Answer: g(x) is -x² -3

Step-by-step explanation:

First, you know that the parabola is facing downwards, so the x must be negative.

Next, it is 3 units down from the parent graph, which adds that -3.

All of these add up to get your final equation:

g(x) is -x² -3

Find the values of which satisfy the equation. 2 cos (2B+30°) = -√3 in the domain OP ≤B≤360°

PSYCHO15rus [73]

Answer:

60 and 90

Step-by-step explanation:

$2 \cos(2 \beta + 30) = - \sqrt{3}$

$\cos(2 \beta + 30) = - \frac{ \sqrt{3} }{2}$

$2 \beta + 30 = \cos {}^{ - 1} ( \frac{ - \sqrt{3} }{2} )$

First solution.

$2 \beta + 30 = 150$

$2 \beta = 120$

$\beta = 60$

Second solution

$2 \beta + 30 = 210$

$2 \beta = 180$

$\beta = 90$

If x = 3 units, y = 6 units, and h = 4 units, find the area of the rhombus shown above using decomposition.

eduard

Answer:

= 12 square units

Step-by-step explanation:

Please look at the photo attached below, I think it is fit with your question

To find the area, substitute the values given in the question into the formula given below.

Area = base • height

= x • h

= 3 units • 4 units

= 12 square units

A metal pipe is 1.4 m long. Its internal diameter is 25 mm and thickness 1 mm. If 1 mm³ of the metal weighs 0.02 gm, find the we

<h3>What is Unit of Measurement?</h3>

It is definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

It is given,

A metal pipe is 1.4 m long

Length of metal pipe is 1.4m=1400mm

Its internal diameter is 25 mm

Radius =12.5mm

Thickness=1mm

outer radius=12.5+1=13.5mm

volume of pipe=

V=π(R²−r² )h

V=3.142(13.5²-12.5²)1400

V=3.142(182.25-156.25)1400

V=3.142(26)1400

V=114368.8

1 mm³ of the metal weighs 0.02 gm

So 1.4 m long metal weights 114368.8×0.02=2287.4gm

Hence, the weight of the pipe is 2287.4gm.
