Can some one help me with these two

Mathematics
1 answer:
kakasveta [241]3 years ago
5 0

Answer:

11. B

12. D

Step-by-step explanation:

11)

2 times 10⁻² = 2·0.01 = 0.02 ≈ 0.0201

12)

6·10⁻⁴ = 6·0.0001 = 0.0006

However, 0.00058 rounds to 0.0006 and 0.00067 rounds to 0.0007, so the answer is a better estimation for D than for B.

There is a line that includes the point (2, 10) and has a slope of 1. What is its equation in
rjkz [21]

Answer:

The line is y=1x+8

Step-by-step explanation:

We can use point-slope form of a line to make an equation. Point-slope form is as follows:

y-y₁=m(x-x₁)

**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.

1. Plug in the given info:

y-10=1(x-2)

2. Distribute the 1:

y-10=1x-2

3. Add 10 to both sides:

y=1x+8

Find the value of x. Round to the nearest degree.
Fantom [35]

Answer:

x = 51

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are going to use the appropriate trigonometric identity

We have the side facing the right angle ( hypotenuse) and the side facing the angle given (opposite)

The trigonometric identity that links both is the sine and it is the ratio of the opposite to the hypotenuse

Thus, we have it that;

sine x = 7/9

x = arisine (7/9)

x = 51
