-4.9t^2 + 6.1t - 0.8 = 0
Subtract 3 from both sides
Answer:
the exact answer is 1.98
if we rationalize denominator we get root 0f 10 times pi divided by 5
root of 10 is about 3.1 (
) so we have
≈ 9.6/5 = 1.92
Step-by-step explanation:
= 
Graph using slope and the y intercept
So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1
The next graph plot y intercept (0,-1) and then go down 2 and to the right 1
And should look like the image
And your solution should be (-2,3) which is option c
Answer:
3. A=B=70°; C=D=110°
4. A=90°; C=48°
Step-by-step explanation:
Same-side angles of a trapezoid add to 180°.
___
3. (2x) +(x+15) = 180
3x + 15 = 180 . . . . simplify
x +5 = 60 . . . . . . . divide by 3
x = 55
A=B=(x+15)° = (55+15)° = 70°
C=D=2x° = 2·55° = 110°
__
4. You are given the values of one of the angles on each side, so the other can be found by subtraction:
A=180°-D = 90°
C = 180° -132° = 48°
Answer:
2.3
Step-by-step explanation: if your finding the decimal 2.3 will be your answer if not then sorry
