Answer:

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (5+9+10)/3 = 24/3 = 8

∑ ( y − ȳ ) ² = ( 5 − 8 ) ² + ( 9 − 8 ) ² + ( 10 − 8 ) ²

= ( − 3 ) ² + ( 1 ) ² + ( 2 ) ²

= 9 + 1 + 4

= 14

Differential cos^2x dy/dx =e^y-tanx

gulaghasi [49]

Answer:

y=t−1+ce

−t

where t=tanx.

Given, cos

+y=tanx

⇒

+ysec

x=tanxsec

x ....(1)

Here P=sec

x⇒∫PdP=∫sec

xdx=tanx

∴I.F.=e

tanx

Multiplying (1) by I.F. we get

tanx

ysec

x=e

tanx

tanxsec

Integrating both sides, we get

tanx

=∫e

tanx

.tanxsec

xdx

Put tanx=t⇒sec

xdx=dt

∴ye

=∫te

dt=e

(t−1)+c

⇒y=t−1+ce

−t

where t=tanx

A comic book costs $3.99, including tax. It is marked up 45%.

nalin [4]

10% of 3.99=0.399x4=1.596
1% of 3.99=0.0399x5=0.1995
1.596+0.1995=1.7955
1.8(Rounded)+3.99=5.79

In Triangle ABC shown below, side AB is 6 and side AC is 4.

Amanda [17]

Answer: A is the correct option.Segment AD is 3 and segment AE is 2.

Step-by-step explanation:

Given : A triangle ABC where AC=4 and AB=6

then to prove segment DE is parallel to segment BC and half its length.

the length of AD and AE must divide AC and AB respectively to get the same ratio of 2:1

To apply converse of basic proportionality theorem.

If we take first option Segment AD is 3 and segment AE is 2 then

$\frac{AB}{AD}=\frac{6}{3}=\frac{2}{1},\frac{AC}{AE}=\frac{4}{2}=\frac{2}{1}\\\Rightarrow\frac{AB}{AD}=\frac{AC}{AE}$

Therefore by converse of basic proportionality theorem

DE is parallel to segment BC and half its length.

Therefore A is correct option.
