On a coordinate plane, a parabola opens down with solid circles along the parabola at (negative 3, negative 5), (negative 2, 0),

(negative 1, 3), (0, 4), (1, 3), (2, 0), (3, negative 5). Use the drop-down menus to identify the values of the parabola. Vertex = Domain = {x| } Range = {y| y ≤ }

Each unit on a coordinate plane represents 1 mile. One end of the road starts at (212,23). The road ends at (6,23). How long is
olya-2409 [2.1K]
Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(212,23)...x1 = 212 and y1 = 23
(6,23)......x2 = 6 and y2 = 23
now we sub
d = sqrt ((6 - 212)^2 + (23 - 23)^2)
d = sqrt ((- 206)^2 + (0^2))
d = sqrt (42436 + 0)
d = sqrt 42436
d = 206 miles <==

Find the measure of the indicated angle to the nearest degree.
eimsori [14]

1. use sin

inverse of sin(44/57) = 50.5 ---> 51°

2. use tan

inverse of tan(6/8) = 36.8 ---> 37°

3. use cos

inverse of cos(20/31) = 49.8 ---> 50°

4. use sin

inverse of sin(37/58) = 39.6 ---> 40°

Bella bought 3.2 meters of ribbon to decorate her pencil case. each meter cost $0.46. how much did the ribbon cost?
zlopas [31]

we know that

Each meter of ribbon cost \$0.46  

so

by proportion

Find the cost of 3.2 meters of ribbon

\frac{0.46}{1} \frac{\$}{meter} =\frac{x}{3.2} \frac{\$}{meter} \\ \\x=3.2*0.46 \\ \\x=\$1.472

therefore

<u>the answer is</u>

The ribbon cost \$1.472

What is the first term if term 15 is -67 and term 21 is -97?
zalisa [80]

Answer:

3

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a +(n - 1)d

where a is the first term and d the common difference

Given the fifteenth term is - 67, and term 21 is - 97, then

a + 14d = - 67 → (1)

a + 20d = - 97 → (2)

Subtract (1) from (2) term by term

6d = - 30 ( divide both sides by 6 )

d = - 5

Substitute d = - 5 into (1)

a + 14(- 5) = - 67

a - 70 = - 67 ( add 70 to both sides )

a = 3

Thus the first term is 3
