It should be [tex]15*10^{4}[/tex].

Step-by-step explanation:

[tex]300=3*10^{2}\\500=5*10^{2}\\\\300*500=(3*10^{2})*(5*10^{2})=(3*5)*10^{(2+2)}=15*10^{4}=1.5*10^{5}[/tex]

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

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

Answer:

m<A=117°

Step-by-step explanation:

Based on the given from the problem, we know that angle A and angle B are vertical angles

Vertical angles are congruent; they have the same value.

we know that the measure of angle A is (5x-3)° and the measure of angle B is (4x+21)°

since we know they are congruent via vertical angles theorem, we can make the two values equal to each other

5x-3=4x+21

add 3 to both sides

5x=4x+24

subtract 4x from both sides

x=24

we found the value of x. However, the question asks for the value of angle A, which is (5x-3)°

we substitute our known value to find the value of angle A

m<A= (5*24-3)°

m<A=(120-3)°

m<A=117°

the measure of angle A is 117°

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:

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:

FBG= 10*

ABC= 180*

Now I will uhhhhhhhhhhhhhhhhhhhhhhhhhhhh yeah

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

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

Step-by-step explanation:

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

Answer:

B

Step-by-step explanation:

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.)
