Answer:

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ BCD is an exterior angle of the triangle, thus

∠ BCD = 50° + 60 = 110° → D

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent

Serjik [45]

Answer:

Option (1)

Step-by-step explanation:

By the property of alternate segment theorem,

"Angle formed between the tangent and the chord in a circle measures the half of the measure of the intercepted arc"

m(∠EFG) = $\frac{1}{2}$ × m(minor arc FG)

minor arc FG = 2m(∠EFG)

= 2(76°)

= 152°

Therefore, Option (1) will be the correct option.

Solve this step by step using the quadratic function y=x^2 +x+2

Ne4ueva [31]

Answer:

x=+ $\frac{\sqrt{4y-7}-1 }{2}$

Step-by-step explanation:

Quadratic function =( -b+ $\sqrt{b^2+4ac}$ )/2a

x^2+x+2-y=0

x=-1+ $\sqrt{1^2-4(2-y)}$ /2

x=-1+ $\sqrt{4y-7}$ /2

x=+ $\frac{\sqrt{4y-7}-1 }{2}$

Pretty sure this is right. Would appreciate a brainliest

A card game has 50 cards. After dealing 7 cards to each player, Tupi has 15 cards left over. Solve the equation 50 7p = 15 to fi

mafiozo [28]

Answer:

50 - 7p = 15....subtract 50 from both sides

-7p = 15 - 50

-7p = - 35...divide both sides by -7

p = -35/-7

p = 5 <=== there are 5 players

(A) find F(x) for the indicated values of x, if possible

dem82 [27]

Answer:

A) The indicated values of F(x) for x=-3 and x=5 are $F(-3)=-27$ and $F(5)=125$

B) The domain of f is the set of all real numbers

Step-by-step explanation:

Given that the function F is defined by

$F(x)=x^3$ for x=-3,5

A) To find F(x) for the indicated values of x :

Given $F(x)=x^3$ for x=-3,5

Put x=-3 in the given function

$F(-3)=(-3)^3$

$=(-3)\times (-3)\times (-3)$

$=-27$

Therefore $F(-3)=-27$

Put x=5 in the given function

$F(5)=(5)^3$

$=(5)\times (5)\times (5)$

$=125$

Therefore $F(5)=125$

The indicated values of F(x) for x=-3 and x=5 are $F(-3)=-27$ and $F(5)=125$

B) To find the domain of f :

The domain of the f in the given expression is the set of all real numbers except where the expression $x^3$ is undefined. In this case, there is no real number that makes the expression undefined.

The domain of f is the set of all real numbers
