Mathematics
1 answer:
LuckyWell [14K]3 years ago
0 0

Answer:

  • FB=6 Units
  • OE= 8 Units

Step-by-step explanation:

Theorem: A line drawn from the center perpendicular to the chord bisects the chord.

By the Theorem above, Point E and F bisects CD and AB into 6 Units each as seen in the diagram.

Therefore:

|FB|=6 Units

In Right Triangle OED, applying Pythagoras Theorem

10^2=6^2+|OE|^2\\|OE|^2=100-36\\|OE|^2=64\\|OE|^2=8^2\\|OE|=8 \:Units

Therefore:

  • FB=6 Units
  • OE= 8 Units

What is the sum of 2x^2 and 2x^3
jeyben [28]

For this case we have the following expression:

2x ^ 2 + 2x ^ 3

The terms are not similar, so they cannot be added.

<em>Examples of similar terms:</em>

x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4

Then, the expression given can only be rewritten as:

2 (x ^ 2 + x ^ 3)

This is taking common factor 2 to both terms.

Answer:

2 (x ^ 2 + x ^ 3)

Law of sines?? side c=22 side a=16 side b= 21 solve for angle c??? help
den301095 [7]

Answer:

Angle C measures:  71.52^o

Step-by-step explanation:

When you know the length of the three sides of the triangle and not a single angle, the law of sines is of no use. You need to use the law of cosines. In your case, since you want to find angle "C", you use the following;

c^2=a^2+b^2-2\,a\,b\,cos(C)\\2\,a\,b\,cos(C)=a^2+b^2-c^2\\cos(C)=\frac{a^2+b^2-c^2}{2\,a\,b} \\cos(C)=\frac{16^2+21^2-22^2}{2\,(16)\,(21)}\\cos(C)=0.3169643\\C=arccos(0.3169643)\\C=71.52^o

The larger of two numbers is 7 more than the smaller.Their sum is 29
mina [271]

Answer:

11 and 18

Step-by-step explanation:

if the smaller number is a

the larger number is a+7

their sum a + (a+7) = 29

2a + 7 = 29

2a = 29-7

2a = 22

a = 22/2

a = 11

the smaller number is 11

the larger number is 11 + 7 = 18
