How do you solve for x? 1953=x(x+1)/2

1 answer:

6 0

*1953 = x(x + 1) /2 2* 1953 = x (x + 1) 3906 = x^2 + x x^2 + x - 3906 = 0 (X + 63) (x - 62) =0 X + 63 = 0. ^ x - 62 = 0 X = -63 ^ x = 62 :)

We want to solve
$3e^{2x}+5=27$

Subtract 5 from each side.
$3e^{2x}=22$
Divide each side by 3.
$e^{2x}=7.3333$
Take natural logs of each side.
$2x=ln(7.3333)=1.9924$
Divide each side by 2.
x = 0.9962

Answer: x = 0.996 (nearest thousanth)

The regular nonagon has rotational symmetry of which angle measures? Check all that apply.

11111nata11111 [884]

Consider the center of the nonagon. If we join the center to all the vertices, the central angle of 360°, is divided into 9 equal angles, each with a measure of:

360°/9=40°

So to a nonagon rotated 40°, clockwise or counterclockwise, is indistinguishable from the original one.

similarly if we rotate 80 ° c.wise or c.c.wise

in general, a nonagon has a rotational symmetry of 40°n,

where n∈{...-3, -2, -1, 0, 1, 2, 3}...

where 40°n, for n negative, means we are rotating clockwise.

Answer: any angle which is a multiple of 40°

Answer:

3515

Step-by-step explanation:

Data provided in the question:

Dimension of the container = 1.5 m x 18 cm x 28 cm

volume of the container = 150 cm × 18 cm × 28 cm = 75600 cm³

also,

1 L = 1000 cm³

thus,

volume of the container = $\frac{75600}{1000}$ = 75.6 L

Volume of the U.S pint = 0.4732 L

therefore,

Number of pint in the container = $\frac{\textup{Volume of container}}{\textup{Volume of pint}}$

= $\frac{\textup{75.6 L}}{\textup{0.4732 L}}$

= 159.76

Also it is given that

Number of Pacific oysters per pint = 10

Number of Atlantic oysters per pint = 32

Thus,

for 159.76 pint

Pacific oysters in container = 10 × 159.76 = 1597.6 ≈ 1598

Atlantic oysters in the container = 32 × 159.76 = 5112.42 ≈ 5113

hence,

order short of your anticipated count = 5113 - 1598 = 3515
