Step-by-step explanation:
BALTIMORE It was not an overt incident of racism that prompted Edray Goins, an African-American mathematician in the prime of his career, to abandon his tenured position on the faculty of a major research university last year.
The hostilities he perceived were subtle, the signs of disrespect unsp_ken.
And at the recent math meeting, where Dr. Goins delivered a keynote address titled “A Dream Deferred: 50 Years of Bl_cks in Mathematics,” his presence kindled conversations about racial slights in the math world. The presumption of competence and authority that seems to be automatically acc0rded other mathematicians, for instance, is often not applied to them, several bl_ck mathematicians said.

Answer:
[tex] r = 6\sqrt{3} [/tex]
Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]
Multiply both sides by 36
[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]
[tex] 540 \pi = 5\pi * r^2[/tex]
Divide both sides by 5π
[tex] \frac{540 \pi}{5\pi} = \frac{5\pi * r^2}{5\pi} [/tex]
[tex] 108 = r^2 [/tex]
[tex] r = \sqrt{108} [/tex]
[tex] r = \sqrt{36*3} [/tex]
[tex] r = 6\sqrt{3} [/tex]

b. Triangle ABC is similar to triangle EBD. Find the lengths of segments BD and BE. Show all your work.
Answer:
BD=4/3 BE=5/3
Step-by-step explanation:
by pythag theorem we can see that AC=3 and because CPCTC
AC/DE=AB/EB=CB/DB we can see that CB/DB=3/1 and CB is 4 therefore DB = 4/3 do same with BE and we get solution above.
Find the value of x please help
Find the value of c so that (x+3) is a factor of the polynomial p(x). p(x)=x^3-4x^2+cx+33
Answer:
The value of c is -10.
Step-by-step explanation:
Since (x+3) is a factor of the polynomial p(x).
We have that:
x + 3 = 0 -> x = -3
So p(-3) = 0
Then
[tex]p(x) = x^3 - 4x^2 + cx + 33[/tex]
[tex](-3)^3 - 4(-3)^2 - 3c + 33 = 0[/tex]
[tex]-27 - 36 - 3c + 33 = 0[/tex]
[tex]3c = -30[/tex]
[tex]c = -\frac{30}{3}[/tex]
[tex]c = -10[/tex]
The value of c is -10.
Only answer please because Due now.
Answer:
B. Not enough information.
Step-by-step explanation:
We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.
AAA is not a criterion that proves two triangles are congruent.
Therefore, we will conclude that there is not enough information.
How much money needa to be deposited now into an account to obtain 9,000 in 7 years if the interest rate is 8% per year compounded continuously?
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160

The Royals softball team won 55 games and lost 25 games. What percent of the games did they lose? Round to the nearest whole percent.
_______% games lost
Answer:
31% games lost.
Step-by-step explanation:
Given that the Royals softball team won 55 games and lost 25 games, the following calculation must be performed to determine the percentage of games they lost out of the total games played:
55 + 25 = 80
80 = 100
25 = X
(25 x 100) / 80 = X
2,500 / 80 = X
31.25 = X
Thus, rounded to the nearest percentage, the Royals lost 31 percent of their games.

A pair of basketball shoes was originally priced at $80, but was marked up 37.5%.
What is the new price of the shoes after the mark up?
Answer:
110
Explanation:
First move the decimal point over to the left twice.
.375
Then multiply 80 by .375 like this :
.375 x 80 = 30
Lastly, add 30 to 80 and put the dollar sign.
$110

2) I believe that this is false. The amount of interest is the amount of extra money that has to be paid (total interest). The interest rate is how you calculate that.
3) true, because decimal equations are simpler.
When using substitution to solve this system of equations, what is the result of the first step?
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Hope this helps you
Answer:
Solve. Because now you have only one variable.

Fill in the blanks below in order to justify whether or not the mapping
shown represents a function.
first bank says , the mapping diagram above { represents } or does { NOT represent } a function since ..
blank 2 says { for each number } or { there is one number }
blank 3 says { set a the output } or { set b the input } or { set a the input } , and { set b the output } !
1) it's a function 2) for each number 3) set a input and set b output
to be a function, no ordered pairs should have same first coordinate, hence this is a function
