Given that y varies indirectly as x and that x = 15 when y = 3, then the value of k is
Answer:
Step-by-step explanation:
the equation of this function has the form y = k/x, and when x = 15 and y = 3, the value of k can be calculated as follows:
3 = k/15, or (by multiplying both sides by 15) k = 45
Then y = 45/x

Step-by-step explanation:
If he plans to cook 16 of less hotdogs, h is going to be equal to or less than 16. The circle is closed because he could cook 16.
Answer:
For the first question it would be answer 4
Since they ask you "at most 16 hot dogs," that means that it has to be less than or equal to 16.
For the second question, you would put the endpoint on 16 and make the arrow going left.
The measurement of angle DBE is 0.1x-33 and the measurement of angle CBE is 0.3x-39 what's the value of x
Answer:
x = 405
Step-by-step explanation:
DBE is 0.1x-33 and the measurement of angle CBE is
The sum of both angles form a right angled triangle ;
DBE + CBE = DBC
DBC = RIGHT angled triangle = 90°
(0.1x-33) + (0.3x - 39) = 90°
0.1x - 33 + 0.3x - 39 = 90°
0.1x + 0.3x - 33 - 39 = 90
0.4x - 72 = 90
0.4x = 90 + 72
0.4x = 162
x = 162 / 0.4

The polynomial of degree 4, P(x) has a root of multiplicity 2 at x=1 and roots of multiplicity 1 at x=0 and x=-3. It goes through the point (5,256)
Answer:
P(x) = ([tex]\frac{2}{5}[/tex])x(x + 3)(x - 1)²
Step-by-step explanation:
Given - The polynomial of degree 4, P(x) has a root of multiplicity 2 at x=1 and roots of multiplicity 1 at x=0 and x=-3. It goes through the point (5,256)
To find - Formula for P(x) ?
Proof -
Given that,
P(x) has a root of multiplicity 2 at x=1
So,
(x - 1)² is a factor.
Now,
Given that, there is roots of multiplicity 1 at x=0 and x=-3
So,
(x - 0) and ( x - (-3) are also factor
So,
P(x) can be written as
P(x) = Ax(x + 3)(x - 1)² .........(1)
where A is a constant.
Now,
Given that, It goes through the point (5,256)
⇒At x = 5, P(x) = 256
So,
Put the values of x and P(x) in equation (1), we get
P(x) = Ax(x + 3)(x - 1)²
⇒256 = A(5)(5 + 3)(5 - 1)²
⇒256 = 5A(8)(4)²
⇒256 = 40A(16)
⇒256 = 640 A
⇒A = [tex]\frac{256}{640}[/tex] = [tex]\frac{2}{5}[/tex]
∴ we get
P(x) = ([tex]\frac{2}{5}[/tex])x(x + 3)(x - 1)²

The polygons are similar. x = ___ Write your answer as a decimal
By using the fact that the two images are similar, we can write and solve a linear equation to get x = 3/2.
How to find the value of x?We know that the two figures are similar, then, if we take the quotient between the adjacent sides for both figures, these quotients should give the same value.
Thus, we can write the equation:
14/10 = (x + 9)/(x + 6)
Now we can solve that equation for x, if we multiply both sides by (x + 6) we will get:
(14/10)*(x + 6) = x + 9
Now we can multiply both sides by 10 to get:
14*(x + 6) = 10*(x + 9)
14x + 84 = 10x + 90
Now we can solve this linear equation for x.
14x - 10x = 90 - 84
4x = 6
x = 6/4
x = 3/2
That is the value of x.

Hannah either walks or cycles to school. The probability that she walks to school is 0.75 If she walks, the probability that she is late is 0.6 If she cycles, the probability that she is late is 0.2 Work out the probability that on any one day Hannah will not be late for school.
If Hanna is walking there is a 0.4 chance of not being late. 0.75 x 0.4 = 0.3 probability of not being late.
If Hanna cycles there is a chance of 0.8 of not being late. 0.6 x 0.8 = 0.48.
0.48 + 0.3 = 0.78.
In other words, there is a 78% probability of her not being late.

What is the x in 4x+20?
Answer:
the answer is 5 because if you divide it its your answer
Answer:
x=-5
Step-by-step explanation:
Set " 4x+20" equal to 0 (4x+20=0)
Do the opposite operation of 20 (in this case is subtraction) and subtract 20 from both sides (4x+20-20=0-20).
You'll be left with 4x=-20.
Divide both sides by 4 (4x/4=-20/4).
4 divided 4 equals x.
-20 divided by 4 equals -5.
x=-5.

Here, a=4+k, b=2k+4, c=8k+1
The given equation will be a perfect square, When D= 0
We know, D = b^2−4ac [A perfect square trinomial is an expression that can be generated from the square of a binomial equation. If an equation has the formula ax^2 + bx + c and meets the requirement b^2 = 4ac, it is referred to as a perfect square trinomial.

What is nuclear fission?Nuclear reactions are those that involve the nucleus of an atom. Nuclear fission involves the splitting of an atomic nucleus and the formation of two distinct atomic species.
Nuclear fission is a nuclear reaction in which the nucleus of an atom is split into two or more smaller nuclei, along with the release of a large amount of energy. In the first reaction, an atom of Uranium-235 (U-235) is hit by a neutron, which causes the nucleus to split into Krypton-90 (Kr-90) and Barium-141 (Ba-141) along with 3 neutrons. In the second reaction, an atom of Plutonium-239 (Pu-239) is hit by a neutron, which causes the nucleus to split into Strontium-96 (Sr-96) and Barium-143 (Ba-143) along with 3 neutrons.

What is the distance between the points (3,7) and (-2, 10)
Answer:
√34
Step-by-step explanation:
To find the distance between two points, you can use the distance formula, which is:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
We can plug in the points (3, 7) and (-2, 10) to get:
d = √[(-2 - 3)^2 + (10 - 7)^2]
We can simplify.
d = √[(-5)^2 + (3)^2]
d = √(25 + 9)
d = √(34)
d = √34
