what is 2(5+34-67/45*43)^2 equal to?

Answer:

A).

Step-by-step explanation:

The numbers should be in consecutive order e.g. - 6.2 6.3 6.4

The coordinates for point B are (a) (7,0)

Point B is located 7 units right of the origin. What are the coordinates for point b?

The origin is located as:

(0,0)

From the question, we understand that:

B ⇒ 7 unit right of origin

This means that:

B = (0 + 7, 0)

Evaluate the sum

B = (7,0)

Hence, the coordinates for point B are (a) (7,0)

Step-by-step explanation:

x² + y² = 64, because when x is 0, y = ± 8, when y is 0, x = ± 8, that is the radius r

The equation of a circle with center at the origin and radius 8 is,

⇒ x² + y² = 64

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

This circle is centered at the origin, and the length of its radius is 8.

Since, The equation of a circle with center at the origin and radius r is,

⇒ x² + y² = r.

Hence, for this circle, the equation would be;

⇒ x² + y² = 8²,

or simplified,

⇒ x² + y² = 64

Thus, The equation of a circle with center at the origin and radius 8 is,

Step-by-step explanation:

To find y-int, plug in 0 for x. This gives you the point 0, 14.

You can also use the quadratic equation to find the x-intercepts.

Answer:

see explanation

Step-by-step explanation:

A

given a parabola in standard form

f(x) = ax² + bx + c ( a ≠ 0 ) , then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = - 2x² - 4x + 14 ← is in standard form

with a = - 2, b = - 4 , then

x = - [tex]\frac{-4}{-4}[/tex] = - 1

substitute x = - 1 into f(x) for corresponding y- coordinate

f(- 1) = - 2(- 1)² - 4(- 1) + 14 = - 2 + 4 + 14 = 16

vertex = (- 1, 16 )

B

to find the y- intercept let x = 0

f(0) = - 2(0)² - 4(0) + 14 = 0 - 0 + 14

y- intercept = (0, 14 )

C

to find the x- intercepts let f(x) = 0 , that is

- 2x² - 4x + 14 = 0 ( divide through by - 2 )

x² + 2x - 7 = 0 ( add 7 to both sides )

x² + 2x = 7

using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 7 + 1

(x + 1)² = 8 ( take square root of both sides )

x + 1 = ± [tex]\sqrt{8}[/tex] ( subtract 1 from both sides )

x = - 1 ± [tex]\sqrt{8}[/tex]

then

x = - 1 - [tex]\sqrt{8}[/tex] ≈ - 3.83 ( to 2 dec. places )

x = - 1 + [tex]\sqrt{8}[/tex] ≈ 1.83 ( to 2 dec. places )

that is x- intercepts are (- 3.83, 0 ) , (1.83, 0 )

Using the cosine rule, the equation to use to solve for x is: x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41)) ≈ 3.1 cm.

The cosine rule is given as, c = √(a² + b² − 2ab × cos(C))

Answer: 7/8

What you have to do here is to find the highest number which can be divided by both. Or you have to divide both the numerator and denominator until it can not be divided by any number anymore. You can do this by finding the highest common factor (HCF) of both the number, 35 and 40.

Highest Common Factor: HCF of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.

So, the highest number which divides 35 and 40, is 5. Now 35 divided by 5 is 7 and 40 divided by 5 is 8. The final answer is 7/8 and there is no more numbers which can divide both of them by a specific number.

Based on the given mean absolute deviations, the sample mean absolute deviation will be 2 and the population mean absolute deviation will be 3.8.

= Sum of sample mean absolute deviation / Number

= (0 + 0.5 + 4.5 + 0.5 + 0 + 4 + 4.5 + 4 + 0) / 9

= 2

First find the population mean:

= (10 + 11 + 19) / 3

= 13.3

Population mean absolute deviation:
= 1/3 x ( (10 - 13.67) + (11 - 13.3) + (19 - 13.3))

= 3.8

We can therefore see that the sample mean deviations is a biased estimate of the population mean absolute deviation.
