Okay, so not sure what your question is, but this should help

X = 2

Y = 3

X = 8

Y=12

X = 8+2 = 10

Y = 12+3 = 15

15/10= 1.5

X = 1

Y = 1.5

Answer:x

y = [tex]\frac{x}{2}[/tex]+x

y=[tex]\frac{3}{2} x[/tex]

Answer:

Step-by-step explanation:

Let the starting point be B and the stopping be C as shown in the diagram below.

therefore, the angle at A will be (197-90)degree = 107degree

the angle at B is 45degree, since it is directly south west of C.

therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)

107+45+C=180

therefore, C=180-107-45=28degree

therefore, using sine rule gives;

sinA/a =sinC/c

sin107/a=sin28/4

0.9563/a=0.4695/4

0.9563/a=0.11736

therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

D because 2 has a x next to it so you divide by 2 on both sides

Answer:

60

Step-by-step explanation:

A Batman scored the following runs

58, 73, 21, 77, 99, 32

The mean can be calculated as follows

= 58+73+21+77+99+32/6

= 360/6

= 60

Hence the mean is 60

Answer: Choice A

f(1) = 2

f(n) = 2*f(n-1) for n ≥ 2

===========================================================

Explanation:

n = term number

So for instance, n = 3 represents the index for the 3rd term

We see that when n = 1, f(n) = 2 as shown by the left-most red point.

This means that f(1) = 2 which is a short way of saying "the first term is 2".

So the answer is between A and C.

Let's randomly guess that it might be choice C. We'll use the recursive rule given to generate the next term

f(n) = 4*f(n-1)

f(2) = 4*f(2-1) .... replace every n with 2

f(2) = 4*f(1)

f(2) = 4*2 ..... replace f(1) with 2, since f(1) = 2

f(2) = 8

This tells us that the 2nd term is 8, but the graph says it should be 4. Note the red point at (2,4)

Ultimately this all means that we can eliminate choice C and go with choice A as the final answer.

As a check, let's plug n = 2 into the recursive rule for choice A

f(n) = 2*f(n-1)

f(2) = 2*f(2-1)

f(2) = 2*f(1)

f(2) = 2*2

f(2) = 4

We get the proper second term. I'll let you check the other remaining terms. The notation 2*f(n-1) means "multiply 2 by the previous (n-1) term". In other words, the term values are doubling {2,4,8,16,...}

3a² + 13ab - 10b²

Step-by-step explanation:

(3a - 2b)(a + 5b)

Each term in each bracket multiplies each term in the other bracket.

3a(a + 5b) -2b(a + 5b)

3a² + 15ab - 2ab - 10b²

Okay so first you want to simplify the given equation  (7x+3y)(7x-3y)

in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2

Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2

The required equation of green and blue line is y = 3x- 4 and y = x+1

The standard equation of a line is expressed as y = mx + b

where;

m is the slope

b is the y-intercept

Note that the y-intercept is the point where the line cuts the y-axis

From the graph, the y-intercept of the green line is 3 while that of the blue is 1. This shows that the required equation of green and blue line is y = 3x- 4 and y = x+1

The angle of depression calculator. How to find the angle of depression?

Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:

Answer:

9:15 or 3:5

Step-by-step explanation:

A ratio can compare a part of a whole to a whole.

In this case, our whole is the total number of shots attempted: 15.

The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.

Put these values in a ration.

part:whole

9:15

Notice that 9 and 15 can be simplified by dividing both numbers by 3.

3:5

This is your simplified ratio.

Answer:

Part A is not a rt triangle

Part B is not a rt triangle

Part C is a rt triangle

Step-by-step explanation:

Part A:

290^2 + 696^2 = 750^2

84,100 + 484,416 = 562,500

Add the numbers on the left to see if the 2 sides are equal.

568,516 ≠ 562,500

Part B:

514^2 + 684^2 = 855^2

264,196 + 467,856 = 731,025

Add the numbers on the left to see if the 2 sides are equal.

732,052 ≠ 731,025

Part C:

450^2 + 1080^2 = 1170^2

202,500 + 1,166,400 = 1,368,900

1,368,900 = 1,368,900

Trinomial

The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

As per the given equation,

3x² - 3x + 1

To find the roots of the above quadratic equation,

3x² - 3x + 1 = 0

x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)

x = [3 ± √(-3)]/6

x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6

Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".

Answer: 1.5 x 10^5

Step-by-step explanation:

The first step is to re-arrange the factors like this :

5 x 3 x 10^2 x 10^2

Since

5 x 3 = 15

and the index law

10^a x 10^b = 10^a + ^b

gives us

10^2 x 10^2 = 10^2 + ^2 = 10^4

then we can rewrite the product like this :

5 x 3 x 10^2 x 10^2 = 15 x 10^4

Finally, we need to convert this into scientific notation :

15 x 10^4 = 1.5 x 10^5  

So the final answer is

1.5 x 10^5

Answer:

side length of 2

side length of 6

side length of 7

Step-by-step explanation:

So remember the two shorter lengths added together have to be greater than the longest side length

For the first answer choice we add 7 and 8

7+8=15

The two shorter sides added are not greater then the longest side so that is not the answer

For the second answer choice we add

8 and 5

8+5=13

13 is not greater than 14 so this is not the answer choice either

For the third one we add 6 and 3

6+3=9 which is not greater than 10 so this is not the answer

For the last one we add 2 and 6

2+6=8 which is greater than 7 so this one is the answer
