What method would be best to solve this equation

0.4x^2=3.5x

-Quadratic formula

-Factoring

-Completing the square

Answer:

A

Step-by-step explanation:

Given the graph of f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here g(x) is the graph of f(x) shifted 3 units to the left, then

g(x) = (x + 3)² → A

Answer:

A

Answer:

Step-by-step explanation:

Domain of a function is defined by the set of x-values (input values) and Range is the set of y-values (output values) of the function.

1). The range and domain of P = {(x, y)| y = 3}

Domain: Set of all real numbers

Range: {y: y=3}

2). The domain set of C = {(2, 5), (2, 6), (2, 7)}

 Domain: {2}

3). The range set of E = {(3, 3), (4, 4), (5, 5), (6, 6)}

  Range: {3, 4, 5, 6}

4). The range and domain set of F = {(x, y)| x + y = 10}

   Domain = Range = {All real numbers}

Answer:

[tex]48\pi\\\approx 150.796[/tex]

Step-by-step explanation:

1.Approach

To solve this problem, find the area of the larger circle, and the area of the smaller circle. Then subtract the area of the smaller circle from the larger circle to find the area of the shaded region.

2.Find the area of the larger circle

The formula to find the area of a circle is the following,

[tex]A=(\pi)(r^2)[/tex]

Where (r) is the radius, the distance from the center of the circle to the circumference, the outer edge of the circle. ([tex]\pi[/tex]) represents the numerical constant (3.1415...). One is given that the radius of (8), substitute this into the formula and solve for the area,

[tex]A_l=(\pi)(r^2)\\A_l=(\pi)(8^2)\\A_l=(\pi)(64)[/tex]

3.Find the area of the smaller circle

To find the area of the smaller circle, one must use a very similar technique. One is given the diameter, the distance from one end to the opposite end of a circle. Divide this by two to find the radius of the circle.

8 ÷2 = 4

Radius = 4

Substitute into the formula,

[tex]A_s=(\pi)(r^2)\\A_s=(\pi)(4^2)\\A_s=(\pi)(16)[/tex]

4.Find the area of the shaded region

Subtract the area of the smaller circle from the area of the larger circle.

[tex]A_l-A_s\\=64\pi - 16\pi\\=48\pi[/tex]

[tex]\approx150.796[/tex]

Answer:

m∠B = 111º

Step-by-step explanation:

use law of cosines

c² = a² + b² - 2ab*cosC

---------------------------------

15² = 7² + 11² - 2(7)(11)cosB

225 = 49 + 121 - 154cosB

225 = 170 - 154cosB

Subtract 170 form both sides

55 = -154cosB

Divide both sides by -154

-0.3571428571 = cosB

m∠B = arccos -0.3571428571

use calculator

m∠B = 110.924832425009406

Rounded

m∠B = 111º

Answer:

Hello there, lol.

Adjacent = Opposite/ Tan(35)

Adjacent = 4.3

Answer:

4.28

Step-by-step explanation:

basically using the sine ratios :

a/sinA = b/sinB = c/sinC

so, let's call the known side a (3) and its opposing angle A (35 degrees).

and we know C is 90 degrees.

sin(90) = 1

b = the missing side AC.

and because the sum of all angles in a triangle is always 180 degrees, the missing angle B is

B = 180 - 90 - 35 = 55

AC/sin(55) = 3/sin(35)

AC = b = sin(55) × 3/sin(35) = 4.28

a little more practice and calculate also c that way :

3/sin(35) = c/1

c = 3/sin(35) = 5.23

Answer:

A. 71% (±18%)

Step-by-step explanation:

Based on the confidence interval relation :

Mean ± Margin of error

The mean could be any given value :

However, the margin of error at a given confis nce level will will affected by the sample size, larger sample sizes will result in smaller margin of error values as the it will result in a large value denominator hence giving a small margin if error value when divided.

Margin of Error = Zcritical * σ/√n

Since.weve been told that the sample size is small, this will result in a large error margin value, from the options given, the value with the largest error margin value will be produced by the smallest samole size. Hence the option with the largest error margin value is ; ±18%

There's a trick to solve these graph questions

Solve the given quadratic equations in the options , the points which match with the changed graph will be the final option

if you solve the first option F(x) = x2-2

you'll get x = +2 and -2

as you can see , the Fx graph cuts the x axis at +2 and -2 and thus option A is correct

Step-by-step explanation:

since she got her first email in 9 days and got her second email 14 days later, and it continues to appear every 14 days.

so I think it must be 14n + 9

Answer:

x = 139

Step-by-step explanation:

The angles are alternate exterior angles , and when the lines are parallel, alternate exterior angles are equal

146

Step-by-step explanation:

4×12+5×10+4×12=146

Answer:

Option 2

Step-by-step explanation:

Minimum value is going to be in the y part of our coordinate, so we can just look there. I went ahead and used a graphing calculator to make things easy.

Starting off with option 2, we can see the minimum is -10. And in option 4 we can see the smallest y value is -6.

Using a graphing calculator (I used desmos), we can graph these other functions and figure out their minimums.

Option 1's y minimum is -7, and Option 3's y minimum is -2.25.

Option 1: -7

Option 2: -10

Option 3: -2.25

Option 4: -6

The questions asks for the smallest minimum value, which in this case is option 2.

Answer: The measurement of angle DBC is 65 degrees

Step-by-step explanation:

Line BD splits ABC into two angles ABD and DBC.

If ABC is 90 then the measures of ABD + DBC will be 90. Since we know the measure of ABD we can make this equation and solve it

[tex]90=25+x\\90-25=25+x-25\\65=x[/tex]

Answer:

85°

Step-by-step explanation:

the two lines that have red arrows on them are parallel and are cut by a transversal so angle 6 and the 95° angle are same side interior angles so they are supplementary angles so they need to add to 180°

∡ 6 = 180-95 = 85°

Answer:

i think its C if i may be correct

Answer:

true

Step-by-step explanation:

It is True that in a table of a proportional relationship, the ratio or y/x is constant.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that, y∝x

In order to eradicate the proportional sign introduces the constant as,

y=kx

k=y/x

k is the constant value.

Thus, it is True that in a table of a proportional relationship, the ratio or y/x is constant.

Answer:

15 players on each team

Step-by-step explanation:

- 2 players from EACH team is subtracted= 2(players)x6(teams) = 12 players in total off the field

- now there are only 78 players on the field

(78+12)/6= 15

-Adding the amount of players on the feild and the players that were sent for equitment is 90. Then dividing 90 by the amount of teams there are, 6

Answer:

[tex] \frac{AQ + 15}{AQ} = \frac{10 + 6}{6 } \\ 6AQ + 90 = 10AQ + 6AQ \\ 10AQ = 90 \\ AQ = 9[/tex]

Answer:

AQ = 9

Step-by-step explanation:

Given a line parallel to the side of a triangle and intersecting the other 2 sides then it divides those sides proportionally , that is

[tex]\frac{6}{10}[/tex] = [tex]\frac{AQ}{15}[/tex] ( cross- multiply )

10 AQ = 90 ( divide both sides by 10 )

AQ = 9
