A/-8+15greater than 23
Ilia_Sergeevich [38]

Answer: a

Step-by-step explanation:

\frac{a}{-8}+15>23

Subtract 15 from both sides.

\frac{a}{-8}+15-15>23-15\\\frac{a}{-8} >8

Multiply by -8 to isolate a.

NOTE: When you multiply or divide by negative numbers, the inequality sign flips.

-8*\frac{a}{-8}>8*-8

Given: △FKL, FK=a
LuckyWell [14K]

Answer:

FL= \frac{a (\sqrt{3} + 1)}{\sqrt{2} }

Step-by-step explanation:

As given  in figure 1 below:

FK = a, m∠F = 45° and m∠L = 30°

Construction: Draw an altitude KE from point K on FL.

Now, In ΔFEK,

FE = EK (Sides opposite to equal angles of a triangle)

Let FE = EK = x  

Now, using pythagoras In  ΔFEK,

(FK)^{2} = (FE)^{2} + (KE)^{2}  

(a)^{2} = (x)^{2} + (x)^{2}

(a)^{2} = 2x^{2}

x = \sqrt \frac{a^{2} }{2} = \frac{a}{\sqrt{2} }

∴ FE = EK = \frac{a}{\sqrt{2} }

Now in ΔEKL, EK = \frac{a}{\sqrt{2} }

Using trigonometry ratio,

TanФ = Altitude\ Base

Tan \theta = \frac{KE}{EL}

Tan 30° = \frac{a/\sqrt{2} }{EL}

\frac{1}{\sqrt{3} } = \frac{a}{\sqrt{2} EL}

EL = \frac{\sqrt{3}a}{\sqrt{2} }

Now FL = FE + EL

FE = \frac{a}{\sqrt{2} } and EL = \frac{\sqrt{3}a}{\sqrt{2} }

∴ FL = \frac{a}{\sqrt{2} } + \frac{\sqrt{3}a }{\sqrt{2} } = \frac{a (\sqrt{3} + 1)}{\sqrt{2} }

Suppose cos(a)=4/5. use the trig identity sin^2(a)+cos^2(a)=1 to find sin(a) in quadrant IV.
natima [27]

Answer:

sin a = -3/5

Step-by-step explanation:

sin^2(a)+cos^2(a)=1

sin^2(a)+ (4/5)^2 = 1

sin^2(a) = 1 - 16/25 = 9/25

sin a = 3/5 ( in Quadrant 1)

In quadrat IV the sine is negative

so sin a = -3/5

What is 3.5, 3 2/5, 3 3/8 from least to greatest
pantera1 [17]

We know that 3.5 is also 3 1/2, and that 3 2/5 and 3 3/8 are both less than 3 1/2.

3.5 must be the greatest.

To convert a fraction to a decimal, divide the numerator by the denominator.

So, 3 2/5 is 3.4, and 3 3/8 is 3.375.

The order is 3 3/8, 3 2/5, and 3.5.
