Answer:

vertex = (4, 3 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

y = (x - 4)² + 3 ← is in vertex form

with vertex = (4, 3 )

The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angle

lions [1.4K]

Answer:

<A = 35degrees

<B =90degrees

<C = 55degrees

Step-by-step explanation:

Given the ratios of a triangle as 7:18:11

Total ratio = 7+18+11

Total ratio = 36

Since the smallest angle is 35degrees, hence <A = 35degrees

Get angle B;

<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)

<B = 1/2 * 180

<B = 90degrees

Get angle C;

<C = 11/36 * 180

<C = 11 * 5

<C = 55degrees

Hence the value of A, B and C are 35, 90 and 55 degrees repectively

What number must you add to complete the square? x^2+6x=15

Andreyy89

To complete the square you must split the b term in half, then square that answer.

6 is the b term, half of 6 is 3, 3 squared is 9. You will add 9 to both sides of x^2 + 6x = 15

x^2 + 6x + 9 = 24

WILL GIVE BRAINLIST do i do 10-x=2?

Viktor [21]

Answer:

x = 4

Step-by-step explanation:

DE is parallel to AC and intersects the other 2 sides. It divides those sides proportionally, that is

$\frac{BD}{DA}$ = $\frac{BE}{EC}$ , thus

$\frac{10-x}{x}$ = $\frac{3}{2}$ ( cross- multiply )

2(10 - x) = 3x ← distribute left side

20 - 2x = 3x ( subtract 3x from both sides )

20 - 5x = 0 ( subtract 20 from both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

Explain how to draw a line segments that measures 2 7/16 inches

viktelen [127]

9514 1404 393

Answer:

draw the line using a ruler on which you have identified points 2 7/16 inches apart

Step-by-step explanation:

On your ruler graduated in inches with marks at 1/16-inch intervals, locate the 0 mark and the mark 1/16 inch before the half-inch mark between 2 and 3 inches.

Draw your line along the edge of the ruler between the two marks you have identified: 0 and 2 7/16. The line will be 2 7/16 inches long.
