Help I do not know how to do this!
Step-by-step explanation:
this is one of the formulas you should remember for life :
the general solution for a quadratic equation
ax² + bx + c = 0
is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case that is
x = (-4 ± sqrt(4² - 4×1×-1))/(2×1) = (-4 ± sqrt(16 + 4))/2 =
= (-4 ± sqrt(20))/2 = (-4 ± sqrt(4×5))/2 =
= (-4 ± 2×sqrt(5))/2 = -2 ± sqrt(5)
x1 = -2 + sqrt(5) = 0.236067977...
x2 = -2 - sqrt(5) = -4.236067977...
so, the negative solution is the x2 solution :
-4.236067977...

Answer:
16°
Step-by-step explanation:
The trig function tangent relates an acute angle of a right triangle to the measures of the adjacent and opposites sides. Those are the sides given here, so the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(?) = 14/49 = 2/7
When the tangent of the angle is known, the inverse tangent function can be used to find the angle:
? = arctan(2/7) ≈ 16°
The value of "?" is about 16°.

05) A polynomial function f of degree(6) whose coefficients are real numbers has the zeros i, 4-i,2+i . Find the remaining zeros of (f)
The degree of the polynomial function f is the number of zeros function f has.
The remaining zeros of the polynomial function are -i, 4 + i and 2 - i
How to determine the remaining zerosThe degrees of the polynomial is given as;
Degree = 6
The zeros are given as:
i, 4-i,2+i
The above numbers are complex numbers.
This means that, their conjugates are also zeros of the polynomial
Their conjugates are -i, 4 + i and 2 - i
Hence, the remaining zeros of the polynomial function are -i, 4 + i and 2 - i

Given the similar pyramids pictured below.
The volume of pyramid 1 is 675 cm3 and its surface area is 504 cm2 If the volume of pyramid 2 is 3125 cm3 , what is its
surface area?
Answer:
1400 cm²
Step-by-step explanation:
The ratio of volumes of similar figures is the cube of the scale factor. Here, that is 3125/675 = sf³. That means the scale factor is ∛(3125/675) = 5/3.
The ratio of areas of similar figures is the square of the scale factor. Here, that is (5/3)² = 25/9.
The area of the larger pyramid is 25/9 times the area of the smaller one:
A = (25/9) × 504 cm² = 1400 cm²
The surface area of pyramid 2 is 1400 cm².
_____
Additional comment
You don't need to find the scale factor. You can jump directly to the fact that the surface area multiplier is the 2/3 power of the volume ratio.

[tex]y=mx+b[/tex]
Answer:

We divide both sides by m (as long as [tex]m\ne0[/tex]) and read right to left.

TOPIC: Compound Probability
Bernardo Flips a coin and rolls a 1-6 number cube. Draw a tree diagram to show the set of all possible outcomes.
Answer:
There are a total of twelve possible outcomes. This is because flipping a coin has two possible outcomes (either heads or tails) and rolling a number cube has 6 of them (1-6) so 2 times 6 is 12.
If you want to draw a tree diagram, first split your tree into two branches, one for heads and one for tails. Then, split both branches into 6 sub-branches each, so each branch has a full set of numbers from 1-6.
Or you can do it the other way around, first split your tree into 6 branches, then split all branches into 2 sub-branches each.

Answer:
A = P (1 + i)^n A is the final amount
P is the initial amount
i = interest / period
n = number of periods
A = 315 * (1 + .015)^1.5 = 322.11

Answer:
1) The error is 3x² - 3x - 18 = 3(x² - 3x - 18)
The 3 needs to be factorised out of each term in the brackets not just 3x² → the correction is 3x² - 3x - 18 = 3(x² - x - 6) → 3(x - 3)(x + 2)
2) The 5 and 1 are written in the wrong brackets; it should be (10x - 1)(x + 5)

Convert the mixed number 5 4/9 to an improper fraction.
Answer:
[tex]=\frac{49}{9}[/tex]
Step-by-step explanation:
Given the following question:
[tex]5\frac{4}{9}[/tex]
In order to convert a mixed number into an improper fraction, you have to multiply the denominator by the whole number (in this case; 9 and 5) and then add the numerator (in this case; 4) to receive your answer. Of course, keeping the denominator the same.
[tex]5\frac{4}{9}[/tex]
[tex]5\frac{4}{9}=9\times5=45+4=49=\frac{49}{9}[/tex]
[tex]=\frac{49}{9}[/tex]
Hope this helps.
The improper fraction for the given mixed fraction is 49/9.
The given fraction is [tex]5\frac{4}{9}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as [tex]a\frac{b}{c}=\frac{(a\times c)+b}{c}[/tex]
Now, [tex]5\frac{4}{9}=\frac{(5\times9)+4}{9}[/tex]
= (45+4)/9
= 49/9
Therefore, the improper fraction for the given mixed fraction is 49/9.

A karate studio charges $35 for the first course and $22. 50 for each course after that, even if the student leaves the course early. Cena paid $170 for her son to take courses. How many courses did he take? 6 courses 7 courses 8 courses 10 courses.
The Cena can take 7 courses
We have given that the karate charges $35 for the first course and $22.50 for each course after that. Our total is $170.
What is the condition we can write here?[tex]22.50x + 35 = 170[/tex]
for solving this linear equation
First, subtract 35 from both sides.
[tex]22.50x = 135[/tex]
isolate x so divide both sides by 22.50.
[tex]x=\frac{135}{22.50}[/tex]
Therefore we get x = 6
Remember to add the additional class, so x is actually 7.
So,the Cena can take 7 courses.

PLEASE HELP ME????( Brainlest) Please Show Work???
Step-by-step explanation:
again, 2 unknowns.
x = number of 2- points baskets
y = number of 3- points baskets
we know they hit the basket 37 times in a so far unknown mixture of 2-point and 3- point throws.
x + y = 37
which gives us e.g.
x = 37 - y
and we know that with this unknown mixture they scored 80 points.
so,
2x + 3y = 80
as every successful 2-points throw scores 2 points, and every successful 3-points throw scores 3 points.
so, again our 2 equations :
x = 37 - y
2x + 3y = 80
remember, we prepared the first equation so that it gives us already an identity expressing one variable by the other. and that we use in the second equation :
2×(37 - y) + 3y = 80
74 - 2y + 3y = 80
74 + y = 80
y = 6
and from
x = 37 - y
we get
x = 37 - 6 = 31
so, they had 31 2-points throws and 6 3-points throws.
If the simple interest on $3,000 for 8 years is $1,200, then what is the interest rate?
Answer:
i THINK its 18.75% per year
Step-by-step explanation:
r = (1/8)((3,000/1200) - 1 ) = 0.1875
r = 0.1875 * 100 = 18.75
