What is the length of CD¯¯¯¯¯¯¯¯?

Mathematics
1 answer:
vladimir2022 [97]3 years ago
6 0

Answer:

23 units

Step-by-step explanation:

Since both lines are chords, they're equal in length. This means we can set them equal to each other.

2x + 2x +2 = 15 + 8

This becomes 4x + 2 = 23.

Subtract two from each side to get 4x = 21.

Now divide by 4 to isolate x.

This makes x = 5.25.

Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units

Diep bought a baguette loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his san
maxonik [38]
Given that the original length of the baguette is 65, and for each day 15 gets cut off, we have the function l(d) = 65 - 15d where d is a positive integer representing the nth day. As a matter of fact, the possible vaalues for d are 0, 1, 2, 3, and 4. Since on the 5th day, there won't be enough baguette anymore. This shows that the function l(d) is not continous since only certain points satisfy the condition. Thus, the function is l(d) = 65 - 15 where {d| 0 ≤ d ≤ 4} and it is discrete<span>.</span>

How do you factor x^2+11x+10=0?
xz_007 [3.2K]

Answer:

x = -1 or x = -10

Step-by-step explanation:

x^2 + 11x + 10 = 0

x^2 + 10x + x + 10 = 0

x(x + 10) + 1(x + 10) = 0

(x + 1) (x + 10) = 0

x + 1 = 0 or x + 10 = 0

x = -1 or x = -10

Ruby is visiting San Francisco. From her hotel she walks 4 blocks east and 2 blocks north to a coffee shop. Then she walks 5 blo
NeTakaya
I'm not sure if you have done vectors as of yet, but you would first add the x components and y components separately. 

x-components: 4 blocks + 5 block = 9 blocks 
y-component: 2 blocks + 1 block = 3 blocks

Magnitude of this: √(x₂-x₁)²+(y₂-y₁)² 
= √(9)²+(3)²
=√81+9 
=9.5 blocks approx

Angle of of the resultant vector; 

tanθ=y/x 
tanθ=3/9 
θ=tan⁻¹(3/9)
θ=18.43 degrees

Hope I helped :)
