Answers
Answer:
W = 13 + 4.5l + 3s
Step-by-step explanation:
We would have to add 13 because it's the natural weight. We don't know how many apples there are, but we know much weight is in each one. We will use the letters as the unknown. Then we will use 4.5 for L, and 3 for s

Answers
The nuclear binding energy for thorium -234 is 2.78 × 10-10 j
We have given that,
Kilograms are represented by the mass defect for thorium
-234 = 3.09 × 10-27 kg
To determine the nuclear binding energy for thorium -234.
What is the relation between Mass defect and binding energy?ΔE = Δmc^2
Where
ΔE = binding energy
Δm = mass defect
c = speed of light
mass defect = 3.09× 10^-27 kg
We know that the speed of light = 3 × 10^8 m /s
[tex]\Delta E \\= 3.09\times 10^{-27} kg (3 \times 10^8 m /s)^2 \\= 2.781 \times 10^{-10} J / Kg[/tex]

D. As the input increases, the output decreases for all values of x.
Option A
It's a parabola having vertex (-1,-5)
As we can see the graph .
The curve first decreases until it reaches the vertex (-1,-5) then it increases on increase in x

One sector has an area of 167 square inches and an arc measure of 110°.
Answers
The area of the circle that contains the sector is 546.5 in² (rounded to the nearest tenth)
Calculating area of a circleFrom the question, we are to determine the area of the circle.
The area of a circle can be determined by using the formula,
[tex]A = \pi r^{2}[/tex]
From the given information,
Area of the sector = 167 in²
Arc measure = 110°
Using the formula,
[tex]Area\ of\ sector = \frac{\theta}{360 ^\circ} \times \pi r^{2}[/tex]
Then,
[tex]167= \frac{110 ^\circ}{360 ^\circ} \times \pi r^{2}[/tex]
[tex]167= \frac{11}{36} \times \pi r^{2}[/tex]
[tex]\pi r^{2} =\frac{167 \times 36}{11}[/tex]
[tex]\pi r^{2} = 546.5 \ in^{2}[/tex]
Since area of the circle, A, is given by πr²
Then,
A = 546.5 in²
Hence, the area of the circle that contains the sector is 546.5 in²

Which polynomials are prime? check all of the boxes that apply. x2 9 x2 – 9 x2 3x 9 –2x2 8
Answers
Prime polynomials cannot be factorized in smaller degree polynomials. The prime polynomials out of the considered option are:
Option 1: x^2 + 9Option 3: x^2 + 3x + 9What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Checking all the options for them being prime or not:
Option 1: [tex]x^2 + 9[/tex]Take [tex](x+a)(x+b) = x^2 + 9[/tex]
Then, expanding it gives:
[tex]x^2 + (a+b)x + ab = x^2 + 9 \implies a+b = 0, ab = 9[/tex]
or we get: [tex]a = -b, ab = -b^2 = 9, b^2 = -9[/tex]
Square of a real number doesn't exist, so this factor doesn't exist. Thus, it is prime polynomial.
Option 2: [tex]x^2 - 9[/tex]We have the identity [tex](a+b)(a-b) = a^2 - b^2[/tex]
and since 9 is square of 3, therefore, we get:
[tex]x^2 -9 = x^2 -3^2 = (x+3)(x-3)[/tex]
So it got factorized. Thus, not a prime polynomial.
Option 3: [tex]x^2 +3x + 9[/tex]Take [tex](x+a)(x+b) = x^2 + 3x + 9[/tex]
Then, expanding it gives:
[tex]x^2 + (a+b)x + ab = x^2 + 3x + 9 \implies a+b = 3, ab = 9[/tex]
That gives:
[tex]a = 3-b\\ab = b(3-b) = 3b - b^2 = 9\\b^2 -3b + 9 = 0[/tex]
Solving this quadratic equation by root formula gives:
[tex]b = \dfrac{-(-3) \pm \sqrt{(-3)^2 -4(1)(9)} }{2}\\\\b = \dfrac{-(-3) \pm \sqrt{-27} }{2}\\[/tex]
this makes 'b' a complex number and it doesn't remain a real number as its expression contains square root of a negative number.
Thus, this polynomial cannot be factorized in terms of smaller degree polynomials. Thus, its a prime polynomial.
Option 4: [tex]-2x^2 + 8[/tex]Taking -2 common out, we get:
[tex]-2(x^2 - 4) = -2(x^2 - 2^2) = -2(x-2)(x+2)[/tex]
Thus, it got factorized, and therefore not a prime polynomial.
Thus, the prime polynomials out of the considered option are:

What is the vertex?
(X= -b/2a)
What is the Y intercept?
Answers
Step-by-step explanation:
any quadratic equation has the form
y = ax² + bx + c
so, we can see in our case
a = 1
b = 8
c = 7
the x value of the vertex is indeed camcorders by
x = -b/(2a) = -8/2 = -4
the corresponding y we get then
y = (-4)² + 8×-4 + 7 = 16 - 32 + 7 = -9
the vertex = (-4, -9).
the y- intercept is simply the point with x = 0 (and the corresponding y value).
which is c, because
y = 0² + 8×0 + 7 = 7
the y-intercept = (0, 7)

Answers
The probability that Juliana will take jazz on Saturday morning based on the decision tree given is 3%.
What is the probability that jazz is taken on Saturday morning?The probability that jazz is taken is:
= 1 - Probability of ballet
= 1 - 70%
= 30%
The probability that if jazz is taken, it will be taken on Wednesday is:
= Probability that jazz is taken on Wednesday night / Probability that Jazz is taken
= 27% / 30%
= 90%
The probability that Jazz is taken on Saturday morning is therefore:
= Probability that jazz is taken x (1 - Probability of Wednesday night)
= 0.3 x ( 1 - 90%)

Answers
Answer:
14a + 6b
Step-by-step explanation:
To expand use distributive property. a*(b +c) =a*b +a *c
Simplifying an expression
2*(3a - 5b + 4*(a+2b) = 2*(3a -5b + 4*a +4*2b)
= 2*(3a - 5b + 4a + 8b)
= 2* (3a + 4a - 5b + 8b)
Combine like terms. To combine like terms, add or subtract the coefficient of the variables. 3a and 4a & (-5b) and 8b are like terms
= 2*( 7a + 3b)
= 2*7a + 2*3b
= 14a + 6b
Hey there!
2(3a - 5b) + 4(a + 2b)
= 2(3a - 5b) + 4(1a + 2b)
= 2(3a) + 2(-5b) + 4(1a) + 4(2b)
= 6a - 10b + 4a + 8b
= (6a + 4a) - (10b + 8b)
= 6a + 4a - 10b + 8b
= 10a - 2b
Therefore, your answer is: 10a - 2b

Answers
MN goes through
(2,3)(-3,2)Slope:-
m=2-3/-3-2=-1/-5=1/5Slope of perpendicular line:-
-5Passes through k(3,-3)
Equation in point slope form
y-y1=m(x-x1)y+3=-5(x-3)y+3=-5x+15y=-5x+12Check one by one
0=-5(-12)+12=60+12=722=-5(2)+12=-10+12=2Yes option B is correct
Answer:
(2, 2)
Step-by-step explanation:
First find the slope of the line MN, using the two given points:
[tex]\sf let\:(x_1,y_1)=(2,3)[/tex]
[tex]\sf let\:(x_2,y_2)=(-3,2)[/tex]
[tex]\implies \sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-3}{-3-2}=\dfrac15[/tex]
If two lines are perpendicular to each other, the product of their slopes will be -1.
Therefore, the slope (m) of the line perpendicular to MN is:
[tex]\implies \dfrac15 \times m=-1[/tex]
[tex]\implies m=-5[/tex]
Using the point-slope form of the linear equation with point K (3, -3), we can construct the linear equation of the line perpendicular to MN:
[tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-(-3)=-5(x-3)[/tex]
[tex]\implies \sf y=-5x+12[/tex]
Now we have the equation of the line perpendicular to MN, we can input the x-values of the solution options to see which once is correct:
[tex]x=0\implies \sf y=-5(0)+12=12\implies (0,12)[/tex]
[tex]x=2\implies \sf y=-5(2)+12=2\implies (2,2)[/tex]
[tex]x=4\implies \sf y=-5(4)+12=12\implies (4,-8)[/tex]
[tex]x=5\implies \sf y=-5(5)+12=-13\implies (5,-13)[/tex]
Therefore, the point that is on the line that is perpendicular to MN and passes through point K is (2, 2)
