Step-by-step explanation:

C.

x² + 10x + 25 = (x+5)²

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

so, your 1st eqn. is 3x + 5y = 17.75

2nd eqn. is 4x+ 2y = 12

Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5

So: 6x+10y=35.5

-20x-10y=-60

=-14x=-24.5

x=24.5/14 = 1.75

Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75

y = 2.5

Answer:

a=116.5°

b=116.5°

Step-by-step explanation:

360-95-32=233

Answer:

y/-3 = 1/6

y = 1/6 × 3

y = 0.5

Answer:

-1/2 and -0.5

Explanation :

Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.

y ÷ -3 = 1/6

0.5 ÷ -3 = 1/6

-1/6 = 1/6 ---> NO

y ÷ -3 = 1/6

-1/2 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-0.5 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-18 ÷ -3 = 1/6

6 = 1/6 ---> NO

Hope this helps, and stay safe, happy, and healthy, thank you :) !!

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:

-

Step-by-step explanation:

-

The surface area of the cone is 16π square units.

The surface area of the cone is given by;

⇒ Area = πrl + πr²

Here, We have;

A right cone has a slant height of 6 and a radius of 2.

Substitute all the values in the formula

⇒ Area = πrl + πr²

⇒ Area = π x 2 x 6 + π x 2²

⇒ Area = 16π

Hence, The surface area of the cone is 16π square units.

Answer: x^2/9 + y^2/4 = 1

Step-by-step explanation:

Answer: [tex]\frac{x^{2} }{9} +\frac{y^{2} }{4} =1[/tex]

Step-by-step explanation:

Substitute the x-value of the vertex for a, and the y-value of the co-vertex for b in the standard equation of a horizontal ellipse [tex]\frac{x^{2} }{a^{2}} +\frac{y^{2}}{b^{2}} =1[/tex].

[tex]\frac{x^{2} }{a^{2}} +\frac{y^{2}}{b^{2} } =1[/tex]  

[tex]\frac{x^{2} }{-3^{2}} +\frac{y^{2} }{2^{2} } =1[/tex]

[tex]\frac{x^{2} }{9 } +\frac{y^{2} }{4} } =1[/tex]

The answer is, X = 12.

hope it helps.

Answer:

x = 12

Step-by-step explanation:

simlify 4/3 * (3x-12)

4x - 16 = 2x + 8

combine like terms, so subtract 2x by 4x

2x - 16= 8

then finish combining like terms, so 16 plus 8

2x = 24

divide 24 by 2

x = 12

Answer:

Approximately $242,000

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:

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).

Angle C is 90 degrees so angle A and B are both the same length I think.

Since 180 degrees is the total because it is a triangle, then 180-90=90/2=?

9514 1404 393

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.

Answer:

B and C

Step-by-step explanation:

Not A because the side lengths aren't multiples.

Not D because it would be congruent, unless it had different angles, but then similar shaps must have the same angles
