this situation
Answers
Answer:
an exponential growth function to represent this situation is:
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]
Stepbystep explanation:
We know that the exponential growth function is of the form
[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]
where
x(t) represents the value at time tx₀ represents the initial value at time t = 0. In other words, it is the initial value (the amount before measuring growth or decay)r represents the growth factor when r > 0 and decay factor when r < 0t represents the of time intervals that have passed
In our case,
Given that
A social media website had 100,000 followers its first year. Thus,
x₀ = 100,000
The number of followers increased by 9% each year. Thus,
r = 9% = 0.09
Thus, substituting r = 0.09 and x₀ = 100,000 in the growth function
[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]
[tex]x\left(t\right)=100,000\times \left(1+0.09\right)^t\:[/tex]
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]
Therefore, an exponential growth function to represent this situation is:
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]

A shelf has the shape of a triangle. The base of the shelf is 36 centimeters, and the height is 18 centimeters. Find the area of the shelf in square inches. Round to the nearest hundredth.
Answers
Answer:
50.22 in²
Stepbystep explanation:
A shelf has the shape of a triangle. The base of the shelf is 36 centimeters, and the height is 18 centimeters. Find the area of the shelf in square inches. Round to the nearest hundredth.
Area of a Triangle = 1/2 × Base × Height
Base = 36 cm
Height = 18 cm
Area of the Triangle = 1/2 × 36 × 18
= 324 cm²
The area of the shelf(Triangular in shape) = 324 cm²
Converting to square inches
1 square centimetre = 0.155 square inch
324 square centimetre = x
x = 324 × 0.155 in²
x = 50.2201 in²
Approximately to the nearest hundredth = 50.22 in²
Therefore, the area of the shelf in square inches is 50.22 in²

Translate circle A using the rule (x + 4, y + 3).
Rotate circle A 45° about the center.
Dilate circle A by a scale factor of 4.
Reflect circle A about the origin.
Answers
Answer:
c took quiz
Stepbystep explanation:
Circle A can be made similar to circle B by dilating circle A by scale factor 4.
Circles can be made similar by performing transformations such as dilations, translation, etc.
The given parameters are:
Circle A
[tex](x,y) = (6,7)[/tex]  center
[tex]r=4[/tex]  radius
Circle B
[tex](x,y) = (2,4)[/tex]  center
[tex]r = 16[/tex]  radius
To do this, we simply make both circles have the same radius.
Given that:
[tex]r_A=4[/tex]  radius of A
[tex]r_B = 16[/tex]  radius of B
Dilating the radius of A by 4 will make both circles have the same radius.
i.e.
[tex]R = r_A * 4[/tex]
[tex]R = 4 * 4[/tex]
[tex]R = 16[/tex]
Now, the new radius of A is 16; same as B
Both circles now have the same radius, means that the circles are similar.

Find three consecutive even integers such that six times the sum of the first and the third is twenty  four greater than eleven times the second .
Answers
Answer:
1st = 22
2nd = 24
3rd = 26
Stepbystep explanation:
1st = x
2nd = x +2
3rd = x + 4
6(x + x + 4) = 24 + 11(x + 2)
6(2x + 4) = 24 + 11x + 22
12x + 24 = 46 + 11x
x + 24 = 46
x = 22
x + 2 = 24
x + 4 = 26
The three consecutive even numbers are 22, 24 and 26
An even number is a number that can be divided by 2 and there would be no remainder. Examples of even numbers are 2, 4, 6, 8, 10
Let:
x represent the first even number
(x +2) represent the second even number
(x +4) represent the third even number
The equation that represents the verbal explanation in the question is:
6[ x + (x +4)] = 24 + 11(x + 2)
6(2x +4) = 24 + 11x + 22
12x + 24 = 46 + 11x
Combine similar terms
12x  11x = 46  24
x = 22
(x + 2)= 22 + 2 = 24
(x + 4) = 22 + 4 = 26

What are all the values of x for which the function f defined by f(x) = (x^2  3)e^xis increasing?
(A) There are no such values of x
(B) x < 1 and x > 3
(D) 1 < x <3
(C) 3 < x < 1
Answers
I’m pretty sure it’s D
Function f(x) is increasing for values of [tex]x<1[/tex] and [tex]x>3[/tex] .
Therefore, option (B) is correct.
Given function is,
[tex]f(x)=(x^{2} 3)e^{x}\\\\f(x)=x^{2} e^{x}3e^{x}[/tex]
Taking first derivative of above function.
[tex]f'(x)=2xe^{x} e^{x} x^{2} +3e^{x} \\\\f'(x)=e^{x}(2xx^{2} +3) \\\\f'(x)=e^{x}(x+1)(x3)[/tex]
To find critical points, equate above derivative to zero.
We get, x = 1 , x = 3
We have three interval, (∞ , 1) , (1, 3) and (3, ∞)
Since, in interval (∞ , 1) and (3, ∞) function f(x) is positive.
Therefore, In interval (∞ , 1) and (3, ∞) function is increasing.
Thus, option B is correct.
