Answer: L = 1.27 radians.

Step-by-step explanation:

Here we have a triangle rectangle, for the triangle rectangle and one given angle θ we have the relations:

cos(θ) = (adjacent cathetus)/hypotenuse

sin(θ) = (opposite cathetus)/hypotenuse

tan(θ) = (opposite cathetus)/(adjacent cathetus)

Here we have the adjacent cathetus = 18in, and the hypotenuse = 60in.

Sowe can use the cosine relation:

Cos(L) = 18in/60in = 0.3

Acos(cos(L)) = L = Acos(0.3) = 1.266

We want to round it to the nearest hundredth, so we would have:

L = 1.27 radians.

Question: Find The Sum Of The Integers From -6 To 58 Of Ss. O 1,500 O 1,734 O 1,690 O 1,621

REY [17]

Answer:

The Sum Of The Integers From -6 To 58 is 1690.

Step-by-step explanation:

Given,

$a=-6$

$T_n=58$

We have to find out the sum of integers from -6 To 58.

Firstly we will find out the total number of terms that is 'n'.

Here $a_1=-6\ and\ a_2=-5$

$\therefore d=a_2-a_1=-5-(-6)=-5+6=1$

Now we use the formula of A.P.

$T_n=a+(n-1)d$

On substituting the values, we get;

$58=-6+(n-1)1\\\\n-1=58+6\\\\n-1=64\\\\n=64+1=65$

So there are 65 terms in between -6 To 58.

That means we have to find the sum of 65 terms in between -6 To 58.

Now we use the formula of Sum of n_terms.

$S_n=\frac{n}{2}(2a-(n-1)d)$

On substituting the values, we get;

$S_{65}=\frac{65}{2}(2\times-6+(65-1)1)\\\\S_{65}=\frac{65}{2}(-12+64)\\\\S_{65}=\frac{65}{2}\times52\\\\S_{65}=65\times26=1690$

Hence The Sum Of The Integers From -6 To 58 is 1690.

2x + y = -4 2x + 3y = 4

kirill115 [55]

Answer: x=4 ; y= -4

Step-by-step explanation:

2x + y = -4 .(-3)

2x + 3y = 4

-6x-3y=12

2x + 3y = 4

4x=16

x= 16

x=4

2x + 3y = 4

2.4+3y=4

8+3y=4

3y= -8+4

y= -4

Which is the correct way to represent 0.0035 kg by using scientific notation? –3.5 103 kg –3.5 10–3 kg 3.5 10–3 kg 3.5 103 kg?

Vlada [557]

It would be

3.5 × 10⁻³ kg.

The decimal point must be moved 3 places to the right in order to have it behind the first non-zero digit; this gives us the exponent of 3, and since we are moving the decimal to the right, it is a negative exponent.

alexandr402 [8]

Answer: The value of cross price elasticity is 1.6.

Step-by-step explanation:

Since we have given that

Percent change in price = 10%

Percent change in quantity = 16%

So, we need to find the cross price elasticity between the two movie club memberships.

As we know the formula for cross price elasticity :

$\dfrac{\%\text{change in demand}}{\%\text{change in price}}\\\\=\dfrac{16}{10}\\\\=1.6$

Hence, the value of cross price elasticity is 1.6.
