The gradient of the line joining R(-50, 460) and S(115, 55) is -2.45

The points on the line are given as

R = (-50, 460)

S = (115, 55)

The gradient of the line joining R(-50, 460) and S(115, 55) is calculated using

Gradient = (y2 - y1)/(x2 - x1)

This gives

Gradient = (460 - 55)/(-50 - 115)

Evaluate

Gradient = -2.45

Hence, the gradient of the line joining R(-50, 460) and S(115, 55) is -2.45

The value of x is 6 if E is the midpoint of the segment.

Given,

E is the midpoint, so DE = EF

DE = 3x

EF = 18

Since DE = EF,

3x = 18

x  =18/3

x = 6

If x = 6 , then

DE = 3x

DE = 3(6)

DE = 18

therefore, DE = EF since E is the mid point.

EF = 18

hence we get the value of x as 6.

Step-by-step explanation:

since both are square it is 12

Tim needs 40ft fencing.

For fencing the square garden we need to ascertain perimeter of the square.

Perimeter of plot = 2*(a+b)

Where a = length of the plot

b=width of plot

length =12ft

Since slopes m₁ and m₂ are equal to 5, it shows that these two lines are parallel.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + b

Given the following equations:

y = 5x + 1

2y - 10x + 3 = 0  ⇒ y = 5x - 3/2

m₁ = m₂ = 5.

The given expression is a fraction raised to a power and will be solved by multiplication of exponents for both numerator and denominator.

When in an expression, the base is a fraction raised to a number (exponent), the exponent is applied to both numerator and denominator.

In this case, the base is x^-2/3/y^-1/3 and the exponent is 15.

Since (x^a)^b=x^ab

Multiplication of exponent applied to both numerator and denominator,

(x^⁻²/₃/y^⁻¹/₃)^¹⁵=x^⁻²/₃*15/y^⁻¹/₃*15

Simplifying,

x^⁻²/₃*15/y^⁻¹/₃*15=x^-10/y^-5

Since both numerator and denominator have negative exponents, it is not yet in the simplest form.

According to negative exponents rule, x^-a=1/x^a

To remove the negative exponent, the fraction should be reversed.

Answer:   Slope = 2.250/2.000 = 1.125

 x-intercept = 40/9 = 4.44444

 y-intercept = 40/-8 = 5/-1 = -5.00000

Step-by-step explanation:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -5.000 and for x=2.000, the value of y is -2.750. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.750 - (-5.000) = 2.250 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

The amount invested in the bond with 5% simple interest is $16,666.67

The amount invested in the bond with 6.5% simple interest is $33,333.33  

What is simple interest?

The interest earned under a simple interest arrangement is determined as the amount invested multiplied by the interest rate and the time the investment lasts

I=PRT

let us assume that x was invested in the bond with 5%

interest on x=5%*x=0.05x

amount invested in other bond=50000-x

interest earned on 6.5%=(50000-x)*6.5%

interest earned on 6.5%=3250-0.065x

total interest=0.05x+3250-0.065x

total interest=3250-0.015x

total interest=3000

3000=3250-0.015x

0.015x=3250-3000

0.015x=250

x=250/0.015

x=$16,666.67

The time taken to reach $14200 in the bank with 4.25% interest compounded is 50 years

The time taken to reach 14200 with interest compounded semi-annually can be calculated by

[tex]A = P (1 +\frac{R}{100n})^{nT}[/tex]

where A is the total amount at the end of the period

          P is the principal amount

          R is the rate of interest

          n is the no. of interest compounded per year

          T is the time period

We know that A = 14200

                       P = 9000

                       R = 4.25%

                       n = 2

By substituting these values, we get

                    14200 = 9000 [1 + (4.25 /200[tex]]^{2T}[/tex]

                    14200/9000 =  [tex](1+0.02125)^{2T}[/tex]

                              1.5778 =  [tex](1+0.02125)^{2T}[/tex]

                          1.5778 =  [tex](1+0.02125)^{2T}[/tex]

                           1.5778  =[tex](1 +0.02125)^{2T}[/tex]

Taking logs on both sides,

                    log (1.5778) = log [tex](1+0.02125)^{2T}[/tex]

                    log (1.5778) = 2T log(1 +0.02125)

                              0.198 = 2T log(1.02125)

                             0.198 = 2T (0.00913)

                             0.918 = 0.01826 T

                                    T = 0.918 / 0.01826

                                    T = 50.27 yrs

Noun. preimage (plural preimages) (mathematics) For a given function, the set of all elements of the domain that are mapped into a given subset of the codomain; (formally) given a function ƒ : X → Y and a subset B ⊆ Y, the set ƒ−1(B) = {x ∈ X : ƒ(x) ∈ B}.

What is an Image?

The new position of a point, a line, a line segment, or a figure after a transformation is called its image.

Center of Dilation:

The center of a dilation is a fixed point in the plane about which all points are expanded or contracted. The center is the only invariant (not changing) point under a dilation (k ≠1), and may be located inside, outside, or on a figure.

The least integer greater than each number for log₅1/47 = -3

All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results.

Let y = log₅1/47

We know, logₐ x = y, only if a^y= x

Therefore, 5^y = 1/47

So, we must find an integer y such that 5 > 1/47

5^y > 1/47

5^{-3} > 1/47

(As, 5² = 25; 5³ = 125) (Since, 5² < 47, the answer will be 5³ as 5³ > 47)In this case, y = -3 will be the least integer to satisfy this inequality.

Therefore, the ultimate answer to the equation is log₅1/47 = -3

5 digit number

5abcd

a = 2 or a = 3. but a = 3 means the upper limit of 53,000. and the sum of digits is 8 and not 21.

so, a = 2.

d = 3n

c = b

5 + a + b + c + d = 21

5 + a + 2b + 3n = 21

a + 2b + 3n = 16

2 + 2b + 3n = 16

2b + 3n = 14

so, n must be an even number to allow an even result (14). therefore, n = 0 or n = 2 (any larger even number n like 4 would not create a single digit result)

if n = 0, then 2b = 14, b = 7

if n = 2, then 2b + 6 = 14, 2b = 8, b = 4

so, we have the options

Equation to find the mass of the rocket in terms of F and d is :

A force is the quantity that change the motion of the object. Force is that influence which can cause any object having some mass, to change it's position or to accelerate from it's original position.

Force (F) and mass (m) of any object are  directly proportional to each other. More the mass of the object , more the force will require to accelerate it.

Mathematically, we can write the equation of force as :

F = m . a

where , m = mass of the object

             a = constant value

In the statement given,

As, force of gravity varies directly with its mass

Therefore, F= k m , where k is a constant

Also force is inversely varies with square of distance d

Thus, F = k / d²

Combining both equations :
