The line of sight is the hypotenuse of a right triangle with short leg 400 m, 90 degree angle where the short leg meets the ground, an 83 degree angle at the top, and a 7 degree angle across from the right angle on the ground. Because this 7 degree angle is an alternate interior angle with the angle of depression, they are the same degree measure. Looking for the hypotenuse, we use the sin ratio: sin (7) = 400/x.

Write the following quadratic in standard form. Then identify a, b, and c.<br> y² - 7y + 6 = -6
Charra [1.4K]

Answer:

Therefore,

y^{2}-7y+12=0       ....Standard form.

a=1\\b=-7\\c=12    ......Numerical Coefficients.

Step-by-step explanation:

Given:

y^{2}-7y+6=-6

To Find:

a ,b , c

Solution:

Quadratic:

A quadratic equation is an equation of the second degree.

Meaning it contains at least one term that is squared.

The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

Here it is given as

y^{2}-7y+6=-6

Adding 6 on both the side we get

y^{2}-7y+6+6=-6+6

y^{2}-7y+12=0

Which is Quadratic Equation in STANDARD form Where,

a=1\\b=-7\\c=12

Therefore,

y^{2}-7y+12=0       ....Standard form.

a=1\\b=-7\\c=12    ......Numerical Coefficients.

In a table do you have to list the x and y coordinates in order (largest to smallest)?
Arisa [49]

Answer:

No. (maybe)

Step-by-step explanation:

For expressing the corresponding values of x and y, <em>any ordering will do</em>. It is usually convenient for the user of the table if there is some recognizable order (so that a value can be found without searching the entire table). The usual expected order is by x-value, smallest to largest.

Some problem statements may specify that the table entries be listed in order. In those cases, yes, the <em>table values must be listed as specified</em>. (This accounts for the (maybe) answer, above.)

nordsb [41]

Step-by-step explanation:

speed = distance/time

time = t = distance/speed

t = 180/b + (400-180)/c = 180/b + 220/c = 20(9/b + 11/c)
