4. If g(x) = - 4x² - 3x + 2, determine g(-2).

Akimi4 [234]

For this case we have a function of the form:

$y = f (x)$

Where:

$f (x) = - 4x ^ 2-3x + 2$

We must find the value of the function when $x = -2$ , that is, $g (-2)$ . So:

$g (-2) = - 4 (-2) ^ 2-3 (-2) +2$

We have to:

$- * - = +\\- * + = -$

So:

$g (-2) = - 4 (4) + 6 + 2\\g (-2) = - 16 + 8$

Different signs are subtracted and the major sign is placed.

$g (-2) = - 8$

Answer:

$g (-2) = - 8$

Step-by-step explanation:

$a \: = \frac{1}{2} \times 5 \times 4 \\ area \: \:of \: base = 10cm {}^{2} \\ volume \: = \frac{1}{3} \times a \: \times h \\ = \frac{1}{3} \times 10 \times 15 \\ = 50 cm {}^{2}$

Mrs. Jones is cutting fabric into triangular bandages for students to practice bandaging in First Aid Class. The dimensions of t

lutik1710 [3]

Answer:

The number of bandages that Mrs Jones can cut out of her piece of fbric without stitching is 6 bandages

Step-by-step explanation:

From the question, the triangular bandage is similar and smaller than the triangular sling

Dimension of triangular sling = 30 × 30 × 45

Whereby one of the shorter sides of the bandage = 18 inches, we have;

18/30 = x/45, Where, x = the long side of the bandage

Therefore, x = 18/30×45 = 27 inches

To cut out triangular shapes, from the fabric, we have;

Angle at triangle base = cos⁻¹(27/(18×2)) = 41.4°

Length of edge of cut fabric per bandage = 27 × cos(90-41.4) = 17.86 in.

Number of bandage that can be cut = 112 / 17.86 = 6.27 bandages

Therefore, number of bandages that can be cut without stitching = 6 bandages.

Identify the semiregular tessellation. HELP ASAP. PLEASE I AM DESPERATE!!

nignag [31]

Answer:

see below

Step-by-step explanation:

A regular tessellation involves repeated use of a single regular polygon to cover the plane.

A semiregular tessellation involves repeated use of two or more regular polygons (in the same order around each polygon vertex) to cover the plane.

The first and third diagrams do not involve regular polygons. The fourth involves only a single regular polygon. Hence the second diagram is the one of interest.
