Answer:
x is 4.30 and 0.697
Step-by-step explanation:
Quadratic formular:
[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ [/tex]
a » 1
b » -5
c » 3
[tex]x = \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2} - (4 \times 1 \times 3)} }{(2 \times 1)} \\ \\ x = \frac{5± \sqrt{13} }{2} [/tex]
Therefore, values of x :
[tex]x = \frac{5 + \sqrt{13} }{2} \: \: and \: \: \frac{5 - \sqrt{13} }{2} \\ \\ x = 4.30 \: \: and \: \: 0.697[/tex]

The speed of light in a vacuum is 2.998×108 m/s .
What is its speed in miles per minute (mi/min)?
To convert m/s to mi/min we have to find conversion factor first
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let’s put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min
Answer: V = 1.118 ∙ 107 mi/min
Hope u have a good day of learning
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let's put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min
Answer: V = 1.118 - 107 mi/min
The product of 6 and 14 more than a number
Answer:
its one i think
Answer:
Here, more than indicates adding, and products means result of multiplication
Thus,
6* 14+x
NOTE: These questions are to be made into an equation with using a variable. That is what i have done but if the questions states something abt the final result we get then we need to solve for x
One angle of a triangle measures 128º. The other two angles are congruent.
Enter and solve an equation to find the measurex of the congruent angles.
An equation is____
= 180.
The congruent angles each measure_____
o.
Answer:
26
Step-by-step explanation:
a triangle messures 180
you already have one angleso allyou do is subtract
180-128= 52
the since you are missing two angles all you do is divide that by 2
52/2=26

What is Q1 for this data set?
{2, 3, 5, 5, 6, 8, 8, 9, 10, 11, 11, 11, 12}
Answer:
Q1 = 5
Step-by-step explanation:
Q1 is the first quartile
Divide the data in half, that will get you Q2 or the second quartile
There are 13 data points so the middle is the 7th data point
2, 3, 5, 5, 6, 8, 8, 9, 10, 11, 11, 11, 12
Take the lower half of the data and divide it in half
There are 6 data points so the middle is between the 3rd and the 4th data point so we average them
2, 3, 5, 5, 6, 8,
(5+5)/2 = 10/2 = 5
The 1st quartile or Q1 = 5

The high temperature one day was -1 °F. The low temperature was -5 °F. What was the difference between the high and low temperatures for the day? and why
Answer:
The difference is 4 degrees
Step-by-step explanation:
If its difficult for you to subtract negatives just switch them to a positive 1 and 5 now subtract 1 from 5=4 and because the measure being used is degrees the final answer would be 4 degrees.

the number of gallons of bottled water N consumed by a person in one year is approximated by N=0.733t + 8.398, where t is the number of years since 1971. Predict the number of gallons consumed by a person in 1985.
Step-by-step explanation:
N = 0.733t + 8.398
N = 0.733(1971) + 8.398
N = 1,453.141
Step-by-step explanation:
Solution,
According to question,
N=0.733t + 8.398
When t= 1971, then
N=0.733×(1971) + 8.398
N=1453.141

1. if f(x)=3x-1, find f(-5)
2. if h(x)=2x+3 and g(x)=3-4x, find 3h(1)-g(2)
Answer:
1 f(-5) = 3(-5)-1= – 15 – 1 = – 16
2. h(1) = 2(1)+3=2+3=5
g(2)= 3- 4(2)=3 – 8 = – 5
3h(1) ‐ g(2) = 3 (5) – (-5) = 15 +5= 20
I hope I helped you^_^
Answer:
number 1 =
Let y=f(x)=3x−5
Clearly f(x) is one-one onto function so it is invertible.
y=3x−5 ⇒x = y+5/3
∴f −1 (x)= y+5/3

When a measurement in inches is converted to centimeters, will the number of centimeters be grater or less than the number of inches? Explain.
Answer:
A centimeter is smaller than an inch, so a given length will have more centimeters than inches. This alone shows you that the NUMBER of cm units will always be greater than the number of inches, for a given measurement.

brainiest to whoever right
Step-by-step explanation:
Since the the two angles are complementary, then
[tex](3x + 2) + (5x - 14) = 90[/tex]
or
[tex]8x - 12 = 90 \Rightarrow 8x = 102[/tex]
[tex]x = 12.75[/tex]
so
[tex]\angle{YXZ} = 5(12.75) - 14 = 49.75°[/tex]
