Find the axis of symmetry, vertex, domain, range to y=x^2-6x=+7
Wewaii [24]
<span>First, we want to get the +7 on the other side of the equal sign, so we subtract 7 on both sides.

</span><span>x^2 - 6x<span> - 7</span> = 7 <span>- 7
</span>x^2 - 6x - 7

Next, we use the formula \frac{-b}{2a} to find the axis of symmetry.
Because this is a quadratic equation, it is in the form
ax^2 + bx + c
We need to identify the a b and c values.

</span><span>ax^2 + bx + c
</span><span>(1)x^2 - 6x - 7
a = 1, b = -6 and c = -7.

Substitute the a and b values into the equation to find the axis of symmetry.

</span>\frac{-b}{2a}<span> = \frac{-(-6)}{2(1)}</span><span> = \frac{6}{2} = 3

The axis of symmetry is is 3.
The axis of symmetry is also the x coordinate of our vertex.
To find the y coordinate, substitute the axis of symmetry we found into the original quadratic equation by replacing each x variable with 3.

</span><span>x^2 - 6x - 7
(3)^2 - 6(3) - 7
9 - 18 - 7
-16

The vertex is (3, -16)

</span>The domain represents all possible x-values of the parabola. Because our function will always be getting wider graphically, it will cover every possible x value. The domain is all real numbers.

The range represents all possibly y values. The parabola will always be going up, but it only goes as far down as to the minimum vertex, making the range all real numbers that are greater than or equal to −16. The range can be written as y ≥ −16.

So,

Axis of symmetry: 3
Vertex: (3, -16)
Domain: All real numbers
Range: y ≥ −16

Hope this helps!!

Element X decays radioactively with a half life of 6 minutes. If there are 790 grams of Element X, how long, to the nearest tent
frosja888 [35]

Answer:

It takes 27 minutes for the element to decay to 35 grams

Step-by-step explanation:

Given:

Initial amount  =  790 grams

Final amount =  35 grams

Half life =  6 minutes

To find:

Time taken for the element to reduce into 35 grams  = ?

Solutions

Time taken = half life  \times \frac{ log(\frac{ initial amount}{final amount})}{log(2)}

On substituting the values given, Time taken  

= 6 \times \frac{log(\frac{790}{35})}{log(2)}

= 6 \times \frac{log(22.57)}{log(2)}

= 6 \times 4.496

= 26.97

= 27 minutes

Marco thinks the total number of runs a team scores in a season is a better indicator of how many wins it will have in that seas
FrozenT [24]
This is a fair assumption, but not true in every instance. Since home runs do not indicate how many runs score, which are the decider in a win or a loss, they are less accurate at predicting.

Someone help me please
Masteriza [31]

Answer:

(5,1)

Step-by-step explanation:

Hi there!

Midpoint = \displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) where the two endpoints are (x_1,y_1) and (x_2,y_2)

Plug in the given information:

Midpoint = (5,3), Endpoint = (5,5)

(5,3)=\displaystyle (\frac{5+x_2}{2},\frac{5+y_2}{2} ) where  (x_2,y_2) is the other endpoint

Solve for x_2:

\displaystyle \frac{5+x_2}{2} =5\\\\5+x_2 =10\\x_2 =5

Solve for y_2:

\displaystyle\frac{5+y_2}{2}=3 \\\\{5+y_2}=6\\y_2=1

Therefore, the other endpoint (x_2,y_2) is (5,1).

I hope this helps!

Can someone help me with this problem please? Thank you!
Olenka [21]

Answer:

50

Step-by-step explanation:

since the Pythagorean theorem is

c= √a^2+b^2

b is the bottom line (48)

a is the right line (14)

c is the top line (c)

plug that in

c = √14^2 + 48^2

then do the exponets

14^2 = 14 * 14 = 196

48^2 = 48 * 48 = 2304

then add them together

196 + 2304 = 2500

c = √2500

the sqrt of 2500 is 50 (50 * 50 = 2500)

c = 50

your answer is 50

hope this helps:)
