Solve the equation for all real solutions in simplest form.
3z^2+17z+16=0
Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Determine the ratio of shaded sections to striped sections. Then explain its meaning.
Answer:
Determine the ratio of shaded sections to the total number of sections. Write the ratio as a fraction in simplest form and as a decimal.
Answer:
3/8
Step-by-step explanation:
Total no. of sections= 8
No. of shaded sections= 3
Therefore, the ratio = 3/8

There is an ample supply of identical blocks (as shown). Each block is constructed from four 1 × 1 × 1 unit-cubes glued whole-face to whole-face. What is the greatest number of such blocks that can be packed into a box that is 6 units tall, 7 units wide, and 8 units deep without exceeding the height of the box?
Answer:
72
Step-by-step explanation:
The answer is 72 because my teacher gave it to me. I promise i'm legit, and I won't lie. This is the real answer, and if you choose 336, you're probably getting it wrong. That's from Math Olympiad.
A trapezoid has a base 1 = 6 base = 8 and a height = 3 whats the area?
Answer:
[tex]area = 21[/tex]
Step-by-step explanation:
Area of trapezoid formula:
[tex]area = \frac{a + b}{2} h[/tex]
Given information:
a: 6
b: 8
h: 3
Using the given information,
[tex]area = \frac{6 + 8}{2} 3[/tex]
Add the numbers in the numerator
[tex]area = \frac{14}{2} 3[/tex]
Reduce fraction with 2
[tex]area = 7 \times 3[/tex]
Answer:
[tex]area = 21[/tex]

12 out of the 50 U.S. states have names that start with a vowel. What percentage of U.S. states' names start with a vowel
Answer:
24% of the U.S. states have names that start with vowels
Step-by-step explanation:
12 ÷ 50 = 0.24
0.24 × 100 = 24%
Answer:
24 % of the U.S. states' names start with a vowel
Step-by-step explanation:
12 out of 50 vcan be written in math terms as;
12 / 50 which equals the decimal form of a percent as shown;
12 / 50 = 0.24
which in percent form is: 24 %
What does b stand for 11.3 > b/4.3
Answer:
b = 45.69
Step-by-step explanation:
5 x 5 = 25
25 x 2 & and a half = 45.69
In the inequality expression "11.3 > b/4.3," the variable "b" represents an unknown numerical value.
In the inequality 11.3 > b/4.3, b is the variable.
The inequality is stating that 11.3 is greater than the result of dividing "b" by 4.3.
The purpose of the inequality is to compare the value of 11.3 with the value of "b/4.3" and determine if 11.3 is greater or not.
The variable "b" can take any value that satisfies the inequality.
Hence, in the inequality b stands for unknown value or variable.

Consider function fand function g.
() = In
g(x) = -5 In
How does the graph of function g compare with the graph of function ?
Unlike the graph of function f, the graph of function ghas a y-intercept.
The graph of function g is the graph of function fvertically stretched by a factor of 5.
Unlike the graph of function f, the graph of function g decreases as x increases.
The graphs of both functions have a vertical asymptote of r = 0.
Unlike the graph of function f, the graph of function g has a domain of {+1 -5 < x < 0}

Answer:
I believe it is the first third and fourth options, I am not entirely sure for I mostly guessed on them, but they make the most sense when looking at the graph.
Step-by-step explanation:
It can be deduced that the graph of function f and g compare as:
Unlike the graph of function f, the graph of function g decreases as x increases.The graph of both functions have a vertical asymptote of x = 0.What is a function?A function in mathematics simply means the relation between a set of inputs and a set of permissible outputs.
In this case, the graph of both functions have a vertical asymptote of x = 0. This is because the divisor equals to zero for a value of x.

Would y^10/y^10 become 1?
Answer:
yes
Step-by-step explanation:
If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y
If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y

3) Reflexive Property
4) SAS
Step-by-step explanation:
ST ≅ TS1. The Reflexive Property states that: a quantity is congruent (equal) to itself.
Example: a = a In this case, it could be seen as ST ≅ ST because they have/are the same side(s).RST ≅ UTS1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.
Example: RST ≅ UTS (both have S and T) Can be seen as RST ≅ UST as well to make their similarity more evident.2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

3х - 7y = -3
Answer:
wrong
Step-by-step explanation:
-5x + 3y, you can’t add those together since they aren’t like numbers
3x - 7y, can’t be done either since again, they aren’t like numbers.
like numbers include the same variable or no variable, which means you cant do -5x + 3y but you can to -5x + 3x. you can add those together since both of the numbers have the variable “x” while 3y and 7y have the same variable “y” therefore those can be added together.
since there isn’t a way to add those, both of those answers are not only wrong, but they’re also in simplest form.
