The value of given expression is 3

<em><u>Solution:</u></em>

Given that we have to simplify the given expression and find its value when x = 0.97

<em><u>Given expression is:</u></em>

(x - 10)^2 - x(x + 80)

Multiply "x" with terms inside bracket

\rightarrow (x-10)^2-x^2-80x

Substitute x = 0.97

\rightarrow (0.97-10)^2-(0.97)^2-80(0.97)\\\\\rightarrow (-9.03)^2-0.9409 - 77.6\\\\\rightarrow 81.5409 - 0.9409 - 77.6\\\\\rightarrow 80.6 -77.6 = 3

Thus value of given expression is 3

The first equation in the system models the height in feet, h, of a falling baseball as a function of time, t. the second equati
Sonja [21]

The height of the baseball is 6 feet at the moment the player begins to leap. Then the correct option is D.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The first equation in the system models the height in feet, h, of a falling baseball as a function of time, t. the second equation models the height in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

h(t) = 35 - 16t²

h(t) = 6 + 18t + 16t²

At t = 0, Then we have

h(0) = 35 - 16(0)²

h(0) = 35

And

h(0) = 6 + 18(0) + 16(0)²

h(0) = 6

The height of the baseball is 6 feet at the moment the player begins to leap.

More about the function link is given below.

Out of 460 students, 60% have pets. How many of the students have pets?
Margaret [11]
In order to find the number, we will need to set it up in an equation. In total, there are 460 students while 60% of them have pets. Lets set that up.
460(60%)
In order to correctly do this, we will need to transfer 60% into a decimal, which is .6. Now we will rewrite it.
460(.6) 
This now can be represented by the number 276.Since we know that 276 is 60% of 460, The total number of students that have pets will be 276.

Y-80x=65 in function notation
kolezko [41]

Answer:f(x) = 80x + 65f


Step-by-step explanation:

Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:

(625 - 465) / (7 - 5) = 160/2 = 80

Then, use m = 80 and one of the points to write the equation of your line in point-slope form:

y - y1 = m(x - x1)

y - 465 = 80(x - 5)

Convert that to standard form:

y = 80(x - 5) + 465

y = 80x - 400 + 465

y = 80x + 65

y - 80x = 65

In function notation, that's:

f(x) = 80x + 65

Prove, Cosec2A + cot2A = cotA​
elena-s [515]

Proved

Step-by-step explanation:

Cosec2A + cot2A = cotA​

On Left hand-side

Cosec2A + cot2A = \frac{1}{sin2A} +\frac{cos2A}{sin2A} \\\\\\

=\frac{1}{2sinAcosA} +\frac{2cos^2A-1}{2sinAcosA}

\frac{1+2cos^2A-1}{2sinAcosA} \\\\\\=\frac{2cos^22A}{2sinAcosA} \\\\=\frac{cosA}{sinA} \\\\\\=cotA
