Answer:
c = 4
Step-by-step explanation:
[tex]2(c + 1) = 10[/tex]
[tex] \mapsto2c + 2 = 10[/tex]
[tex] \mapsto2c = 10 - 2[/tex]
[tex] \mapsto2c = 8[/tex]
[tex] \mapsto \: c = 8 \div 2[/tex]
[tex] \therefore \: c = 4[/tex]
are 16/72 and 18/81 equivalent rational numbers
Answer:
yes
Step-by-step explanation:
[tex]\frac{16}{72}[/tex] ( divide numerator/ denominator by 8, the LCM of 16 and 72 )
= [tex]\frac{2}{9}[/tex]
[tex]\frac{18}{81}[/tex] (divide numerator/ denominator by 9 the LCM of 18 and 81 )
= [tex]\frac{2}{9}[/tex]
Both rational numbers simplify to [tex]\frac{2}{9}[/tex] and are equivalent

What is the domain of F
Answer:
-5 ≤x≤6
[-5,6]
Step-by-step explanation:
The domain is the values that the input takes
x goes from -5 (inclusive) to 6 (inclusive)
-5 ≤x≤6
[-5,6]
Answer:
[-5, 6]
Step-by-step explanation:
The domain of a function is the list of x values. Since the endpoints are shaded, that means those x values are included as well. Therefore, the domain of f is [-5, 6].
solutions: ( x = 2 & x = -2 )

If K = F( A + B ) , find “ A ” if F = 2 , B = 3 , K = 10
Answer:
The value of A is 2
Step-by-step explanation:
F = 2 , B = 3 , K = 10
K = F( A + B )
10 = 2(A + 3)
10 = 2A + 6
Now, Subtract 6 from each side we get,
10 - 6 = 2A + 6 - 6
4 = 2A
2A = 4
Now, divide both side by 2 we get,
2A/2 = 4/2
A = 2
Thus, The value of A is 2
FOR VERIFICATION ONLY :-K = F( A + B )
10 = 2(2 + 3)
10 = 2(5)
10 = 10

write y+7 = 2/3 (4x-6) in standard form using integers
9514 1404 393
Answer:
8x -3y = 33
Step-by-step explanation:
Multiply by 3 to eliminate the fraction. Then rearrange to standard form.
y +7 = 2/3(4x -6) . . . . . . . given
3(y +7) = 2(4x -6) . . . . . . . multiply by 3
3y +21 = 8x -12 . . . . . . . . eliminate parentheses
33 = 8x -3y . . . . . . . . . . add 12-3y to both sides
8x -3y = 33 . . . . . . . . . swap sides to put into standard form
_____
Standard form has mutually prime integer coefficients, the leading one being positive.

Find the slope of a line parallel to the line whose equation is y-4=7(x+2).
Answer:
m'=7
Step-by-step explanation:
they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:
m = m'
y-4=7x+14
y=7x+18
y=mx+h
So m = 7
& m' = 7

If the ant were to walk straight down the side of the tower until it reached the ground, how far would the ant travel? Which trigonometric ratio would you use to find this distance? Use the ratio to find the measurement. (4 points: 1 point for the method, 2 points for shown work, 1 point for the answer)
6. Confirm that your answer to question 5 is correct using the Pythagorean Theorem instead of trig ratios. (3 points)
Answer:
The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.
Step-by-step explanation:
You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x
=> x = 50 m / tan(86°)
x = 50 m / 14.30 = 0.98 m

At the beginning of a population study, a city had 390,000 people. Each year since, the population has grown by 1.1%.
Let t be the number of years since start of the study. Let y be the city's population.
Write an exponential function showing the relationship between y and t.
Answer:
t=number of years since start of the study.
y=city´s population.
first year:
y=390,000+0.073(390,000)=390,000(1+0.073) (=418470)
Second year:
y=(390,000(1+0.073) + 0.073(390,000(1+0.073) =
=390,000(1+0.073) (1+0.073)
=390,000(1+0.073)²
(≈449,018.31)
Third year: if you calculate it you would have:
y=390,000(1+0.073)³
Fourth year: if you compute it you would have:
y=390,000 (1+0.073)⁴
t th year:
y=390,000(1+0.073)^t
Answer: y=390,000(1+0.073)^t

Determine the slope of the line passing through (4,-2) and (7,10)?????
Answer: 4
Step-by-step explanation:
(4,-2) will be point 1, (7,10) will be point 2. The order doesn't matter.
slope = y2-y1 / x2 - x1
slope = 10 - (-2) / 7 - 4
slope = 12 / 3
slope = 4
The slope of the line that passing through (4, -2) and (7, 10) is 11/3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
(4, -1) = (a, b) and (7, 10) = (c, d)
Slope:
= (d - b) / (c - a)
= (10 + 1) / (7 - 4)
= 11 / 3
Thus,
The slope is 11/3.
