Isaac is going to invest in an account paying an interest rate of 6.3% compounded monthly. How much would Isaac need to invest, to the nearest ten dollars, for the value of the account to reach $57,000 in 7 years?

The value of c in the equation 7c - cy = 10x will give a line with slope +5 is -2.

We can rewrite the equation as:-

-cy = 10x - 7c

y = (-10/c) x + 7

Now the equation is in slope-intercept form which is given by:-

y = mx + b

Where,

m represents the slope of the line

b represents the y-intercept of the line

(x,y) represents ordered pair of each point of the line

Comparing both the equations, we get

m = -10/c

b = 7  

We have to get m = +5

Hence, equating both the values of m, we get

5 = -10/c

c = -10/5

c = -2

Hence, the value of c is -2.

Answer:

Step-by-step explanation:

J(x) = 3x^2 + 2x - 5

they have asked us to find J(3), therefore substitute x with 3 throughout the equation.

j(3) = 3*3^2 + 2*3 - 5

J(3) = 3*9 + 6 - 5

J(3) = 27 + 6 - 5
J(3) = 33 - 5 = 28

The rate at which the x-coordinate is changing is 3√3 units per second .

In the question ,

it is given that

the equation of the particle moving in the circular orbit is x²+y²=16

given the y coordinate decreases at 3units per second

So, dy/dt = -3.

to find the rate at which the x-coordinate is changing , we will differentiate the given equation.

Differentiating the equation  x²+y²=16 with respect to t , we get

d/dt(x²+y²) = d/dt(16)

2x(dx/dt) + 2y(dy/dt) = 0

2x(dx/dt) =  -2y(dy/dt)

Dividing both sides by 2 ,

we get ,

x(dx/dt) =  -y(dy/dt)

[tex]\frac{dx}{dt} =\frac{-y(\frac{dy}{dt}) }{x}[/tex]

As the particle is passing through the point (2,2√3) , So, the point will satisfy the equation.

Substituting the value of x=2 , y=2√3 and dy/dt= -3 ,

we get ,

dx/dt = ((-2√3)*(-3))/2

= (6√3)/2

= 3√3

Therefore , the rate at which the x-coordinate is changing is 3√3 units per second .

Rational fraction is a fraction where a and/or b are fractions and b is not equal to 0.

Any function that can be expressed mathematically as a rational fraction—an algebraic fraction in which both the numerator and the denominator are polynomials—is referred to as a rational function. The polynomials' coefficients don't have to be rational numbers; they can be found in any field K. Any function that can be expressed as a polynomial divided by a polynomial is said to be rational. The domain of a rational function is the set of all numbers except the zeros of the denominator since polynomials are defined everywhere.

Given Data

a_____________ is a fraction where a and/or b are fractions and b is not equal to 0.

It should be noted that a mean simply refers to the average set of numbers that are given.

This will be illustrated as thus:

The total number of rate of change animals from week 1 to week 4 will be:

= (73 - 62) + (78 - 73) + (86 - 78)

= 11 + 5 + 8.

The nth term in the Fibonacci series is printed at the conclusion of the program.

The values of interior angle is 63°,  46°,  71°

Angles inside a polygon are referred to as interior angles. A triangle, for instance, has three interior angles. Interior angles are sometimes defined as "angles enclosed in the interior region of two parallel lines when they are intersected by a transversal."

Put all the values equal to 180°,

=> (2x+5) + (x+17) + (3x-16) = 180°

Now, solve this equation and find x,

=> 6x + 22 - 16 = 180

=> 6x = 180 - 6

=> x = 174 / 6

=> x = 29°

Put x = 29° in the 2x + 5, x + 17, 3x - 16

2x + 15                |   x + 17          |   3x - 16      

2 * 29 + 15          |  29 + 17        |   3 * 29 - 16

63°                      |   46°             |   71°

Reflection and rotation preserve length , so the perimeter of ΔABC is equal to the perimeter of ΔXYZ. A possible set of values for AB, BC and AC is  7,9 and 10 units.

A rotation is a transformation that occurs when a figure is turned a preset number of degrees around a fixed point (referred to as the center of rotation).

The given figure is a triangle ABC such that it is transformed by a rotation of 90 °and reflection about y=-5.

The image thus formed will be congruent to the object and will have same sides and perimeter.

Hence the perimeter will be 26 units and the possible length of AB,BC and AC will be 7,9 and 10 units which is the only possible option as a triangle cannot have sides 2 , 14  and 10.(2+10<14)

The formula for q will be q = p*logm/(logK - logt)

Logarithm

A logarithm is defined as the power to which a number must be raised to get some other values. It is the most convenient way to express large numbers. A logarithm has various important properties that prove multiplication and division of logarithms can also be written in the form of logarithm of addition and subtraction.

Given equation:

[tex]K=tm^{(\frac{p}{q} )}[/tex]

We have to find a formula for q.

Raising the whole equation to the power of q, we get

[tex]K^q=t^qm^{p}[/tex]

We can rewrite it as,

[tex]\frac{K^q}{t^q}=m^p[/tex]

[tex](\frac{K}{t})^q=m^p[/tex]

Operating with logarithm on both sides, we get,

q*log(K/t) = p*logm

Answer:

4 outfits

Step-by-step explanation:

So to find out how much he has left after all his purchases to buy new biking outfits we can add:

9.54 x 3 = 28.62

22.01 + 28.62 + 322.09 = 372.72

Now we subtract his budget by how much he has already spent:

620 - 372.72 = 247.28

He has $247.28 left for outfits so we can divide 247.28 by $61.82 (the amount per outfit) to find how many he can buy:

247.28 / 61.82 = 4

Adrian can buy 4 outfits.

When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent. If two or more ratios have the same value when reduced to their most basic form, they are said to be equal. For instance, the ratios 1:2, 2:4, and 4:8 are identical. When reduced to their most basic form, all three ratios have the same value, or 1:2. We can multiply or divide the words by a natural number to get analogous ratios to a given ratio. When two words are co-prime (have just one other common factor), we multiply them by any natural number instead of performing the division procedure.
