Answer:

The three numbers are 29, 31, and 33.

Step-by-step explanation:

Let's imagine that the three consecutive odd integers are 2x−1, 2x+1, and 2x+3. And we are told the sum is 93 right? So, let's equal the three numbers to 93.

2x − 1 + 2x + 1 + 2x + 3 = 93

6x + 3 = 93

-3 -3

-----------------

6x = 90

/6 /6

----------------

x = 15

Now, plug in x into 2x−1, 2x+1, and 2x+3 to find the three numbers.

2x − 1 2x + 1 2x + 3

2(15) - 1 2(15) + 1 2(15) + 3

30 - 1 30 + 1 30 + 3

= 29 = 31 = 33

Evaluate the expression.

Gemiola [76]

Answer:

98 is the answer of the expression

Step-by-step explanation:

AS it is a simple algebraic expression so these are solved by BDMAS rule which means that we have to solve the brackets first starting from the smaller bracket first which is inside a larger bracket then we will move to Division then multiplication then addition and then subtraction

so the following equation can be written as

= $2^{3}[\frac{1}{4}+4(36/12)]$

First of all solving smallest bracket and division inside it

= $2^{3}[\frac{1}{4}+4(3)]$

Multplying 4 inside

= $2^{3}[\frac{1}{4}+12]$

Now solving the 2³

= $8[\frac{1}{4}+12]$

Now solving the expression inside the bracket by taking LCM

= $8[\frac{1 + 4*12}{4}]$

= $8[\frac{1 + 48}{4}]$

= $8[\frac{49}{4}]$

Now multiplying 8 with inside values

= $[\frac{8*49}{4}]$

AS 8 cuts out with 4 so

= 2 * 49

= 98

which is the answer of the expression

Convert the decimal expansion 0.1777 into a rational number

Helen [10]

Answer:

The rational form of the given number 0.1777 = $\frac{1777}{10,000}$

Step-by-step explanation:

The rational number is expressed as a number on the form of $(\frac{p}{q} ) , q \neq 0$

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

$\implies 0.1777 = \frac{01,777} {10,000} = \frac{1777}{10,000}$

Hence, the rational form of the given number 0.1777 = $\frac{1777}{10,000}$

Find an equation of the tangent line to the curve 2(x2+y2)2=25(x2−y2) (a lemniscate) at the point (−3,1). An equation of the tan

valina [46]

$2(x^2+y^2)^2=25(x^2-y^2)$

Let $y=y(x)$ , so that differentiating both sides wrt $x$ gives

$4(x^2+y^2)\left(2x+2y\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(2x-2y\dfrac{\mathrm dy}{\mathrm dx}\right)$

If $x=-3$ and $y=1$ , the above reduces to

$40\left(-6+2\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(-6-2\dfrac{\mathrm dy}{\mathrm dx}\right)\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac9{13}$

This is the slope of the tangent line, which has equation

$y-1=\dfrac9{13}(x+3)\implies\boxed{y=\dfrac{9x+40}{13}}$
