Answer:
a=11
Step-by-step explanation:
Let's solve your equation step-by-step.
√a+5=4
Solve Square Root.
√a+5=4
a+5=42(Square both sides)
a+5=16
a+5−5=16−5(Subtract 5 from both sides)
a=11

a=11(Works in original equation)
what force would be required to accelerate a 1,100 kg car to 0.5m/s?
Answer:
550 N
Step-by-step explanation:
We can solve the problem by using Newton's second law:
[tex]F=ma[/tex]
F is the force required to accelerate the car
m is the mass of the car
a is the acceleration of the car
In this problem, the mass is m=1100 kg, while the acceleration is a=0.5 m/s^2, therefore the force required to accelerate the car is
[tex]F=ma=(1100kg)(0.5m/s^{2} )=550N[/tex]

Suppose a group of research proposals was evaluated by a panel of experts to decide whether or not they were worthy of funding. When these same proposals were submitted to a second independent panel of experts, the decision to fund was reversed in 52 % of the cases. If the probability that a proposal is judged worthy of funding by the first panel is 0.27, what is the probability that a worthy proposal is disapproved by both panels
Answer:
0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels
Step-by-step explanation:
We have that:
0.27 = 27% of the time, the proposal is judged worthy of funding by the first panel. So 100 - 27 = 73% probability of being disapproved.
52% of the time, the independent panel reverses the decision. So if the first panel disapproves the funding, 52% probability the second approves the funding and 100 - 52 = 48% probability it does not.
What is the probability that a worthy proposal is disapproved by both panels?
48% of 73%. So
0.48*0.73 = 0.3504
0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels

AB= Round your answer to the nearest hundredth. 3 3 65 B
Answer:
AB = 7.10
Step-by-step explanation:
Reference angle = 65°
Hypotenuse = AB = ?
Adjacent side length = BC = 3
Apply the trigonometric ratio CAH, to find AB.
Cos 65 = Adj/Hyp
Cos 65 = 3/AB
AB*Cos 65 = 3
AB = 3/Cos 65
AB = 7.09860475
AB = 7.10 (nearest hundredth)

Find f(g(f(2)).
Brainliest 15 points
Answer:
10
Step-by-step explanation:
Let's find f(2) first.
f(2) = 2 + 2 = 4
This means it would be f(g(4)).
Then let's find g(4).
g(4) = 4 + 4 = 8
Then, this means f(8).
f(8) = 8 + 2 = 10

1/3x+8=12 what does x equal and show work
Answer: x = 12
Step-by-step explanation:
subtract 8 on both sides (12-8=4)
now we have 1/3x = 4
multiply 3 on both sides (4 x 3 = 12)
now we have x = 12

The size your dog and the number of times you take it to the vet, The amount your drive to school and the amount you have to pay for gas, The number of people at your party and the number of sodas you have in the refrigerator. What correlation are all of these separately. None, Positive, or Negative thanks so much and tell me which one thanks!
1. No correlation
Those things don't really relate to each other.
2. Positive correlation
The more you drive your car, the more you'll have to pay for gas.
3. Negative correlation
More people = less soda.

This week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday. If Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days?
Answer:
Jose will have played the guitar for 9.1 hours during those 6 days.
Step-by-step explanation:
Given that this week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday, to determine, if Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days, the following calculation must be performed:
3/4 = 0.75
1/2 = 0.5
(0.75 + 1.5 + 2.3) x 2 = X
4.55 x 2 = X
9.10 = X
Therefore, Jose will have played the guitar for 9.1 hours during those 6 days.
Please help me with these, find the missing side. Thank yu only if you know
Answer:
7.48m (3s.f.)
Step-by-step explanation:
Let the missing side be x m.
Applying Pythagoras' Theorem,
x² +5²= 9²
x² +25= 81
x²= 81 -25 (-25 on both sides)
x²= 56
[tex]x = \sqrt{56} [/tex]
[tex]x = 2 \sqrt{14} [/tex]
x= 7.48 (3 s.f.)
∴ The missing side is 7.48 m (3s.f.)

Find the slope of the line passing through the points (6,6) and (6, -7).
slope: 1
Answer:
The line is a vertical line, which does not have a slope.
Step-by-step explanation:
Slope of a line:
Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.
(6,6) and (6, -7).
Change in y: -7 - 6 = -13
Change in x: 6 - 6 = 0
Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

81 people passed and 27 failed their Functional Skills Level 2 exams.
Write this as a ratio in its simplest form.
Answer:
The ratio of approved and disapproved people in its simplest form is 3:1.
Step-by-step explanation:
Since 81 people passed and 27 failed their Functional Skills Level 2 exams, to write this as a ratio in its simplest form, the common greatest divisor of both numbers must be obtained:
27 is divisible by 1, 3, 9 and 27
81 is divisible by 1, 3, 9, 27 and 81
Therefore, the common greatest divisor of both numbers is 27. So, since 27/27 is equal to 1, and 81/27 is equal to 3, the ratio of approved and disapproved people in its simplest form is 3 :1.
The ratio in its simplest form is 1 : 3.
Definition of ratioRatio expresses the relationship between two numbers. It is the frequency with which a number is contained in another number. The sign used to represent ratio is ':'.
Expressing in the simplest formIn order to express the given number of people that passed and failed the exam, we have to divide both numbers by the highest common factor until both numbers cannot be divided further to yield a whole number.
Common factor of 27 and 81 = 1, 3, 9, 27
Highest common factor = 27
Expressing in the simplest form = 1 : 3

Given x^2 + y^2 = 16, find
name:
center:
Domain:
Range:
x-int
y-int
Answer:
see explanation
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 16 ← is the equation of a circle
centre (0, 0 ) and r = [tex]\sqrt{16}[/tex] = 4
The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )
and intercepts the y- axis at (0, - 4 ) and (0, 4 )
Domain is - 4 ≤ x ≤ 4
range is - 4 ≤ y ≤ 4
x- intercepts are x = - 4, x = 4
y- intercepts are - 4, 4
Answer:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 16 ← is the equation of a circle
centre (0, 0 ) and r = \sqrt{16}16 = 4
The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )
and intercepts the y- axis at (0, - 4 ) and (0, 4 )
