Answer:

Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).

Answer:

a=116.5°

b=116.5°

Step-by-step explanation:

360-95-32=233

233÷2=116.5

a and c are equal, so both are 116.5

Answer:

b) -2x = 20, negative 2x is equal to 20

(Because, -2x = -20)

Step-by-step explanation:

Given equation,

→ 2x + 14 = 4x - 6

Now the value of x will be,

→ 2x + 14 = 4x - 6

→ 2x - 4x = -6 - 14

→ -2x = -20

→ x = (-20)/(-2)

→ x = 20/2

→ [ x = 10 ]

Hence, the value of x is 10.

2 cot²(t ) sin(t ) - cot²(t ) = 0

cot²(t ) (2 sin(t ) - 1) = 0

cot²(t ) = 0   or   2 sin(t ) - 1 = 0

cot(t ) = 0   or   sin(t ) = 1/2

cos(t ) / sin(t ) = 0   or   sin(t ) = 1/2

cos(t ) = 0   or   sin(t ) = 1/2

[t = cos⁻¹(0) + 2nπ   or   t = cos⁻¹(0) - π + 2nπ]

  or   [t = sin⁻¹(1/2) + 2nπ   or   t = π - sin⁻¹(1/2) + 2nπ]

(where n is any integer)

t = π/2 + 2nπ   or   t = -π/2 + 2nπ   or   t = π/6 + 2nπ   or   t = 5π/6 + 2nπ

Note that the first two families of solutions overlap and can be condensed, so that

t = π/2 + nπ   or   t = π/6 + 2nπ   or   t = 5π/6 + 2nπ

Answer:

x > 9

Step-by-step explanation:

6x + 9 < 7x .    

-6x         -6x             <---- Subtract 6x from both sides.

       9 < x                <----- 7x - 6x = 1x (which can also be written as just x)

Therefore the answer is x > 9.

Approximately $242,000

Answer:

(0,-9), x = 0, (-3,0), (3,0), domain, -9

Step-by-step explanation:

Complete the square and you can read everything off the equation,

y  = x^2 - 9

= (x - 0)^2 - 9

Vertex : (0,-9)

Axis of symmetry: x = 0

x-intercepts:  x^2 = 9 -> x = ±3

Left x-intercept: (-3,0)

right x-intercept: (3,0)

Since the function is well-defined for any x-values,

we can say that its domain is the set of all real numbers.

Since the minimum point of the graph is (0,-9),

The range will be greater than or equal to -9.

Answer:

x - 8 = 0

Step-by-step explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]

Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

Answer:

The answere is C.

Step-by-step explanation:

It is right on edge

Answer:

5 ft

Step-by-step explanation:

area = L * W * H

35    =  L * W

Volume = (L *W) * H

since we have already found that L * W is already 35

175 = 35 * H

Divide by 35  on both sides to get H

175/35 = 5

answer = 5 ft

Answer:

I think 235.5 mm cubed

Step-by-step explanation:

The formula for the volume of a cone is V=1/3hπr².

1/3 x 9 x π x 5² =

1/3 x 9π x 25 =

1/3 x 225π =

75π

let's say π=3.14

75 x 3.14 = 235.5

Answer:

  64 degrees

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relations between triangle sides and trig functions. Here, the marked sides are opposite and adjacent to the marked angle, so the relevant relation is ...

  Tan = Opposite/Adjacent

  tan(θ) = 29/14

To find the angle measure, we use the inverse function. It may be called tan⁻¹ on your calculator. It also goes by the name "arctangent." The term "arctan" can be thought of, or even pronounced as, "the angle whose tangent is ...".

  θ = arctan(29/14) = 64.23°

The measure of angle θ is about 64°.

_____

Additional comment

The default units for angle measure are radians in most spreadsheets and on-line calculators. You need to make sure your hand-held calculator mode is set to give angles in the units you want. Here, we've given the angle in degrees, which is usually what is expected in problems like this.
