Only find the vertex and axis of symmetry

Mathematics
1 answer:
lara [203]2 years ago
5 0

Answer:

vertex (5,2)

axis of symmetry: x=5

Step-by-step explanation:

vertex (h,k)

y = a(x - h)² + k

f(x)=(x-5)²+2        a = 1     h = 5      k = 2

vertex (5 , 2)

The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

x = 5

Express the probability that a die wil land on a number less than 5 as a fraction
Rashid [163]

Answer:

\frac{2}{3}

Step-by-step explanation:

Values less than 5 on a die are 1, 2, 3, 4 ← 4 values out of a possible 6

P( < 5) = \frac{4}{6} = \frac{2}{3} in simplest form

PLEASE HELP A GIRL OUT!!! What is the best estimate for the value of the expression?
Ivenika [448]

Answer: -2(1/2)

Step-by-step explanation:

I CAN HELP A GIRL OUT!

anyways...

calculate the difference first.

(-13/12) - 14/9

then, rewrite the expression.

-13/12 - 14/9

the solution is -95/36.

when it's converted to decimal form, it turns into -2.638. so, our BEST estimate for the value of the expression is -2(1/2)       (the second option)

Explain why the quadratic relation y=2x^2+3x+5 would have no zeros
alex41 [277]

Complete the square to rewrite the quadratic:

2 <em>x</em>² + 3 <em>x</em> + 5 = 2 (<em>x</em>² + 3/2 <em>x</em>) + 5

... = 2 (<em>x</em>² + 3/2 <em>x</em> + 9/16 - 9/16) + 5

... = 2 (<em>x</em>² + 3/2 <em>x</em> + (3/4)²) + 5 - 9/8

... = 2 (<em>x</em> + 3/4)² + 31/8

Any real number squared becomes non-negative, so the quadratic expression has a minimum value of 31/8, which is greater than 0, and so there are no (real) <em>x</em> for which <em>y</em> = 0.

Solve for w in the proportion.<br> W/14 = 21/42 W = ?
Nataly [62]

Answer:

W = 7

Step-by-step explanation:

1) Simplify 21/42 into 1/2

w/ 14 = 1/2

2) Multiply both sides by 14.

W = 1/2 · 14

3) Simplify

W = 14/29

4) Simplify (again)

W = 7
