Express y = -2x² - 4x + 7 in the form of perfect square and find the maximum points.

Marat540 [252]

Answer:

Maximum: (-1,9)

Step-by-step explanation:

Vertex form of the quadratic function

If the graph of the quadratic function has a vertex at the point (h,k), then the function can be written as:

$y=a(x-h)^2+k$

Where a is the leading coefficient.

We are given the following function:

$y =-2x^2-4x+7$

To find the vertex, we need to complete squares. First, factor -2 on the first two terms:

$y =-2(x^2+2x)+7$

The expression in parentheses must be completed to represent the square of a binomial. Adding 1 and subtracting 1:

$y =-2(x^2+2x+1- 1)+7$

Taking out the -1:

$y =-2(x^2+2x+1)+2+7$

Factoring the trinomial and operating:

$y =-2(x+1)^2+9$

Comparing with the vertex form we have

Vertex (-1,9)

Leading coefficient: -2

Since the leading coefficient is negative, the function has a maximum value at its vertex, i.e.

Maximum: (-1,9)

Area for a kite I don’t know how to find the area pls help

dusya [7]

Answer:

63.966

Step-by-step explanation:

Area of a kite is

$\frac{pq}{2}$

where p and q are the diagonals.

The horinzontial diagonal is 8.

We need to find the vertical diagonal length.

The top triangle diagonal measure is

${4}^{2} + {x}^{2} = {7}^{2}$

$16 + {x}^{2} = 49$

${x}^{2} = 33$

$x = \sqrt{33}$

The bottom triangle diagonal measure is

${4}^{2} + {x}^{2} = {11}^{2}$

$1 6 + {x}^{2} = 121$

${x}^{2} = 105$

$x = \sqrt{105}$

Add the two diagonals.

$\sqrt{105} + \sqrt{33}$

Substitute this in for the formula

$\frac{8 \times ( \sqrt{105} + \sqrt{33} }{2}$

Which simplified gu

Answer number 1 or 2 or both please<3

m_a_m_a [10]

Answer:

1. 1.96 g/L

2. 1 g/cm³

Step-by-step explanation:

Density is found by dividing mass by volume: d = m/v.

We know that the mass is 0.196 grams, while the volume is 100 mL.

Converting the volume to liters, we get:

100 mL = 0.1 L

Then, applying our density formula:

d = m/v

d = 0.196 g / 0.1 L = 1.96 g/L

Here, we know that the mass is 27 grams. However, we don't know the volume, which we need to find.

The block of wood is 3 cm on all sides, which means it's a cube. The volume of a cube is denoted by V = s³, where s is the side length. Here, s = 3, so V = s³ = 3³ = 27 cm³.

Applying our density formula gives:

d = m/v

d = 27 g / 27 cm³ = 1 g/cm³
