Answer:

x =(1-√-83)/6=(1-i√ 83 )/6= 0.1667-1.5184

x =(1+√-83)/6=(1+i√ 83 )/6= 0.1667+1.5184

Step-by-step explanation:

3x2-x+7=0  

Two solutions were found :

x =(1-√-83)/6=(1-i√ 83 )/6= 0.1667-1.5184i

x =(1+√-83)/6=(1+i√ 83 )/6= 0.1667+1.5184i

Answer:

P  140 units

A  1200 units^2

Step-by-step explanation:

The length of the rectangle is 20 to -20 = 20 - -20 = 40 units

The width of the rectangle is 20 to -10 = 20 - -10 = 30 units

The perimeter is given by

P = 2 ( l+w) = 2 (40+30) = 2 (70) = 140 units

The area is given by

A = lw = 40*30 = 1200 units^2

Answer:

The distance from the helicopter to the fire is 8909 feet.

Step-by-step explanation:

Refer the attached figure

The pilot of a helicopter sights a fire at an angle of depression of 11° i.e. [tex]\angle ACB = 11^{\circ}[/tex]

The helicopter's altitude is 1700 feet.i.e.AB = 1700 feet

We are supposed to find the distance from the helicopter to the fire i.e. AC

Using trigonometric ratios

[tex]Sin \theta = Perpendicular}{Hypotenuse}\\\\Sin 11^{\circ}=\frac{AB}{AC}\\\\Sin 11^{\circ}=\frac{1700}{AC}\\\\AC=\frac{1700}{Sin 11^{\circ}}\\\\AC=\frac{1700}{0.1908}\\\\AC=8909.85 feet[/tex]

Hence the distance from the helicopter to the fire is 8909 feet.

Answer:

Increasing both by the same amount of 2

Step-by-step explanation:

10 times 12=120,

and 11 times 13=143,

but 12 times 14 =168

An equation is formed of two equal expressions. The equation that can be used to find the value of x is x²+22x-168=0.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Millie has a rectangular pen for her dog that measures 10 ft wide by 12 ft long. Now, she needs to increase the area by 168 ft, that too by increasing the width and length by the same amount. Therefore, the equation can be written as,

[tex](10+x) \times (12+x) = (10 \times 12) + 168\\\\120 + 10x+ 12x +x ^2 = 120+168\\\\120 + 22x+x^2=120+168\\\\x^2+22x-168 = 0[/tex]

Hence, the equation that can be used to find the value of x is x²+22x-168=0.

Answer:

I believe this would be the correct answer. It has been a while since I have done a problem like this.

Answer:

x=1 & y=7

Step-by-step explanation:

y=7x.......(i)

y=-2x+9........(ii)

Solve for (ii) by replacing the value of y in (ii) with the value of y from (i)

y=-2x+9

7x=-2x+9

Add 2x on both sides,

7x+2x=-2x+9+2x

9x=9

Divide by 9 on both sides,

9x/9=9/9

x=1

Now,

Replace the value of x in eq (i)

y=7x

y=7×1

y=7

Therefore,the values of x and y are 1 and 7 respectively.

Answer:

-1/2

Step-by-step explanation:

The slope of the line is y=mx+b. when searching for the slope of a line you take where the line crosses EXACTLY on two points, for this grid it would be (0,3) and (2,2) based off this you see that you Rise 1 and Run 2. rise and run is how you find the formula for slope, since the line is going from the left side of the graph to the right (in a downward motion) the overall direction of the line is negative. now you plug in the answer to the formula given, y=-1/2x+3, the +3 or b in the formula is where the line intersects the y axis. this can be negative or positive. the slope can also be taken from the formula, -1/2for more explanation or questions ask please!

Option (2).It has a vertical translation by 2 units in the positive direction.

Step-by-step explanation:

Given question is not complete: find the  complete question with attachment

Errol's bike ride can be modeled by the equation,

[tex]d(t)=-\frac{1}{4}t+2[/tex]

Slope of the given equation = [tex]-\frac{1}{4}[/tex] which shows the rate of change of distance from Errol's house

Y-intercept = 2, shows the distance of the school from Errol's house

Let the equation that represents the distance of Daniel's home from the school is,

y = mt + b

Since speed of Daniel is equal to the speed of Errol, slopes of both the equations will be same.

Since y-intercept 'b' represents the distance from his home, b = 4

Now the equation will be,

[tex]d(t)=-\frac{1}{4}t+4[/tex]

Therefore, the graph representing the Daniel's equation will have a vertical translation by 2 units in the positive direction.

Step-by-step explanation:

14+6 is 16. Add 88 to 16 and you get 104. 200-104=96.

The two-frequency table that correctly shows the marginal frequencies of the given data is: B.

In a two-way frequency table, the marginal frequency is simply the the sum of any one of the columns or rows in a data.

In table B, 14 + 6 equals 16, so also does 88 + 16 = 104. Subtract 104 from 200, and you have 96.

Therefore, table B correctly shows the marginal frequencies.

Answer: The solution is (4,99) which means for in 4 months the total cost of each health club will be the same.

Step-by-step explanation:

Club A can be represented by the equation    y = 23x + 7  where x is the number of months  and y is the cost.

Club B can be represented by the equation   y = 16x + 35  where x is the number of months and y is the cost.

23x + 7 = 16x + 35     set the equation equal each other to solve for x

        -7               -7

23x  = 16x + 28

-16x     -16x

7x= 28

x= 4   now we know the value of  x is 4 so we will put it into the equation and solve for y

y= 16(4) + 35

Answer:

Domain: -4 < x < 4

Zeros: (-2, 0), (0, 0) and (2, 0)

The function is positive if: 0 < x < 2

The function is negative if: -4 < x < 0 and 2 < x < 4

Step-by-step explanation:

Domain of the function are those x values where the function is defined, For this case, -4 < x < 4

Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)

The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)

The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)

Answer:

18 degrees

Step-by-step explanation:

Since the measure of PQR is 90 degrees, the two angles contained in it must add up to 90 degrees. Therefore:

19+2x+35=90

Combine like terms:

2x+54=90

Subtract 54 from both sides:

2x=36

Divide both sides by 2:

x=18

Hope this helps!

Answer:

Step-by-step explanation:

Given an isosceles triangle of ABC where angle A is x°, angle B is 118°, angle C is x°. To get the measure of angle A, the following steps must be followed.

Sum of angle in a triangle is 180° as shown

∠A+∠B+∠C = 180°

∠A = 180°-(∠B+∠C)

Substituting the values of each angle in the expression to get ∠A we have;

∠A = 180°- (118°+x°)

Since ∠A = x

x = 180°- (118°+x°)

x = 180°-118°-x°

x+x°+118° = 180° (This gives the required equation)

To get x;

2x° + 118° = 180°

Subtracting 118° from both sides

2x° + 118°-118° = 180°-118°

2x°= 62°

x = 31°

Answer:

B: x + x + 118 = 180
