what is F (x) = -x^2 - 10x f= (−5)
Answer:
75
Step-by-step explanation:
f(x)=-x^2-10x
f(-5)=(-5)^2-10(-5)
f(-5)=(-5)(-5)+50
f(-5)=25+50
f(-5)=75
4x - 3 = 2x + 7
Solve the equation
Answer:
x = 5
Step-by-step explanation:
4x - 3 = 2x + 7
Combine like terms:
4x - 2x = 2x
7 + 3 = 10
Set it up:
2x = 10
Divide:
x = 10 ÷ 2
Solve:
x = 5
solve for the variable. -2x + 6 = 14
Answer:
Step-by-step explanation:
-2x + 6 = 14
-2x = 8
x = -4
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
To solve for the variable x, we're going to isolate it.
First step is: Subtracting 6 by both sides:
[tex]-2x+6-6=14-6\\[/tex]
Notice how the +6 and the -6 cancel each other out. So we get:
[tex]-2x=8[/tex]
Second step is to divide both sides by -2:
[tex]\frac{-2}{-2} x=\frac{8}{-2}[/tex]
The -2's cancel each other out to:
[tex]x=-4[/tex]
find the value of each of the four remaining trigonometric functions
Answer:
tanФ = [tex]\frac{\sqrt{2}}{2}[/tex], cscФ = 3, secФ = [tex]\frac{3\sqrt{2} }{4}[/tex], cotФ = [tex]2\sqrt{2}[/tex]
Step-by-step explanation:
tanФ= [tex]\frac{1}{2\sqrt{2} } =\frac{2\sqrt{2}}{8} =\frac{\sqrt{2} }{2}[/tex]
cscФ= [tex]3[/tex]
secФ= [tex]\frac{3}{2\sqrt{2}} =\frac{6\sqrt{2}}{8} =\frac{3\sqrt{2}}{4}[/tex]

x²-12x+a=(x+b)² find a and b
Answer:
Step-by-step explanation:
x² - 12x + a = (x + b)²
x² - 12x + a = x² + 2xb + b²
-12 = 2b and a = b²
b = -6
a = b² = 36
The value of a is 36 and b = -6.
What is the quadratic equation?The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of: ax² + bx + c = 0.
The given expression is;
[tex]\rm x^2-12x+a=(x+b)^2[/tex]
The solution of the equation is determined in the folllowing steps given below.
[tex]\rm x^2-12x+a=(x+b)^2\\\\x^2-12x+a=x^2+2xb+b^2\\\\2xb + b^2 = a-12x[/tex]
On comparing the equation
[tex]\rm 2b =-12\\\\b =\dfrac{-12}{2}\\\\b=-6[/tex]
The value of a is;
[tex]\rm a=b^2\\\\b=-6\\\\a=(-6)^2\\\\a=36[/tex]
Hence, the value of a is 36 and b = -6.

Emma invested $750 in an account paying an interest rate of 1.9% compounded quarterly. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $910?
Answer:
10.2
Step-by-step explanation:
The B of years it took to the given principal to amount $910 is 3.4 years.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].
Given that, principal =$750, rate of interest =1.9% and amount=$910.
Let the number of years be x and compounded quarterly.
Here, 910=750(1+ 1.9/100)³ˣ
910/750 =(1+0.019)³ˣ
1.213=(1.019)³ˣ
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Exact Form:
x=ln(1.213)/3ln(1.019)
Decimal Form: 3.419
≈ 3.4 years
Therefore, the number of years it took to principal to reach $910 is 3.4 years.

In isosceles triangle WXY, XY is 13 inches in length and WY is 10 inches. What is the length of XZ? answer asap please
=============================================================
Explanation:
Notice the double tickmarks on segments WZ and ZY. This tells us the two segments are the same length. Let's say they are m units long, where m is a placeholder for a positive number.
That would mean m+m = 2m represents the length of segment WY, but that's equal to 10 as the diagram shows. We have 2m = 10 lead to m = 5 after dividing both sides by 2.
We've shown that WZ and ZY are 5 units long each. In short, we just cut that length of 10 in half.
-----------------------------------
Let's focus on triangle XYZ. This is a right triangle with legs XZ = unknown and ZY = 5. The hypotenuse is XY = 13.
We'll use the pythagorean theorem to find XZ
a^2 + b^2 = c^2
(XZ)^2 + (ZY)^2 = (XY)^2
(XZ)^2 + (5)^2 = (13)^2
(XZ)^2 + 25 = 169
(XZ)^2 = 169-25
(XZ)^2 = 144
XZ = sqrt(144)
XZ = 12
Segment XZ is 12 inches long.

. There are 258,890,850 number combinations possible in the Mega Millions lottery. One winning jackpot ticket will be chosen at random. Brent chooses his favorite number combination and buys one ticket. Find the probability Brent will win the jackpot. Round the decimal to the first digit that is not zero, then write the name of the decimal.
Answer:
0.000000004 = 4 hundred millionths probability Brent will win the jackpot.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
1 desired combination out of 258,890,850. So
[tex]p = \frac{1}{258890850} = 0.000000004[/tex]
9 places after the decimal point is hundred millionths
0.000000004 = 4 hundred millionths probability Brent will win the jackpot.

Describe the transformations of f(x) when compared to the parent function [y = x2].
f(x) = x2+5
The transformations of f(x) when compared to the parent function is the graph of [tex]f(x)=x^2+5[/tex] is moved 5 units up
Transformation of functions
Transformation of function is transforming a function from one form to another form .
Rules of transformation :f(x)-> f(x)+a , f(x) will be moved 'a' units up
f(x)-> f(x)-a , f(x) will be moved 'a' units down
f(x)-> f(x-a) , f(x) will be moved 'a' units right
f(x)-> f(x+a) , f(x) will be moved 'a' units left
f(x)-> -f(x), f(x) will be reflected across x-axis
f(x)-> f(-x), f(x) will be reflected across y-axis
For quadratic, the parent function is [tex]f(x)=x^2[/tex]
Given that [tex]f(x)=x^2+5[/tex]
Here , 5 is added with f(x) at the end
f(x)-> f(x)+a , f(x) will be moved 'a' units up
[tex]f(x)=x^2 ------ > f(x) =x^2+5[/tex]
The graph of f(x) will be move 5 units up
