387.869911589 to 3 decimal places is 387.870.

A decimal is a number that is made up of integers and non-integers. The integers are separated from the non-integers by a decimal point.

In order to round off a number to 3 decimal places, there must be 2 numbers to the right of the decimal point.

In order to round off a number to 3 decimal places, if the ten thousandth figure is equal to five or greater than 5, one is added to the thousandth figure. If the ten thousandth figure is less than 5, there is no change in the thousandth digit.

The ten thousandth is greater than 9, so one is added to the thousandth digit. The number becomes 387. 870

By  Side - Angle - Side congruency (SAS) rule, ΔDFC is congruent to ΔAEB as shown below.

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.

Given is a geometrical diagram as shown in the image.

We can prove ΔDFC ≅ ΔAEB as follows -

AE = CF       [Given]

Add length EF on both sides of the equation, we get

AE = CF                                   ...[1]

∠ 1 = ∠ 2             [Given]                  ...[2]

Given is ∠ 1 = ∠ 2. Than the tangent of both angles will be same. On solving the tangent ratio, we get -

BE = FD                  ...[3]

From equation 1, 2 and 3, we can say that

ΔDFC ≅ ΔAEB

Therefore, by Side - Angle - Side congruency (SAS) rule, ΔDFC is congruent to ΔAEB.

In the picture, the polynomial equation is (3x-k)²

We have to find the k value and p value if (3x-k)²=9x²+px+16

Polynomial means polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable). The expression is divided into three categories: monomial, binomial, and trinomial depending on how many terms are included in it.

We get,

(3x-k)²=9x²+px+16

9x²-6xk+k²=9x²+px+16

We get,

p=-6k and k²=16

The next term would be 3 then 1 in the sequence 243, 81, 27, 9,... by the term of sequence and series through mathematical sequencing.

A grouping of numbers in a kind of a specific order is known as a sequence. On the other hand, a series can also be described as the accumulation of a kind of a sequence’s constituent parts.

Basically, the sequence proceeds with a dividing term of 3. The sequence will go on with the square root of the previous number. Basically, from backward, the sequence is an exponential multiple of 3.

Mathematical sequence and series formulas pertain to several kinds of sequences and series. A series is the accumulation of elements in a sequence, which is a group of arranged elements that follow a pattern.

The formulas for the nth term and the sum are typically included in the sequence and series formulas.

The form:

y = a(x-h)^2 + k

Is the vertex form of the quadratic equation, by finding the vertex, we conclude that k = -1.

For any quadratic equation of the form:

y = a*x^2 + b*x + c

With a vertex (h, k), we can rewrite the equation as:

y = a*(x - h)^2 + k

And the value h of the vertex is given by:

h = -b/(2a)

In this case, the quadratic equation is:

y = 2x^2 - 8x + 7

Then the value h of the vertex is:

h = -(-8)/(2*2) = 2

Evaluating the quadratic equation in x = 2 we will get the value of k, so we have.

y = 2*(2)^2 - 8*2 + 7 = -1

Then the vertex is (2, -1), which means that the value of K is -1.

Duval Street between latitudes (3,1) and (7,5). Val resides between coordinates (2, 15) and (-6, 3). Braxton Lane and Duval Street are not parallel or perpendicular.

Given that,

Mary resides on Duval Street between latitudes (3,1) and (7,5). On Braxton Lane, Val resides between coordinates (2, 15) and (-6, 3).

We have to find is Braxton Lane and Duval Street parallel or perpendicular.

To find the lines are parallel or perpendicular we have to find the slope of those points.

If slopes are equal then the lines are parallel.

If slopes are negative reciprocal then the lines are perpendicular.

We find the slope of Mary resides on Duval Street between latitudes (3,1) and (7,5).

m₁=[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

m₁=[tex]\frac{5 -1 }{7-3 }[/tex]

m₁=4/4

m₁=1

The slope of the Mary resides on Duval Street between latitudes (3,1) and (7,5) is 1.

We find the slope of Braxton Lane, Val resides between coordinates (2, 15) and (-6, 3).

m₂=[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

m₂=[tex]\frac{3 -15 }{-6-2 }[/tex]

m₂=-12/-8

m₂=3/2

The slope of the Braxton Lane, Val resides between coordinates (2, 15) and (-6, 3) is 3/2.

Answer:

X=17/24

Step-by-step explanation:

first you need to find common denominators. To find it, you would multiply the denominator of the 1 2/3 and the 2 3/8.8*3=24, which means the denominator is 24. For 1 2/3, we multiplied 3*8 so we also have to do it for 2. The new equation is x+1 16/24=2 3/8. But remember, we still have to multiply 8*3, which means we have to multiply 3*3 too.

New equation:x+1 16/24=2 9/24

Now we can subtract 1 16/24 from each side

X=17/24
