Answer: y = 5x + 70

Step-by-step explanation:

In a triangle ABC, angle B=90, angle C=60, angle A=30 and BC=12cm. The area of the triangle is 144 * (√3/2) sq cm

In a right triangle with a 90 degree angle, the length of the side opposite the 90 degree angle is the height, and the length of the other two sides form the base. If angle C = 60 degrees, then angle A = 90 - 60 = 30 degrees.

If BC = 12 cm, then the height AC is equal to AB * sin(30) = 12 * (√3/2).

The area of the triangle is equal to (1/2) * base * height = (1/2) * 12 * (12 * (√3/2)) = (12 * 12 * (√3/2))/2 = 144 * (√3/2) sq cm

Step-by-step explanation:

The slope of a line represents the rate of change between two variables. In the case of Superior Segway Tours, the cost of the tour is changing as the number of hours for the tour changes. The rate of change can be calculated by dividing the change in the dependent variable (cost) by the change in the independent variable (hours). In this case, the slope is $28 per hour. This means that for every hour that is added to the tour, the cost will increase by $28.

The slope of this situation can be represented as the change in cost (y-axis) per unit change in time (x-axis). The slope in this case would be $28 per hour.

Answer:

Slope-intercept form is

Using basic arithmetic operations, the missing terms are a)  7/5 and b) 19/14.

There are four basic arithmetic operations which are addition, subtraction, multiplication, and division. These operations can be applied to whole numbers and fractions.

a) 14/16  x  8/7= y x  5/7

In order to solve for y, the numerator and denominator on LHS are simplified and multiplied:

14/16  x  8/7=  7/8  x  8/7 = (7 x 8)/(8 x 7)

As there are same numbers in both numerator and denominator, they are cancelled:

(7 x 8)/(8 x 7)=1

Hence,

1= y x  5/7

Multiply both side by 7/5

7/5  x 1= y x  5/7  x  7/5

y=  7/5

b) 1/2+  4/7= y -2/7

In order to solve for y, add the fraction on LHS:

1/2+  4/7=  ((7 x 1)+(4 x 2))/((2 x 7)) = (7+8)/14=15/14

Hence,

15/14= y -2/7

Add 2/7 to both sides:

15/14+  2/7= y -2/7  +  2/7

y = (15+4)/14=19/14

Assuming that interest for a given month is based on the balance for the previous month, it will take 6 months to pay off the credit card debt of $1,200 when making a net payment of $225.

An online finance calculator can determine the period for a compound interest system.

The length of payment uses the beginning credit card balance of $1,200 and the net payment of $225 (since a monthly payment of $300 is made when an additional charge of $75 is withdrawn from the card).

I/Y (Interest per year) = 18%

PV (Present Value) = $1,200

PMT (Periodic Payment) = $-225 ($300 - $75)

FV (Future Value) = $0

Results:

Period (N #) = 5.6

Sum of all periodic payments = $-1,260.08

Total Interest = $60.08

Thus, within six months you can pay off the credit card debt.

The projection of vector v on u is =[tex]\=109/\sqrt{113}(2i+10j+3k)[/tex]

Sometimes the inner product and the dot product are considered to be the same. The formal definitions of projection and rejection employ the inner product rather than the dot product whenever they don't coincide. The concepts of projecting a vector onto another and rejecting a vector from another can be applied to the concepts of projecting a vector onto a plane and rejecting a vector from a plane for a three-dimensional inner product space.

A vector's orthogonal projection on a plane is the vector's projection on that plane. A vector is rejected from a plane when it is projected in an orthogonal direction on a straight line. They're both vectors. The first is orthogonal to the plane, while the second is parallel.

we have v=10i+8j+3k and u=2i+10j+3k,

The possible values of two consecutive even integers, of which the sum of their squares is 1684, are 28 and 30 for positive integers, while for negative integers, they are  -28 and -30.

The difference between two consecutive even integers is 2.

Let the integers be a and (a+2). Then,

a² + (a + 2)² = 1684

a² + a² + 4a + 4 = 1684

2a² + 4a - 1680 = 0

a² + 2a -840 = 0

Hence, we get a quadratic equation.

There are three methods of solving a quadratic equations: by factoring, completing the square, and by using the abc formula.

Use the factoring method:

a² + 2a -840 = (a - 28) (a + 30)

a = 28  and a = -30

Hence, if the integers are positive, they are: 28 and 30.

Answer:

x = 67.5 degrees

Step-by-step explanation:

this is an octagon which has 8 sides

the sum of all interior angles can be found by taking the number of sides, reducing it by 2, and then multiplying by 180

(8-2)*180 = 6(180) = 1080

the 1080° must be split equally among all 8 angles because it is a 'regular' polygon

1080/8 = 135

however, 'x' represents half of each regular angle so it is 67.5 degrees

Answer:

7^3

Step-by-step explanation:

since seven is being multiplied by itself 3 times, it is being cubed. So it needs to be raised to the third power.

hope this helps!!! :3

Answer: (-7)(-7)(-7) is equal to -7^3 (just imagine that the three is on the top right outer corner of the 7)

Step-by-step explanation:

A power is when you multiply a number by itself a certain number of times, in this case, we are multiplying the number 7 by itself 3 times. Every time it is multiplied by its self, the power of that number goes up (if you are using a power of one for any number, it will stay the same). Here is an example:

-7 to the first power is just -7.

-7 to the second power, or squared is just (-7)(-7) or (-7) x (-7).

-7 to the third power, or cubed, is just (-7)(-7)(-7) or (-7) x (-7) x (-7).

The inverse of the function is f⁻¹ ( x ) = ( x + 5 )² and the domain is x ≥ 0

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is given as

f ( x ) = √x - 5   be equation (1)

On simplifying the equation , we get

y = √x - 5

To calculate the inverse of the function , solve for x , we get

Adding 5 on both sides of the equation , we get

√x = y + 5

Taking the square on both side of the equation , we get

x = ( y + 5 )²

Substitute the value of x = f⁻¹ ( x ) and y = x , we get

f⁻¹ ( x ) = ( x + 5 )²

And , the domain of the function is [ 0 , ∝ ]

The period for which the force acts on the body is  0.6 seconds.

Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum.

Given the force applied is 4600 N

F = 4600 N

and change in momentum = Δm = 2760 kg m/s

force is given by a change in momentum to the change in time

F = Δm/Δt

Δt = Δm/F

Δt = 2760/4600

Δt = 0.6 seconds

The nature of the roots of a quadratic equation depends on the value of the discriminant, which is given by b^2 - 4ac, where a, b, and c are coefficients in the equation ax^2 + bx + c = 0. If the discriminant is positive, the roots of the equation will be real and distinct, and their sign will depend on the sign of the coefficients a, b, and c. If p, q, and r are positive, the value of the discriminant (q^2 - 4pr) will be positive, and the roots of the equation px^2 + qx + r = 0 will be real and distinct, but their sign cannot be determined just based on the values of p, q, and r alone.

 A perpendicular bisector is a line segment, ray, or line that goes through the middle of a given line segment and crosses it at a 90° angle.

A line, ray, or line segment is a perpendicular bisector if it divides another line segment in half proportionately and makes a right angle (90o) with it at its halfway.

In other words, the perpendicular bisector serves as both a perpendicular line to the line segment and a bisector, cutting it in half.

The intersection of the perpendicular bisector with the line segment represents its midpoint.

Given that point T is the center of dilation, we know that the length of line segments TX' and TY' are proportional to the length of line segments TX and TY, respectively.

We can express this as:

TX' = k * TX

TY' = k * TY

where k is the scale factor.

We are given the lengths of TX' and TY':

TX' = 6

TY' = 9

So, we can solve for k:

9 / k = 6

k = 9 / 6 = 3 / 2

Now that we know the value of k, we can find TY:

TY = TY' / k = 9 / (3 / 2) = 6 * (3 / 2) = 9

Next, we are given the length of XX':

XX' = 2

And using the dilation formula, we can find XX:

XX = XX' / k = 2 / (3 / 2) = 2 * (2 / 3)

Finally, we can find TX by using the Pythagorean theorem:

TX^2 = TY^2 + XX^2

TX^2 = 9^2 + (2 * (2 / 3))^2

TX^2 = 81 + (4 / 3)^2

TX^2 = 81 + 16 / 9

TX^2 = 81 + 16 / 9

TX = √(81 + 16 / 9) = √(81 + 16 * 9 / 9) = √(81 + 16) = √97

So, TY = 9 and TX = √97. Therefore, YT = TY - TY' = 9 - 9 = 0.

Now that we know the value of k, we can find TY:

TY = TY' / k = 9 / (3 / 2) = 6 * (3 / 2) = 9

XX' = 2

XX = XX' / k = 2 / (3 / 2) = 2 * (2 / 3)

TX^2 = TY^2 + XX^2

TX^2 = 9^2 + (2 * (2 / 3))^2

TX^2 = 81 + (4 / 3)^2

TX^2 = 81 + 16 / 9

TX^2 = 81 + 16 / 9

TX = √(81 + 16 / 9) = √(81 + 16 * 9 / 9) = √(81 + 16) = √97
