How do I find the indicated value for this problem?

Answer:B

Step-by-step explanation:

Answer:

It's false.

Step-by-step explanation:

By breaking the middle term.

Put the root into equation, if it equals 0, then it's a root.

2x^2+3x-1=0

2(1/2)^2+3(1/2)-1=0

2(1/4)+3/2-1=0

2/4+3/2-1=0

1/2+3/2-1=0

(1+3-1*2)/2

4-2/2 = 1

1 is not equal to 0.

Answer:

1. x = 14

2. (14, 115.18)

3. If the cost was 115.18 dollars, then the number of rooms cleaned was 14.

Step-by-step explanation:

The goal of this exercise is to teach you how to create formulas for story problems and substitute variables in equations to find solutions.

To do the first question, you simply have to make the equation from the story problem.

These equations are usually in the slope intercept form, y = mx + b

C(x) is the same as y, so begin by replacing it for simplicity.

If x represents the number of rooms cleared, that means that the cost for each room would be 7.87x. There's also a reservation fee of $5, which means your y-intercept is 5.

y = 7.87x + 5

Now we can substitute variables to solve the equation.

To find x when C(x) = 115.18, we substitute y for 115.18.

115.18 = 7.87x + 5

Subtract 5 from both sides:

110.18 = 7.87x

Divide both sides by 7.87:

14 = x

So we have our first answer. When C(x) = 115.18, x = 14.

The second answer can be easily completed. Ordered pairs are written as (x,y), so we substitute the variables for their values.

This means, as an ordered pair, the answer is (14,115.18).

The sentence would be "If the cost was 115.18 dollars, then the number of rooms cleaned was 14.

Answer:

72in^2

Step-by-step explanation:

Area of triangle:

base*height/2

Area = 16*9/2

Area = 72in^2

Answer:

13

Step-by-step explanation:

Just In case you want explanation-

1. 4 squared Meaning 4 x 4 = 16

2. 16 x 6 = 96

3x 6 = 18

96- 18 = 78

in the denominator, 25/ 5 = 5

11 minus 5 = 6

78 divided by 6

it gives you 13

Answer:

f(x)= 10,000(2)^x

Step-by-step explanation:

Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.

A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]

An exponential growth function is a function that grows at a constant percent growth rate.

f(t) = a×(1 + r)^(t)

where f(t) = exponential growth function

a = initial amount

r = growth rate

t = number of time intervals

For given example,

initially a bacteria population (a) = 10,000

Five days later, they find that the population has doubled.

d = 5, f(5) = 20,000

Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.

[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]

This means, the exponential growth function would be,

[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.

Answer:

15/3 =5 is the correct answer

Answer:

1.46 cm

Step-by-step explanation:

You have to first convert meters into centimeters to make everything easier. (1m = 100cm)

1.52 meters is 152 centimeters

152-6 = 146 cm

146 cm divided by 100 is 1.46 meters

Answer:

268°

Step-by-step explanation:

Answer:

B and D both lead to failure. I have no idea how to pick which one is right. I guess D but don't be surprised if it is B. The question tries to do too much.

D

Step-by-step explanation:

No.

You need one more fact.

You can't pick A. Angles are not noted.

B: there is no mention of parallel sides. This is why the proposition fails to give a parallelogram.

C: you haven't got both sides being parallel. You haven't even got one set of opposite sides being parallel

D: This is probably another alternative. You don't know anything about 1 set of opposite sides.

E: No angles are marked.
