which of the following numbers must be added to complete the square in the equation below x^2+16x=5​

Answer:

239

Step-by-step explanation:

SP is the diameter so Arc RP is supplementary to Arc SR

[tex]31 + x = 180[/tex]

[tex]x = 149[/tex]

Arc PQ is supplementary to Arc SQ so

[tex]90 + x = 180[/tex]

[tex]x = 90[/tex]

Arc Addition:

[tex]149 + 90 = 239[/tex]

Answer:

D. y = 1/4x + 6​

Step-by-step explanation:

In the linear equation y = mx + b, m is the slope.

A graph will be steeper if it has a larger slope, and less steep if it has a smaller slope.

So, to find which equation has the least steep graph, find which one has the smallest slope.

Out of the 4 equations, the smallest slope is 1/4. Although -7 is the smallest number, it still has a steep slope. The negative sign just makes it go in the other direction.

So, the equation with the least steep graph is D. y = 1/4x + 6​

Answer:D

Y= 1/4x +6

Step-by-step explanation:

Answer:

Step-by-step explanation:

Graph given for the function has three segments therefore, its a piecewise function.

For a segment lying between (2, ∞)

Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                            = [tex]\frac{2}{1}[/tex]

                            = 2

y-intercept of the line = -2

Therefore, equation of the line will be,

y = 2x - 2

Second segment is a straight line,

Equation of the line will be,

y = 4

Third segment is a straight line.

Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                            = [tex]\frac{1}{1}[/tex]

                            = 1

Equation of the line will be,

y = x + b

Since, this line passes through a point (6, 7)

7 = 6 + b

b = 1

Therefore, equation of the third segment will be,

y = x + 1

So the piecewise function will be,

f(x) = 2x - 2   For x < 2

        4     For 2≤ x ≤ 5

        x + 1   For x > 5

Answer:

Step-by-step explanation:

The translation vector < 4, - 2 > means each point is being moved 4 units to the right and 2 units down.

X(0, 3) ------> X' ( 0 + 4, 3 - 2 ) = X'(4, 1)

Y( - 1, 1) ------> Y' ( - 1 + 4, 1 - 2 ) = Y'(3, - 1)

Z( - 3, 4) -----> Z' ( - 3 + 4, 4 - 2 ) = Z'(1, 2)

Answer:

Because this fraction is where its value is at

Step-by-step explanation:

0.44 54. 5/6 0.86

Step-by-step explanation:

5/6 = 0.8333 which is smaller than

0.86

Answer:

-16

Step-by-step explanation:

Given that the first term is -10 .

=> a1 = -10 .

General formula:-

=> a_n = a_n -1 + 3 .

Therefore , the common difference :-

=> 2nd term - 1 term

=> a_n-1 - a_n = -3

nth term of the AP is ,

=> T_n = a + (n-1)d

=> T_3 = -10 + (3-1) × -3

=> T_3 = -10 + -6

=> T_3 = -16 .

Answer:

The answer is 100.5 [tex]in^{3}[/tex].

Step-by-step explanation:

To solve for the volume of the cylinder, use the cylinder volume formula, which is V = [tex]\pi r^{2} h[/tex].

Next, plug in the information given from the problem, and the formula will look like V = [tex](\pi) (2 in^{2}) (8 in)[/tex].

Then, solve the equation, and the answer will be 100.5 [tex]in^{3}[/tex].  

Answer:

2 6 10

Step-by-step explanation:

have :

a + b +c  = 18

a*b*c = 120

a+c = 2*b => 3*b = 18 => b = 6

then a = 2, c = 10

Answer:

Independent - hours of watching television per weekend

dependent - mathematics marks

Step-by-step explanation:

The independent variable is the variable that the person carrying out an experiment changes or manipulates. the independent variable usually have a direct effect on the dependent variable

The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable.

The number of hours students spend watching tv would affect their performance on the test because it would determine the number of hours the students spend studying.

thus, the hours spent watching tv is the independent variable while the dependent variable is the score of the students

qnd nice pc

Step-by-step explanation:

Hey there!

Given;

Distance (d) = 450 km = 450*1000 = 450000 m

Time(t) = 5 hours = 5*60*60 = 18000s

Now;

Speed (s) = Distance (d) /Time(t)

Or, s = 450000/18000

Or, s = 25m/s.

Therefore, the speed is 25m/s.

Hope it helps!

Answer:

The car has a velocity of 25 m/s.

Step-by-step explanation:

There are two ways to solve this problem.

First way :

450km = 450.000m

5h = 5x 3.600s =18.000s

v = s/t = 450.000 / 18.000 = 25m/s

Second way :

Velocity = speed/time = 450 / 5 = 90 km/h

90/3.6 = 25 m/s

Either way, the car has a velocity of 25 m/s.

Answer:

(x - 5)² + (y - 5)² = 18

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (5, 5) , then

(x - 5)² + (y - 5)² = r²

r is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (5, 5) and (x₂, y₂ ) = (8, 8)

r = [tex]\sqrt{(8-5)^2+(8-5)^2}[/tex]

  = [tex]\sqrt{3^2+3^2}[/tex]

   = [tex]\sqrt{9+9}[/tex]

   = [tex]\sqrt{18}[/tex] ⇒ r² = ([tex]\sqrt{18}[/tex] )² = 18

Then

(x - 5)² + (y - 5)² = 18 ← equation of circle

Answer: 56 m

Step-by-step explanation:

Given

The dimension of the garden is [tex]16\ m\times 12\ m[/tex]

So, the wire needed to fence around it is equal to the perimeter of the garden

[tex]\Rightarrow P=2(16+12)\\\Rightarrow P=2\times 28\\\Rightarrow P=56\ m[/tex]

Answer:

156000 [tex](1.12)^{t}[/tex]

156000 [tex](1+.12)^{t}[/tex]

those are both the same

Step-by-step explanation:

All the correct expressions that could be used to calculate the value of the house, in dollars, after t years is,

⇒ [tex]156,000 (1.12)^t[/tex]

Or, ⇒ [tex]156,000 (1 + 0.12)^t[/tex]

Mathematical expression is defined as the collection of the numbers and variables and functions by using operations like addition, subtraction, multiplication, and division is called mathematical expression.

We have to given that;

An investor paid $156,000 for a condominium in Texas in 2008.

And, The value of the homes in the neighborhood have been appreciating by about 12% annually.

Now,

We can formulate;

The value of the house, in dollars, after t years is,

⇒ Amount of house = P (1 + r%)ⁿ

⇒ Amount of house =  [tex]156,000 (1 + 0.12)^t[/tex]

⇒ Amount of house =  [tex]156,000 (1.12)^t[/tex]

Therefore, We get;

All the correct expressions that could be used to calculate the value of the house, in dollars, after t years is,

⇒ [tex]156,000 (1.12)^t[/tex]

⇒ [tex]156,000 (1 + 0.12)^t[/tex]

Answer:

sin θ = 22.62°

cos θ = 22.62°

tan θ = 22.62°

Step-by-step explanation:

From the diagram above

Opposite = 5

Adjacent = 12

Hypotenuse = 13

a) sin θ = Opp/Hypotenuse

sin θ = 5/13

sin θ = 0.3846153846

arc sin 0.3846153846

= 22.619864948°

Approximately = 22.62°

b) cos θ = Adjacent/ Hypotenuse

θ = 12/13

= arccos(0.9230769230769231)

22.619864948°

Approximately = 22.62°

c) tan θ = Opposite/Adjacent

θ = 5/12

= arctan(0.4166666666666667)

= 22.619864948°

= 22.62°

Answer:

72 degrees

Explanation:

From the diagram, angle on a straight line add up to 180 degrees.

180 degrees - 144 degrees = 36 degrees.

Sum of the angles in a triangle= 180 degrees

Angles x and the other are congruent(the marks from the diagram indicate).

Therefore sum of the congruent angles= 180 degrees - 36 degrees = 144 degrees

Angle x= 144/2= 72 degrees
