Value of the y-intercept of the graph of f(x) = e1–x – 1?

Mathematics
1 answer:
frozen [14]4 years ago
5 0

Answer:

(0, e-1) or (0, 1.718) to the nearest thousandth.

Step-by-step explanation:

The y-intercept occurs when x = 0 so here we have:

y = e^(1 - 0) - 1

= e - 1

So the y-intercept is the point (0, e-1)

Elena-2011 [213]

Answer:

The 2 integers would be: 2 and 8

Step-by-step explanation:

2 + 8 = 10

Reciprocal of 2: 1/2

Reciprocal of 8: 1/8

1 / 2 - 1 / 8 = 4/8 - 1/8 = <u>3/8</u>

Given: tangent A = negative StartRoot 15 EndRoot What is the value of Tangent (A minus StartFraction pi over 4 EndFraction)?
marshall27 [118]

Answer:

( √15 + 8)/7

Step-by-step explanation:

TanA = -√15

.we are to find tan(A-π/4).

In trigonometry

Tan(A-B) = TanA - TanB/1+ tanAtanB

Hence:

tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4

Substitute tan A value into the formula

tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4

tan(A-π/4) = -√15-1/1-√15

Rationalize

-√15-1/1-√15 × 1+√15/1+√15

= -√15-√225-1-√15/(1-√225)

= -2√15-15-1/1-15

= -2√15 -16/(-14)

= -2(√15+8)/-14

= √15 + 8/7

Hence the required value is ( √15 + 8)/7

Answer:

\boxed{\bold{< \ -\frac{2}{8}}}

Step-by-step explanation:

Find LCD of the two fractions

LCD = 24

Rewrite fractions

\bold{-\frac{16}{24} } ____ \bold{-\frac{6}{24} }

Just because 6 is smaller than 16, doesn't mean 6 isn't larger. If you have more of something, the portions will be smaller. If you have less of something, the portions will be bigger.

\bold{-\frac{2}{3} } < \bold{-\frac{2}{8} }
