<h2>Answer:</h2>

<u>The answer is</u><u> -7</u>

<h2>Step-by-step explanation:</h2>

Taking the equation

= −4 + (−5) + 2

Negative and positive will multiply to give us a negative

= −4 −5 + 2

= −9+2

=−7

a country's population in 1990 was 134 million. in 2000 it was a 139 million. estimate the population in 2014 using the exponent

yuradex [85]

F=ir^t

139=134r^10

139/134=r^10

r=(139/134)^(1/10) then:

f=134(139/134)^(t/10) so in 2014, t=24 so

f=134(139/134)^(2.4)

f≈146 million (to nearest million)

Some will say that you have to use the exponential function, but it really gives you the same answer...even for continuous compounding :)...

A=Pe^(kt)

139=134e^(10k)

139/134=e^(10k)

ln(139/134)=10k

k=ln(139/134)/10 so

A=134e^(t*ln(139/134)/10) when t=24

A=134e^(2.4*ln(139/134))

A≈146 million (to nearest million)

The only real reason or advantage to using A=Pe^(kt) is when you start getting into differential equations...

The diagram shows TUV. Which term describes point W?

alex41 [277]

A. incenter

point w is shown in the triangle formed by 3 different lines. these lines are called angle bisectors, and the point at which the angle bisectors meet is called the incenter of a triangle

A distance is related to time according to the expression x = A sin(2πft), where A and f are constants. Find the dimensions of A

nika2105 [10]

Answer:

[M⁰L¹T⁰]

Step-by-step explanation:

given expression,

from the expression x = A sin (2 π f t),

A and f are constants

dimension of A =?

As the sine factor is dimensionless means that sine function will not have any dimension it is dimensionless.

so, remaining

x = A sin ()

so, the dimension of x is L

hence, the dimension of A also will be equal to L i.e [M⁰L¹T⁰]

3. In AABC, a = 35, c = 25, and m can be drawn given these measurements?

Flauer [41]

Only one triangle possible with angle 38.2° at C.

According to the given statement

we have to seek out that the measurement of m with the help of the a and c.

Then for this purpose, we all know that the

The ambiguous case occurs when one uses the law of sines to see missing measures of a triangle when given two sides and an angle opposite one in every of those angles (SSA).

According to the this law

The equation become

35/sin(60) = 25/sinC

sinC = 0.6185895741

C = 38.2, 141.8

Since 141.8+60 = 201.8 > 180

It will not form a triangle.

So, only 1 triangle possible with angle 38.2° at C
