Step-by-step explanation:
h(x) = x^2 - 5x + 7
(a) h(2) = (2)^2 - 5(2) + 7
= 4 - 10 + 7
= 1
(b) h(-5) = (-5)^2 - 5(-5) + 7
= 25 + 25 + 7
= 57
(c) h(-8) = (-8)^2 - 5(-8) + 7
= 64 + 40 + 7
= 111
La siguiente funcion representa el costo del alquiler de un auto, en soles, en funcion del X de dias que se requiera = F (X) = 50 + 80 X
Answer:
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Step-by-step explanation:
La siguiente función representa el costo del alquiler de un auto, en soles, en función del número x de días que se requiera: f(x) = 50 + 80x. ¿Cuánto vale su pendiente y qué representa? a) 130; representa que, por cada día de alquiler, el costo se incrementa en 130 soles. b) 80; representa que, por cada día de alquiler, el costo se incrementa en 80 soles. c) 50; representa que, por cada día de alquiler, el costo se incrementa en 50 soles. d) 30; representa que, por cada día de alquiler, el costo se incrementa en 30 soles
Answer:
La función es una función lineal. Una función lineal tiene la forma y = mx + b, donde m es la tasa de cambio de y con respecto a x, b es el valor de y en x = 0, x es una variable independiente (no depende de otras variables) ey es una variable dependiente (depende de otras variables)
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Which is the best estimate of 61.4 + 88.3?
A. 100
B. 140
C. 150
D. 200
C.150
Step-by-step explanation:
It is the closest to the answer and you would get closest to that even without really needing to work anything out
The best estimation of summation 61.4 + 88.3 after rounding to the nearest whole number is 150.
How do round any digit?To round up or down tens place then we need to look at the unit place if it is less than 5 then we need to keep it as it and if it is greater than 5 then we need to round up tens digit.
Given the sum,
61.4 + 88.3
61.4 + 88.3 = 149.7
Now the decimal place is 7 and if the decimal place is greater than 5 then we can round up the digit.
So,
149.7 → 14(9 + 1) = 150
Hence "Summation 61.4 + 88.3 is best approximated as 150 after being rounded to the next whole number".

Calculate the force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg
The force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg is 5.27 * 10⁻¹⁰ N
Newton's law of gravitation is given by:
F = Gm₁m₂/r²
Where F is the force, m₁, m₂ are masses, r is the distance between the two masses and G is the gravitational constant = 6.67 * 10⁻¹¹ Nm²/kg²
Given that m₁ = m₂ = 0.45 kg, r = 0.08 + 0.08 = 0.16 m, hence:
F = 6.67 * 10⁻¹¹ Nm²/kg² * 0.45 kg * 0.45 kg / 0.16²
F = 5.27 * 10⁻¹⁰ N
The force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg is 5.27 * 10⁻¹⁰ N

2 + 1.25f =10-2.75f
Answer:
f = 2
Step-by-step explanation:
2 + 1.25f =10-2.75f
Add 2.75f to each side
2 + 1.25f+2.75f =10-2.75f+2.75f
2+ 4f = 10
Subtract 2 from each side
2+4f-2 = 10-2
4f = 8
Divide each side by 4
4f/4 = 8/4
f = 2

The range has to be within 1-5, if its over, we know we won't have to get the wrong answer. For me, I honestly guessed the number 3, but then I had to put in each number in the equation. 2 was the solution, because they ended up the same.
2 + (1.25 * 2)
2 + 2.5 = 4.5
10 - (2.75 * 2)
10 - 5.5 = 4.5
4.5 = 4.5
Therefore the answer is 2.

3x + 4.7 < -1.5x + 6.5
Answer:
x < .4
Step-by-step explanation:
Please mark Brainliest when you’re able :)
Answer:
Step-by-step explanation:
Step 1 - replace the < with an =
3x + 4.7 = -1.5x + 6.5
Step 2 - subtract 4.7 from each side, and add 1.5x to each side
3x + 1.5x = 6.5 - 4.7
4.5x = 1.8
Step 3 - divide each side by 4.5
x = 1.8/4.5
x = .4
Step 4 - change the = back to <
x < .4
Just make sure when you do it this way you check the answer because if you solved by subtracting 3x and subtracting 6.5 you would end up with .4 = x this .4 < x which is false. So depending what number you get always plug in a number bigger and smaller into the original to check. In this case 0 and 1 work.
3(0) + 4.7 < -1.5(0) + 6.5
4.7 < 6.5 which is true.
3(1)+ 4.7 < -1.5(1) + 6.5
3+4.7 < -1.5 + 6.5
7.7 < 5 which is false
So we know the direction on our < is right.
