4/5 = 8/10

so... no they are not equivalent

Answer:

h(x) = 1/4 x - 2

Step-by-step explanation:

f(x) = 4x + 8

y = 4x + 8

x = 4y + 8

4y = x - 8

y = 1/4 x - 2

h(x) = 1/4 x - 2

HELP ASAP,, WILL GIVE BRAINLIEST

madreJ [45]

Answer:

a = 50°, b = 130°, c = 20°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the right triangle

a + 40° + 90° = 180°

a + 130° = 180° ( subtract 130° from both sides )

a = 50°

a and b are adjacent angles and sum to 180° , so

a + b = 180°

50° + b = 180° ( subtract 50° from both sides )

b = 130°

Then sum the angles in the top triangle, that is

30° + 130° + c = 180°

160° + c = 180° ( subtract 160° from both sides )

c = 20°

The dot product can be used to determine the square of the magnitude of a vector v. Which of the following expressions represent

konstantin123 [22]

Answer:

c) v.v

Step-by-step explanation:

The Dot product also known as scalar product or inner product is the multiplication of two equal length vectors which results in a scalar.

Mathematically,

$a.b=|a|*|b|*cos(\alpha)$

where $|a|$ and $|b|$ are the magnitudes of the vectors a and b

$cos(\alpha)$ is the angle between vectors a and b

If a and b are in the same direction then $cos(\alpha)=1$

$a.b=|a|*|b|$

if a and b are orthogonal (90°) then $cos(\alpha)=0$

$a.b=0$

To represent the square of the magnitude of a vector v

$v.v=|v|*|v|=|v|^2$

Hence option c is the correct answer

a. v/|v|

Here vector v is divided by its own magnitude

b. v.|v|

Here vector v is multiplied by its own magnitude

c. v.v

Represents the square of the magnitude of vector v

d. v^2.v^2

Represents the dot product of square of vector v

For each of the following statements, write negation, contrapositive, converse and inverse. . If P is a square, then P is a rect

ValentinkaMS [17]

Step-by-step explanation:

Consider the provided information.

For the condition statement $p \rightarrow q$ or equivalent "If p then q"

The rule for Converse is: Interchange the two statements. $q \rightarrow p$
The rule for Inverse is: Negative both statements. $\sim p \rightarrow \sim q$
The rule for Contrapositive is: Negative both statements and interchange them. $\sim q \rightarrow \sim p$

The rule for Negation is: If p then q" the negation will be: p and not q. $p \rightarrow q=\sim p\vee q=p\vee \sim q$

Part (A) If P is a square, then P is a rectangle.

Here p is "P is a square", and q is "Hill and P is a rectangle".

Negation: P is a square and P is not a rectangle.

Contrapositive: If P is not a rectangle then p is not a square.

Converse: If P is a rectangle then P is a square.

Inverse: If P is not a square then P is not a rectangle.

Part (B) If n is prime, then n is odd or n is 2

Here p is "n is prime", and q is "n is odd or n is 2".

Negation: n is prime and n is even and n is not 2.

Contrapositive: If n is not odd or n is not 2 then n is not prime.

Converse: If n is odd or n is 2 then n is prime.

Inverse: If n is not prime, then n is not odd or n is not 2.

Part (C) If 2 is a factor of n and 3 is a factor of n, then 6 is a factor of n.

Here p is "2 is a factor of n and 3 is a factor of n", and q is "6 is a factor of n".

Negation: 2 is a factor of n and 3 is a factor of n and 6 is not a factor of n.

Contrapositive: If 6 is not a factor of n then 2 is not a factor of n and 3 is not a factor of n.

Converse: If 6 is a factor of n then 2 is a factor of n and 3 is a factor of n.

Inverse: If 2 is not a factor of n and 3 is not a factor of n, then 6 is not a factor of n
