Answer:

a:3

Step-by-step explanation:

12+9=21

2 times 2 is 4, and 4 +3 is 7, so 21 divided by 7 is 3.

Mariana [72]

Answer:

194

Step-by-step explanation:

t63 = t1 + (n - 1)(d)

= 8 + (63 - 1)(3)

= 8 + (62)(3)

= 8 + 186

Answer:

Step-by-step explanation:

Remark

The last digit is 1 3 5 7 9 because the last digit is odd.

The first digit must be a 3 because the number is between 300 and 350

Let the first digit = x

Let the second digit = y

Let the third digit = z

x + y = z

x + y + z = 14 Substitute z for x + y

z + z = 14 Combine

2z = 14 Divide by 2

2z/2 = 14/2

z = 7

The first digit is 3 and the third digit = 7

The middle digit is 3 less than the last digit.

y = 7 - 3 = 4

Jeremy and Arnold are working on a project for math class in which they are to identify the quadratic equation that represents a

denis23 [38]

Answer:

The parabola generated by the expression :

$y=x^2-2x+3$

is the one that better represents a rain gauge above the ground.

Step-by-step explanation:

The function:

a) $y=x^2+11x+24$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

b) $y=-x^2-6x-8$

Direction of parabola: branches pointing down

Location of vertex relative to x-axis: above

So, the parabola doesn't depict a rain gauge off the ground

c) $y=x^2-2x+3$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: two units above

So, the parabola depicts a rain gauge off the ground

d) $y=x^2+4x+4$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: right on the x-axis

So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)

e) $y=3x^2+21x+30$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

How do i find the power of a product?

Artyom0805 [142]

If you mean something like 4^3 * 4^14 you have to obey two rules.

1. The base number must be the same for both numbers making up the product.

2. The powers must be added.

In this case 1 and 2 both can be obeyed.

4^3 * 4^14 = 4^(3 + 14) = 4^17
