Answer:
2x^2 + 4x - 64
Step-by-step explanation:
it is telling us to add the functions together so we use this equation:
2x^2 + 7x - 5 + (-8^2) - 3x + 5
after combining like terms we get
2x^2 + 4x -8^2
and then lastly we square the -8 and get
2x^2 + 4x - 64

Four times a number is equal to the number increased by 21. Find the number.
The number is
Let x equal the number
Tip: Go step-by-step
4 times a number is translated to... 4x
Is equal to means =
to the number increased by 21 is... x+21
Your equation is: 4x=x+21
Subtract x from both sides
3x=21
Divide three from both sides
x=7
Check!
4(7) = 7+21
28=28!
Correct!

Water flows into a tank at the rate of 3 litres per minute.
a. If the tank fills completely in 450 seconds what is the capacity of the tank in ml?
A hole is drilled in the bottom of the tank. Water flows out of the hole at a rate of 60 ml per second.
b. How long will the tank take to drain completely if the flow of water IN continues at the same rate?
Answer:
a) 22,500 b) 2250 seconds (or 37.5 minutes)
Step-by-step explanation:
a) There are 1000 ml in a liter.
Therefore, the rate of water flowing in can be 3000 ml per minute. To convert this into per second, we divide 3000 by 60.
This becomes 50 ml per second. If the tank fills in completely in 450 seconds, we multiply 50 by 450 to get how much water in ml was used to fill the tank completely. 50 times 450 = 22,500. Therefore, the capacity of the tank is 22,500.
b) Since water keeps flowing into the tank at a rate of 50 ml per second, and water flows out at a rate of 60 ml per second, we can define the rate flowing out of the tank as 10 ml per second.
Because the maximum capacity of the tank is 22,500 ml, we divide this by 10 ml (the rate flowing out) to get how many seconds it will take for the tank to drain out completely. 22,500 divided by 10 is 2250.
So, it will take 2250 seconds for the tank to drain completely. In minutes, this becomes 37.5 minutes.
There is still controversy about whether or not Pluto should be considered a planet. Although planets are mainly defined by their orbital path (the condition that prevented Pluto from remaining a planet), the issue of size is something to consider. The table below lists the planets, including Pluto, and their approximate diameters in meters.
Planet Approximate Diameter (m)
Mercury 4.88 × 10^6
Venus 1.21 × 10^7
Earth 1.28 × 10^7
Mars 6.79 × 10^6
Jupiter 1.43 × 10^8
Saturn 1.2 × 10^8
Uranus 5.12 × 10^7
Neptune 4.96 × 10^7
Pluto 2.3 × 10^6
a. Name the planets (including Pluto) in order from smallest to largest.
b. Comparing only diameters, about how many times larger is Jupiter than Pluto?
9514 1404 393
Answer:
a) Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter
b) 62
Step-by-step explanation:
When all the numbers are in scientific notation, as these are, the numbers with the smallest exponent are smaller. If numbers have the same exponent, the number with the smaller mantissa is smaller.
a) least-to-greatest diameter, the order is ...
Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter
__
b) The ratio of diameters of Jupiter and Pluto is ...
(1.43×10^8)/(2.3×10^6) = 6.2×10^1 = 62
Jupiter's diameter is about 62 times that of Pluto.

him or her how to divide 2/3 by 1/6
9514 1404 393
Answer:
invert and multiply, oruse a common denominatorStep-by-step explanation:
There are two ways you can divide 2/3 by 1/6.
1) Division by a number is the same as multiplication by its reciprocal. The reciprocal of a fraction is the fraction obtained by swapping the numerator and denominator. So, division by 1/6 is the same as multiplication by 6/1.
2/3 ÷ 1/6 = 2/3 × 6/1
The result of this multiplication is the product of the numerators divided by the product of the denominators:
2/3 × 6/1 = (2×6)/(3×1) = 12/3 = 4
__
2) The fractions can be expressed with the same denominator. Then their quotient is the quotient of their numerators.
2/3 = 4/6
2/3 ÷ 1/6 = 4/6 ÷ 1/6 = 4 ÷ 1 = 4

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3,5) and
B(5, 1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =
Step-by-step explanation:
the equation is
y = ax + b
a is the slope of the line. this is the ratio y/x indicating how many units y changes, when x changes a certain number of units.
so, when we go from A to B, x changes 2 units (from 3 to 5), and y changes -4 units (from 5 to 1).
so the slope is -4/2 = -2
now or equation looks like
y = -2x + b
to get b we use one of the points in the equation. e.g. B
1 = -2×5 + b = -10 + b
b = 11
so, our full equation is
y = -2x + 11

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?
Answer:
660.4 mm
Step-by-step explanation:
Since 1 inch is equal to 25.4 millimeters, we can multiply 25.4 by 26 to see how many millimeters 26 inches is. You can also think of this as a proportion:
26:x = 1:25.4
26.4 times 26 is equivalent to 660.4, so we can conclude that 26 inches are equivalent to 660.4 millimeters.

For three consecutive even integers, -4 times the sum of the first and third integers is 192. What is the middle integer?
Answer: Middle integer = -24
Step-by-step explanation: First understand the formula for finding three consecutive even numbers.
Formula used: -4(n+n+4)=192
Let's solve your equation step-by-step.
−4(n+n+4)=192
Step 1: Simplify both sides of the equation.
−4(n+n+4)=192
(−4)(n)+(−4)(n)+(−4)(4)=192(Distribute)
−4n+−4n+−16=192
(−4n+−4n)+(−16)=192(Combine Like Terms)
−8n+−16=192
−8n−16=192
Step 2: Add 16 to both sides.
−8n−16+16=192+16
−8n=208
Step 3: Divide both sides by -8.
−8n
−8
=
208
−8
n=−26
Now find the middle integer.
Formula used: n+n+2+n+4
-26+(-26)+2+(-26)+4
-26+(-24)+(-22)
Middle integer=-24
Answer:
-24

Write a 5 sentence Summary:
Describe the transformation that exist a negative is multiplied outside of the function.
Answer:
The negative sign outside the absolute value function causes a few different things when multiplied. When a negative is multiplied outside of the function, the transformation that exists will be a vertical reflection. A horizontal shift to the left 1 unit will happen because of g(x)=f(x+1). The graph will make a vertical shift down 2 units because of g(x)=f(x)−2. The value of (a) would be -1 and since it is less than 1, and it causes the graph to be wider because of vertical compression. Placing a minus sign outside absolute value bars gives you a negative result.

Answer:
3x + y = - 9
Step-by-step explanation:
y - 6 = -3 (x + 5)
Distribute the -3
y - 6 = -3x - 15
Add 3x to both sides
3x + y - 6 = -15
Add 6 to both sides

A cable company technician gave 3:00PM to 7:00PM as his arrival time. The arrival time is uniformly distributed. What is the probability that he arrives exactly at 4:00PM
The probability that the technician arrives exactly at 4:00 pm is 1/5.
What is probability?Probability is the chance of occurring a certain event out of the total no. of events that can occur in a given context. The probability of an event is always greater than equal to zero and less than equal to one.
If we distribute arrival time uniformly in terms of hours the no. of sample space N(s) = 5. (3:00pm, 4:00pm, 5:00pm, 6:00pm, 7:00pm).
∴ The probability that he arrives exactly at 4:00 pm is,
= 1/5.
The probability of arriving at 4:00 pm is 1/5.

Determina la media aritmética, mediana y moda
Utilizando conceptos estadísticos, se encuentra que
La media es de 17.5 cuadernos vendidos.La mediana es de 17.5 cuadernos vendidos. La moda es de 17.5 cuadernos vendidos.La media viene dada por la suma del punto medio de cada intervalo multiplicada por su frecuencia relativa.
O sea, [tex]\frac{5 + 10}{2} = 7.5[/tex] multiplicado por [tex]\frac{3}{30}[/tex] hasta [tex]32.5[/tex] multiplicado por [tex]\frac{1}{30}[/tex]. Entonces:
[tex]M = 7.5\frac{3}{30} + 12.5\frac{7}{30} + 17.5\frac{10}{30} + 22.5\frac{8}{30} + 27.5\frac{1}{30} + 32.5\frac{1}{30}[/tex]
[tex]M = \frac{7.5(3) + 12.5(7) + 17.5(10) + 22.5(8) + 27.5 + 32.5}{30} = 17.5[/tex]
