Quartic expression

Answers

Answer 1

Answer:

Answer:it is a linear expression

Step-by-step explanation:

Linear expressions or equations are expressions in which the highest power of the variable is one.

Quadratic expressions or equations are expressions in which the highest power of the variable is two.

Cubic expressions or equations are expressions in which the highest power of the variable is three.

Quartic expressions or equations are expressions in which the highest power of the variable is four.

From the expression, 5x + 2 given,

the highest power of x is one. So it is a linear expression.

Answer 2

Answer: It is Linear expression

A candle is 17 in. tall after burning for 3 hours. After 5 hours, it is 15 in. tall. Write a linear equation to model the relationship between heigh h of the candle and time t. Predict how tall the candle will be after 8 hours.

Answers

Let

x------> the time in hours

y------> the height in inches

$A(3,17)\nB(5,15)$

Step $1$

Find the slope m of the linear equation between points A and B

we know that

The formula to calculate the slope between two points is equal to

$m=((y2-y1))/((x2-x1))$

substitutes the values

$m=((15-17))/((5-3))$

$m=((-2))/((2))$

$m=-1$

Step $2$

Find the equation of the line

we know that

the equation of the line in the point-slope form is

$y-y1=m*(x-x1)$

we have

$m=-1$

$A(3,17)$

substitute in the equation

$y-17=-1*(x-3)$

$y=-x+20$ --------> this is the linear equation that model the relationship between height h of the candle and time t

Step $3$

Find the height for $x=8$ hours

substitute the value of x in the linear equation

$y=-8+20$

$y=12\ inches$

The height of the candle will be $12\ inches$ after $8\ hours$

For the linear equation you have two points (3, 17) and (5, 15) so the equation is: h-17=(15-17)/(5-3)*(t-3), solve for h= -t+20.
For predicting, only replace t=8 into you equation (h= -t+20) and you will get h=-8+20=12

A triangle has side lengths of 7, 24, and 26. Is the triangle right, acute, or obtuse? A) Right
B) Acute
C) Obtuse

Answers

We use the Pythagorean theorem to determine if the side lengths given will result to either a right, acute, or obtuse triangle.

a = 7 ; b = 24 ; c = 26

a² + b² = c² ⇒ right triangle
a² + b² > c² ⇒ acute triangle
a² + b² < c² ⇒ obtuse triangle

7² + 24² = > < 26²
49 + 576 = > < 676
625 < 676 OBTUSE TRIANGLE

The entrance to a horizontal mining tunnel has collapsed, trapping the miners inside.The rescue team decide to drill a vertical escape shaft from a position 200 m further

need to be to meet the horizontal tunnel? Answer to one decimal place.

Answers

Answer: 78.1 meters

Explanation

The diagram is shown below.

We have a right triangle with an unknown vertical leg (which I'll call x) and a known hypotenuse that is 200 meters long.

We use the sine ratio to connect the opposite and hypotenuse.

sin(angle) = opposite/hypotenuse

sin(23) = x/200

x = 200*sin(23)

x = 78.1462256978548 approximately

x = 78.1
