Answer 1

Answer:

Answer:

∠3 = 62°

Step-by-step explanation:

The diagonals of a kite are at right angles to each other, hence

Triangle containing ∠ 3 is a right triangle

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

90 + 28 +∠3 = 180

118 + ∠3 = 180 ( subtract 118 from both sides )

∠3 = 62°

Order the quadratic functions from widest to narrowest graph. y=4x^2 y=2x^2 y= 0.15x^2

Answers

ANSWER

$y=0.15x^2, y=2x^2,y=4x^2$

EXPLANATION

The given quadratic functions are;

$y = 4 {x}^(2)$
$y = 2 {x}^(2)$
and

$y = 0.15 {x}^(2)$

A fractional coefficient indicates a horizontal stretch.

The smaller the coefficient, the wider the stretch for
$|a| < 1$
and

$a \ne0$

Also
$|a| > 1$
indicates a horizontal compression.

The higher the value the narrower the graph.

Therefore from widest to narrowest, we have,

$y=0.15x^2, y=2x^2,y=4x^2$

See graph.

What are the first four terms of the sequence represented by the expression n(n-2)-3

Answers

Answer:

As per the statement:

Given a sequence:

$a_n = n(n-2)-3$

where, n is the number of terms;

We have to find the first four terms of this sequence:

For n =1

$a_1 = 1(1-2)-3 =1(-1)-3 = -1-3 = -4$

⇒ $a_1 = -4$

For n =2

$a_2= 2(2-2)-3 =2(0)-3 = 0-3 = -3$

⇒ $a_2 = -3$

For n =3

$a_3 = 3(3-2)-3 =3(1)-3 = 3-3 = 0$

⇒ $a_3= 0$

For n =4

$a_4 = 4(4-2)-3 =4(2)-3 = 8-3 = 5$

⇒ $a_4= 5$

Therefore, the first four terms of the sequence are:

-4, -3, 0 , 5

$a_n=n(n-2)-3 \n \na_1=1(1-2)-3=1 * (-1)-3=-1-3=-4 \na_2=2(2-2)-3=2 * 0-3=0-3=-3 \na_3=3(3-2)-3= 3 * 1-3=3-3=0 \na_4=4(4-2)-3=4 * 2 -3 =8-3 =5$

The first four terms are -4, -3, 0, 5.
