x^o+63^o=90^o\ \ \ \ |-63^o\\\\x^o=27^o

Answer:

\boxed{x\degree+63\degree=90\degree}

Step-by-step explanation:

The symbol \boxed{}, is used to indicate a right angle.


This implies that, the x degree angle and the 63\degree angle will add up to 90\degree.


In other words, the two angles are complementary.


The equation that we can use to solve for x is

x\degree+63\degree=90\degree


When we solve for x, we get


x=90-63


\Rightarrow x=27\degree

The table shows the height of a softball that Hallie threw in the air. Is the relationship shown linear? Why or why not?
andrew11 [14]

Answer:

Not a linear relationship

Step-by-step explanation:

Given

The attached table

Required

Linear or not

To do this, we simply calculate the slope of the table at different intervals.

Slope (m) is calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1,y_1) = (0,0)

(x_2,y_2) = (0.5,7.2)

So, the slope is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{7.2 - 0}{0.5-0}

m = \frac{7.2}{0.5}

m = 14.4

Let:

Let:

(x_1,y_1) = (1,10.7)

(x_2,y_2) = (2,12.2)

So, the slope is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{12.2 - 10.7}{2 - 1}

m = \frac{1.5}{1}

m = 1.5\\

See that the calculated slopes are not equal.

Hence, it is not linear

Which expressions are equivalent to 25x^4–64? select three options.
BARSIC [14]
<h2>The equivalent expression of 25x^4 - 64 are "a), b) and c)".</h2>

Step-by-step explanation:

The given expression is:

25x^4 - 64

To find, the equivalent expressions are:

a) 25x^4 + 40x - 40x - 64

=  25x^4 - 64, is the equivalent expression.

b) 25x^4 + 13x - 13x - 64

=  25x^4 - 64, is the equivalent expression.

c) (5x^2 + 8)(5x^2 - 8)

Using the algebraic identity,

(a + b)(a - b) = a^{2}-b^{2}

= (5x^2)^2-8^2

=  25x^4 - 64, is the equivalent expression.

d) (x^2 + 13)(x^2 - 13)

Using the algebraic identity,

(a + b)(a - b) = a^{2}-b^{2}

= (x^2)^2-13^2

=  x^4 - 169, is not a equivalent expression.

e) (5x^2-8)^2

Using the algebraic identity,

(a-b)^{2} =a^{2} -2ab+b^2

= (5x^2)^{2} -2(5x^2)(8)+8^2

= 25x^4 -80x^2+64,  is not a equivalent expression.

∴ The equivalent expression of 25x^4 - 64 are "a), b) and c)".
