How Do I Solve This Problem Ive Been Trying For A While

Answers

Answer 1

Answer:

Your idea of building a table is not a bad start if you want accurate points.

Else, it's a parabola. It's y intercept has the non-zero coordinate equal to the constant term (red dot on the graph).

It's x intersects you find by solving

[tex]2x^2+12x+4 = 0 \rightarrow x^2+6x+2=0\\ x_1_,_2= -3\pm\sqrt7\\x_1\approx -0.35\\x_2\approx-5.35[/tex]

(green dots).

Simmetry axis has equation [tex]x=-\frac{b}{2a} = -\frac{12}{4}=-3[/tex] (orange line).

Vertex sits on this line and is in the parabola, so it's other coordinate is

[tex]2(-3)^2+12(-3)+4= -14[/tex] (orange dot).

At that point you either continue with the table, or you go for a "good enough" and try to draw a better looking parabola than mine.

The function below describes the relationship the height H and the width W of a rectangle with area 75 sq. units. H(w)= 75/w what is the domain of the function right answer gets Brainly

Answers

The domain of the function is w > 0

How to determine the domain?

The function is given as:

H(w) = 75/w

For the function to have a real value, the value of w cannot be 0

i.e.

[tex]w \ne 0[/tex]

Also, the value of w cannot be negative because width cannot be negative

This means that the possible values of w are greater than 0

Hence, the domain of the function is w > 0

Circle A has a diameter of 9 inches, a circumference of 28.26 inches, and an area of 63.585 square inches. The diameter of circle B is 5 inches, the circumference is 15.70
inches, and the area is 19.625 square inches..
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)

Answers

Step-by-step explanation:

area of a circle

A = pi × r²

circumference of a circle

C = 2 × pi × r

r = diameter / 2 (the radius is half of the diameter)

circle A

A = 63.585 = pi × 4.5² = pi × 20.25

pi = 63.585 / 20.25 = 3.14

C = 28.26 = 2 × pi × 4.5

pi = 28.26 / (2 × 4.5) = 28.26 / 9 = 3.14

circle B

A = 19.625 = pi × 2.5² = pi × 6.25

pi = 19.625 / 6.25 = 3.14

C = 15.7 = 2 × pi × 2.5

pi = 15.7 / (2 × 2.5) = 15.7 / 5 = 3.14

pi is always the same for every circle of any size. it is a natural constant defining the circumference and area of every circle in relation to the actual radius or diameter.

x is old cube's side before enlargement x+8 is side length after enlargement

Option A

Answer:

17 centimetres

A square has all sides similar.

area of square = side²

Let the original length be xwhen increased, one side new length → x + 4 + 4 → x + 8

solve:

(x + 8)² = 625

x + 8 = √625

x + 8 = 25

x = 25 - 8

x = 17

To calculate discounts, you multiply the percentage of the discount as a decimal with the price of the product.

In this particular case:

0.40 [percentage of discount] x $1580 [original cost] = $632 (the amount of the discount) $1580 - $632 = $698 [new price after discount is applied]

*Note that:

[tex] \boxed{ \sf \: area \: of \: rectangle = length \times breadth}[/tex]

Now,

Length = 2/3 (Given)Width = 3/4 (Given)

Solve ;

[tex] \tt \implies \: area = \frac{2}{3} \times \frac{3}{4} [/tex]

[tex] \tt \implies \: area = \frac{2 \times 3}{3 \times 4} [/tex]

[tex] \tt \implies \: area = \frac{6}{12} = \frac{1}{2} [/tex]

Thus, The carpet takes up 1/2 unit² area of the classroom...~

Answer:

1/2 or half of the classroom area

Step-by-step explanation:

Step 1: Calculating area of carpet

Let total length be l and width be w.

Now, according to the problem,

Area = 2l/3 x 3w/4

= 2lw/4

Step 2: Take area of carpet and area of classroom as a ratio

(2lw/4) / lw

= 2/4

= 1/2

Therefore, the carpet takes up 1/2 or half of the classroom area.

Answers

The distance of sparky to the fire is 99.445 feet

Application of SOH CAH TOA identity

Given the following parameters

The angle of depression = 6  degrees

If Sparky is looking over the fairly level, hence the hypotenuse is 100 foot

Required

Distance from spark tower to the fire

Using the expression below

Cos 6 = D/100

D = 100cos6

D = 100(0.9945)
D = 99.45foot
