VashaNatasha [74]

Answer:

90 degrees is a right angle.

Step-by-step explanation:

^ That would be a 90 degrees angle.

|____

|___|____________

Imagine this is a graph, that little square of the right would represent 90 degrees.

Angles less than 90 are acute angles, angles over 90 but under 180 degrees would be obtuse, and angles that are equal to 180 degrees are straight.

Lorne subtracted 6x3 – 2x + 3 from –3x3 + 5x2 + 4x – 7. Use the drop-down menus to identify the steps Lorne used to find the dif

Novay_Z [31]

Answer: Step 1: Reverse the signs of $6x^3-2x + 3$ expression.

Step 2: Removing parenthesis

Step 3: Grouping like terms

Step 4: Combing like terms

Step 5: Writing the final expression in standard form

Step-by-step explanation: First expression : $6x^3-2x + 3$

Second expression : $-3x^3+5x^2+4x-7$ .

We need to subtract $6x^3-2x + 3$ from $-3x^3+5x^2+4x-7$ .

Step 1: Reverse the signs of $6x^3-2x + 3$ expression.

$(-3x^3+5x^2+4x-7)+(-6x3+2x-3)$

Step 2: Removing parenthesis

$(-3x^3) +5x^2+4x + (-7) + (-6x^3) + 2x + (-3)$

Step 3: Grouping like terms

$[-3x^3) + (-6x^3)] + [4x + 2x] + [(-7) + (-3)] + [5x^2]$

Step 4: Combing like terms

$-9x^3 + 6x + (-10) + 5x^2$

Step 5: Writing the final expression in standard form

$-9x^3 + 5x^2 + 6x-10$

H=7+44t-16^2

djyliett [7]

Answer:

$t_1\approx2.18$

$t_2\approx0.57$

Step-by-step explanation:

$h=7+44t-16t^2$

$27=7+44t-16t^2$

$0=-20+44t-16t^2$

$0=-16t^2+44t-20$

$t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$t=\frac{-44\pm\sqrt{44^2-4(-16)(-20)}}{2(-16)}$

$t=\frac{-44\pm\sqrt{1936-1280}}{-32}$

$t=\frac{-44\pm\sqrt{656}}{-32}$

$t=\frac{-44\pm4\sqrt{41}}{-32}$

$t=\frac{11}{8}\pm\frac{\sqrt{41}}{8}$

$t_1\approx2.18$

$t_2\approx0.57$
