What does the expression 1.5b+75b

Answer:

A

Step-by-step explanation:

We are given that:

[tex]\tan(\theta)=1.3[/tex]

And we want to find:

[tex]\cot(90^\circ -\theta)[/tex]

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:

[tex]\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)[/tex]

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.

Our answer is A.

Answer:

(y+6)(y-1)

Step-by-step explanation:

literally factorising.

y^2 x -6 = -6y^2

u need two numbers that multiply to make -6 and add them together to make +5 which is +6 and -1.

Answer:

p = 6, q = - 1 , or p = - 1, q = 6

Step-by-step explanation:

Factorise the quadratic expression on the left side

y² + 5y - 6

Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)

The factors are + 6 and - 1 , since

6 × - 1 = - 6 and 6 - 1 = + 5 , then

y² + 5y - 6

= (y + 6)(y - 1) = (y - 1)(y + 6)

Compare to (y + p)(y + q) , then

p = 6, q = - 1 or p = - 1, q = 6

8 · 0.25 = $2

3 · 0.10 = $0.30

4 · 0.01 = $0.04

Answer:

533.109

Step-by-step explanation:

Just add all the numbers

Answer:

6

Step-by-step explanation:

As x approaches -10 from the left, f(x) approaches -4 + 10 = 6

As x approaches -10 from the right, f(x) approaches -10 + 16 = 6

f(-10) = 6

Putting that all together, we have a limit of 6

Answer:

x = 5

Step-by-step explanation:

Since both triangles are similar hence;

m<CAB = m<CDE

Given theta

m<CAB = 50degrees

m<CDE = 10x

Substitute the given angles

50 = 10x

Swap

10x = 50

Divide both sides by 10

10x/10 = 50/10

x = 5

Hence the value of x is 5

The Cartesian coordinate system, also called the rectangular coordinate system, is based on a two-dimensional plane consisting of the x-axis and the y-axis. 

Answer:

B.12

Step-by-step explanation:

For your first draw you have 4 possible options, then on your second draw you have 3 possible options since you took out a pair. So to figure out the number of possible outcomes you simply multiply the possibilities by each other to get the number of possible outcomes.

Answer:

26 gallons of gas

Step-by-step explanation:

168 miles = 14 gallons of gas

312 miles = x gallons of gas

168 miles/14 gallons of gas = 312 miles/x gallons of gas

x = [tex]\frac{312 * 14 }{168}[/tex]

x = 26 gallons of gas

I think this is the answer

Complete question :

A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.

1-What percentage of adult men can fit through the door without bending?

2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below

A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.

B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.

C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.

Answer:

A.) 0.135%

B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

C.)

Step-by-step explanation:

Percentage of adult men that can fit the door without bending :

Obtain the Zscore :

Mean height of men, m = 67.5

Standard deviation, s = 3.7

Zscore = (x - m) / s ; where x = 56.4

Zscore = (56.4 - 67.5) / 3.7

Zscore = - 11.1 / 3.7

Zscore = - 3

P(Z < - 3) = 0.0013499 (Z probability calculator)

P(Z < - 3) = 0.0013499 * 100% = 0.13499%

Answer:

x = -7, y = 3

Step-by-step explanation:

x = -2y - 1

x = 3y - 16

so:

-2y - 1 = 3y - 16

add 2 y to each side of the equation:

-1 = 5y - 16

add 16 to each side:

5y = 15

divide both sides by 5:

y = 3

x = 3(3) - 16 = -7

Answer:

(x+c)(x-d)

Step-by-step explanation:

if x²-ax-b=(x-c)(x+d)

from vieta theorem

c + d =  -(-a)=a

cd = b

if x²+ax-b

from vieta theorem

c + d =  -(a)=-a  

cd = b

so the same c d but in opposite  sign (x+c)(x-d)

Answer:

The vertex (your "point") is (-25, -5).

Step-by-step explanation:

Compare the given equation to

y - k = m(x - h).  We see that the slope, m, is 9/4; the x-coordinate of the vertex is h = -25, and the y-coordinate of the vertex is k = -5.

The vertex (your "point") is (-25, -5).
