Find the x- and y-intercept of the parabola y = x² + 4x + 2

Mathematics
1 answer:
Veronika [31]1 year ago
4 0

Answer:

x-intercept = (- 2 + √2, 0) (- 2 - √2, 0)

y-intercept = (2, 0)

Step-by-step explanation:

<u>Given expression</u>

y = x² + 4x + 2

<u>Find the x-intercept</u>

<em>Definition of x-intercept is the point that intersects with the x-axis, which means the y value is 0</em>

(0) = x² + 4x + 2

(x + 2 - √2) (x + 2 + √2) = 0

x = -2 ± √2

Therefore, the x-intercepts are \Large\boxed{(-2+\sqrt{2},~0) } \Large\boxed{(-2-\sqrt{2},~0) }

<u>Find the y-intercept</u>

<em>Definition of x-intercept is the point that intersects with the y-axis, which means the x value is 0</em>

y = (0)² + 4(0) + 2

y = 0 + 0 + 2

y = 2

Therefore, the y-intercept is \Large\boxed{(0,~2)}

Hope this helps!! :)

Find the distance between the point: (-3,1) and (-7,-5)
kotegsom [21]

Answer:

2√13

Step-by-step explanation:

using the distance formula;

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

you plug the numbers in. once done you get 2√13.

A company manufactures penny number 2 nails that are 1 inch in length. The actual length is allowed to vary by up to \displaysty
Diano4ka-milaya [45]

The absolute value equation representing the length of the nail is :

  • \frac{31}{32}  \leqslant x \leqslant 1 \frac{1}{32}

A nail of length 1.05 inches is unacceptable

Actual Length of nail = 1 inch

Allowable variation = 1/32 inches

The minimum allowable length :

actual length - allowable variation

  • 1 -  \frac{1}{32}  =  \frac{31}{32}

The maximum allowable length :

Actual length + allowable variation

  • 1 +  \frac{1}{32}  = 1 \frac{1}{32}

The length of X, of the nail must be follow the equation :

Minimum ≤ X ≤ maximum

\frac{31}{32}  \leqslant x \leqslant 1 \frac{1}{32}

A nail of length 1.05 inches

Maximum nail length = 1 1/32 = 1.031

1.05 > 1.031 ; hence, it is greater than the maximum allowable length and hence, Unacceptabe

PLEASEE HELPP ME IM DESPERATE​
miss Akunina [59]

Answer:

I can help with Q "4" as -

It uses triangle congruence test -  here we use - SAS, as

one side is equal as it is given

both the  angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )
