Answer:
x = 3/2; x = -1/2
Step-by-step explanation:
6x² - x - 2 = 0
⇔ 6x² - 4x + 3x - 2 = 0
⇔ (6x² - 4x) + (3x - 2) = 0
⇔ 2x(3x - 2) + (3x - 2) = 0
⇔ (3x - 2)(2x + 1) = 0
⇔[tex]\left \{ {{3x - 2=0} \atop {2x + 1=0}} \right.[/tex]
⇔[tex]\left \{ {{3x=2} \atop {2x=-1}} \right.[/tex]
⇔[tex]\left \{ {{x=2/3} \atop {x=-1/2}} \right.[/tex]
Blake has 864 square inches of material with which to create a hollow three-dimensional container. He decides to make either a cube or a sphere.
Which solid would have the greater volume? What is the greatest volume he can achieve with this amount of material?
Answer:
I think it's a cube, because the cube has bigger spaces because of the edges, but I don't know how much...

Answer:
n = - [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n
Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions
4(1 + n) = - 3n ← distribute left side
4 + 4n = - 3n ( add 3n to both sides )
4 + 7n = 0 ( subtract 4 from both sides )
7n = - 4 ( divide both sides by 7 )
n = - [tex]\frac{4}{7}[/tex]

C. 30°
D. 12°
can somone help plz i need help
Answer:
about 7.3 units
Step-by-step explanation:
to find the answer you do Pythagorean theorem
so you have (-9, -4) and (-2, -6)
you do X1-X2 and Y1-Y2
so -4-(6)=2
and -9-(-2)= -7
now you do a^2 + b^2 = C^2
so 2^2 + -7^2 = C^2
which is 4 + 49= C^2
53=C^2
√53=7.3
so 7.3 units :)

What is the domain of the function Y = tan(x/8)?
Oall real numbers except 4pi+4npi where n is any integer
Oall real numbers except 4pi+8npi where n any integer
Oall real numbers except 8pi+4npi, where n is any integer
Oall real numbers except 8pi+8npi, where n is any integer
Answer:
B) all real numbers expect 4pi+8pi where n is any integer
Step-by-step explanation:
The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.
What is the domain of a function?The domain is the set that contains all possible input values for the function.
Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
π/2 + nπ
Hence, let a composite tangent function , the domain is given by:
f(x) does not equal to π/2 + nπ
we have that , hence the domain is:
all real numbers except 4π+8nπ
All real numbers except 4π+8nπ, where n is any integer.

Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail
Answer:
The magnitude of the resultant force is: 27.40 pounds
Step-by-step explanation:
Given
[tex]F_1 = 45[/tex]
[tex]F_2 = 50[/tex]
[tex]\theta = 33[/tex]
Required
The magnitude of the resultant vector
To do this, we apply cosine formula
[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]
This gives:
[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]
[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]
[tex]R^2 = 2025+ 2500 - 3774.15[/tex]
[tex]R^2 = 750.85[/tex]
Take square roots of both sides
[tex]R = \sqrt{750.85\\[/tex]
[tex]R = 27.40[/tex]

Mark estimated that he would spend $300 of his paycheck on seven items that cost $50 each. Why is this not reasonable?
A. It is not reasonable because seven items could not all cost $50.
B. It is not reasonable because seven items at $50 each, would cost a total of $350.
C. It is not reasonable because seven items at $50 each would only cost $420.
D. It is not reasonable because he would have too much money left over.
Write an algebraic expression for the following:
5 less than twice a number
5 less would be -5
twice a number would be *2

Step-by-step explanation:
let assume the number is x:
Therefore 2x - 5

Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]
[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]
[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]

Step-by-step explanation:
A Diginacci sequence is created as follows.
• The first two terms are any positive whole numbers.
• Each of the remaining terms is the sum of the digits of the previous
two terms.
For example, starting with 5 and 8 the Diginacci sequence is
5, 8, 13, 12, 7, 10,...
The calculations for this example are
5+ 8 = 13, 8 + 1 + 3 = 12, 1+ 3 +1+ 2 = 7,1 + 2 + 7 = 10.
a) List the first 26 terms of the Diginacci sequence above.
b) Find, with explanation, two starting terms for a Diginacci sequence
so that its 2021st term is 11.
C) Find, with explanation, a Diginacci sequence that has no term equal
to 11
d) Find, with explanation, a sequence with two different starting terms
which contains five consecutive terms that are even and not all identical
a)
Answer:
5, 8, 13, 12, 7, 10, 8, 9, 17, 17, 16, 15, 13, 10, 5, 6, 11, 8, 10, 9, 10, 10, 2, 3, 5, 8
Explanation:
Diginacci Sequence
5+8=13, 8+1=9, 1+3+1+2=7, 1+2+7=10, 7+1+0=8, 1+0+8=9, 8+9=17, 9+1+7=17

F is inversely proportional to d^2.
When F = 5, d = 9
Work out d (positive value rounded to 2 DP) when F = 3
Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
Answer:
11.62
Step-by-step explanation:
F is inversely proportional to d^2, so
[tex]F=\frac{k}{d^2}[/tex]
for some constant k. To find k plug in given values for F and d.
[tex]5=\frac{k}{9^2}\\5=\frac{k}{81}\\k=405[/tex]
Now you can find d for F = 3.
[tex]3=\frac{405}{d^2}\\\\3d^2=405\\\\d^2=135\\d=\sqrt{135}\approx 11.62[/tex]

There are two angles given.
One is 90 and the other is 45.
90+45=135
180-135=45°
This proves that the triangle is isosceles.
This means that two angles are equal, but also two side lengths are the same.
In this triangle, the equal sides are CB and AC.
Therefore, AC is equal to 9.
