The triangle below is isosceles.

Answer:

[tex]x^{3}[/tex]

Step-by-step explanation:

in powers:

when there is x to the power of 6 to the power of 6 as an example you should multiply 6x6=36

so in this one try to do it like the one up there

6*[tex]\frac{1}{2}[/tex]=3 so it is [tex]x^{3}[/tex]

The result of the given equation  [tex](3x^2 - 2^x + 5) -(x^2 + 3x - 2)\\[/tex] is [tex]4x^4-10x^3 + 14x^2[/tex]

"Cubic polynomial is a type of polynomial based on the degree i.e. the highest exponent of the variable. Hence, a cubic polynomial is a polynomial with the highest power of the variable or degree is 3. A polynomial is an algebraic expression with variables and constants with exponents as whole numbers"

"The general form of a cubic polynomial is p(x): ax3 + bx2 + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers. An equation involving a cubic polynomial is called a cubic equation. "

The given equation is given as[tex](3x^2 - 2^x + 5) - (x^2 + 3^x - 2)[/tex]

Solving it ,we get [tex]2x^2 - 5x +7[/tex]

Now multiplying it by [tex]1/2x^2[/tex] gives us [tex]4x^4-10x^3 + 14x^2[/tex]

Hence the answer is [tex]4x^4-10x^3 + 14x^2[/tex]

Answer:

Step-by-step explanation:

x + y = 7 + 2/8 = 58/8

x - y = 2 + 4/8 = 20/8

Add the equations together

2x = 78/8

x = 39/8

y = x - 20/8 = 19/8

x = 39/8 = 4⅞

y = 19/8 = 2⅜

Step-by-step explanation:

The triangle is an isosceles right triangle, and the true statements about the triangle are

The given parameters are:

Angle = 90 degrees

Two side lengths = 5 cm

Given that one of the angles is 90 degrees, then it means that the triangle is a right triangle.

Also since two sides are equal, then the triangle is an isosceles triangle, and the other angles are 45 degrees each

Hence, the true statements about the triangle are (a), (c) and (e)

Answer:

A11 = 230.66015625

Step-by-step explanation:

hi!

the first thing that you have to do when solving for the 11th term in a geometric sequence is to find the common ratio!

I did this by dividing 6/4 = 3/2 (I did multiply this by 6 to test if it was correct, and it was)

the next thing you can do is use this formula:

An = A1*r^(n-1)

An = the nth term of the sequence

A1 = the first term in the sequence

r = common ratio

n = the number of term that you are solving for

A11 = 4*(3/2)^(11-1)

A11 = 4*(3/2)^10

A11 = 230.66015625

Answer:

y = 7x

y = $133

Step-by-step explanation:

x = independent variable

y = dependent variable

y = 7x

Where,

y = total amount saved

x = number of weeks

7 = constant

When x = 19

y = 7x

y = 7 * 19

y = 133

y = $133

Answer:

Speed of sidekick : 600

Speed of superhero : 500

Step-by-step explanation:

x = sidekick speed

speed of hero = x-100

Time of hero = -36

1800/(x-100) = (1800/x) + 0.6

That equations solves to x = 600 and x = 500 or -500

The given difference in speed and the arrival time, as well as the

distance traveled, gives the speeds as 500 and 600 km/hr.

Response:

The given parameters are;

Superhero's speed = 1800 km

Speed of the superhero = Speed of the sidekick - 100 km/h

The time the superhero arrives at the hideout = 36 minutes after the sidekick = 0.6 hours

Required:

The speed of the superhero and the sidekick

Solution:

Let v represent the speed of the superhero, we have;

v × (t + 0.6) = (v + 100) × t

v·t + 0.6·v = v·t + 100·t = 1800

0.6·v = 100·t

[tex]t = \dfrac{0.6}{100} \cdot v[/tex]

Therefore;

0.006·v² + 0.6·v - 1800 = 0

Which gives;

v² + 100·v - 300,000 = 0

(v - 500)·(v + 600) = 0

v = 500, or v = -600

Answer:

$362.64

Step-by-step explanation:

Assuming that "S" represents the money in U.S. dollars, we are given the starting amount as 270 pounds.

We first need to convert the pounds into euros, since £1 = €1.11

So all we have to do is £270 × €1.11 = €299.70

Then, we need to convert euros into dollars, since €1 = $1.21

So all we have to do here is €299.70 × $1.21 = $362.637

Which rounds to $362.64

Answer:

m∠SBE = 26°,  [tex]m\hat O B[/tex] = 126°

Step-by-step explanation:

The arc of a circle is a portion of the circumference of the circle. For a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.

Central angle is an angle whose vertex is on the center of the circle and endpoints on the circumference of the circle. If the endpoints of the central angle are are also the endpoints for the angle's intercepted arc, then both angles are congruent.

Also, the angle at the center is twice the angle at the circumference.

Angle at center = [tex]m\hat S E[/tex] = 52° (central angle is congruent with angle that intercept the arc)

2 * m∠SBE = central angle (angle at the center is twice the angle at the circumference)

2 * m∠SBE = 52

m∠SBE = 26°

2 * m∠BEO = central angle (angle at the center is twice the angle at the circumference)

2 * 63 = central angle

central angle = 126°

Angle at center = [tex]m\hat O B[/tex] = 126° (central angle is congruent with angle that intercept the arc)

mean absolute deviation (MAD) for A

=[|5-3|+|5-4|+8|5-5|+|5-6|+|5-7|]/12=6/12=1/2

for class B

mean =4 hours given

mean absolute deviation (MAD) for B

=[|4-7|+|4-8|+8|4-9|+|4-10|+|4-11|]/12=60/12=5

Answer:

Step-by-step explanation:

we are given some data 3,4,5,5,5,5,5,5,5,5,6,7

we want to figure out the MAD (Mean absolute deviation) of the given database

remember that,

[tex] \rm\displaystyle \: MAD = \frac{1}{n} \sum_{i = 1} ^{n} |x_{i} - m(x)| [/tex]

where m(X) represents the mean of the given database and [tex]|x_{i}-m(X)|[/tex] tells us to subtract every data with the got mean and n represents the number of data

let figure out m(X)

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 5(8) + 6 + 7 }{12} [/tex]

simplify multiplication:

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 40 + 6 + 7 }{12} [/tex]

simplify addition:

[tex] \rm\displaystyle \: m(x) = \frac{60}{12} [/tex]

simplify substraction:

[tex] \rm\displaystyle \: m(x) = 5[/tex]

let's figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]

[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |3 - 5 | & 2 \\ \hline | 4 - 5 | &1 \\ \hline |5(8) - 5(8)| &0 \\ \hline |6 - 5|&1 \\ \hline |7 - 5| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]

last part let's figure out MAD
