The equation of a parabola with vertex at (-2, 2) and passes through (-3, 5) and (-1, 5) is y = 3x² + 12x + 14. The value of a in the equation is 3.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The graph of a quadratic equation has the shape of a parabola. The standard quadratic equation has the form:

y = ax² + bx + c

The equation of a parabola with vertex at (-2, 2) and passes through (-3, 5) and (-1, 5) is y = 3x² + 12x + 14. The value of a in the equation is 3.

Answer:

x =1

Step-by-step explanation:

Assuming the figures are similar, we can use ratios to solve

x        2

---- = -----

4         8

Using cross products

8x = 2*4

8x = 8

Divide by 8

8x/8 = 8/8

x=1

Trapezoid ZOID is congruent to trapezoid TRAP. If vertices 2 and have coordinates (0, -2) and (0, -5) respectively, which of the
vlada-n [284]

The trapezoids are congruent if the corresponding sides of each trapezoid are equal

The option that gives the possible coordinates for the vertex <em>I</em> is the option;

\underline{(-4.5, -5)}

Reason:

The given coordinates of the trapezoid TRAP = T(3, 5), P(3 2), R(6, 5), and A(7.5, 2)

The given coordinates of the trapezoid ZOID = Z(0, -2), and D(0, -5)

Required: The possible coordinates for a vertex on ZOID

Solution:

The given points of the trapezoid are the height of the trapezoid ZOID

The possible vertex of <em>I</em>, and <em>O</em> are;

  • I(4.5, -5), I(-4.5, -5), O(3, -2), O(-3, -2)

Therefore;

The option that gives the possible coordinates (position) of a vertex <em>I</em> is the option \underline{(-4.5, -5)}

Arrange the numbers in increasing order 14.204 14.200 14.240 14.210
Crank

Answer:

Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.

Step-by-step explanation:

Given : Numbers 14.204, 14.200, 14.240, 14.210.

To find : Arrange the numbers in increasing order ?

Solution :

Arrange the numbers in increasing order is defined as arranging numbers from the smallest number to the largest number.

If we see the numbers 14.204, 14.200, 14.240, 14.210.

The number before decimal is same so we arrange according to after decimal,

14.200<14.204<14.210<14.240

Therefore, Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.
