F(x) = 5x²-3
g(x) = 5x + 3
a. both fand g open downward; low point of fis 3 units below the x-axis; the low point of g is 3 units above
the x-axis
b. both fand g open upward; low point of fis 3 units above the x-axis; the low point of g is 3 units below
the x-axis
c. both fand g open upward; low point of fis 3 units below the x-axis; the low point of g is 3 units above
the x-axis
both fand g open downward; low point of fis 3 units above the x-axis; the low point of g is 3 units below
the x-axis
d.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: 12

step-by-step explanation:

because yes

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

so what is the problem what are they asking you to solve
