AB = ?
does anyone know?
Answer:
AB = 6.97 (nearest hundredth)
Step-by-step explanation:
Sine Trigonometric Ratio
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = 35°O = AC = 4 unitsH = ABSubstitute the given values and solve for AB:
[tex]\implies \sf \sin(\theta)=\dfrac{O}{H}[/tex]
[tex]\implies \sf \sin(35^{\circ})=\dfrac{4}{AB}[/tex]
[tex]\implies \sf AB=\dfrac{4}{\sin(35^{\circ})}[/tex]
[tex]\implies \sf AB=6.973787182...[/tex]
Therefore, AB = 6.97 (nearest hundredth)

How do you convert this parabola equation: -7(x-7)^2 = (y-6) into standard form?
Answer:
y=−7x2+98x−337 is the answer
Please, I require assistance
Answer:
see explanation
Step-by-step explanation:
(a)
given 2 intersecting chords in a circle, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
FH × HG = DH × HE ( substitute values )
2y = 3 × 4 = 12 ( divide both sides by 2 )
y = 6
then
DE = 3 + 4 = 7
FG = 2 + y = 2 + 6 = 8
(b)
given 2 secants from an external point to a circle, then the product of one secant's external part and the entire secant is equal to the product of the other secant's external part and the entire secant , that is
AB × AC = AD × AE ( substitute values )
5(5 + x) = 6 × (6 + 6)
25 + 5x = 6 × 12 = 72 ( subtract 25 from both sides )
5x = 47 ( divide both sides by 5 )
x = 9.4
then
AE = 6 + 6 = 12
AC = 5 + x = 5 + 9.4 = 14.4
what is the slope of the line 6x+5y=10 ?
Answer:
[tex]-\dfrac 65[/tex]
Step-by-step explanation:
[tex]~~~~~~~6x +5y = 10\\\\\implies 5y = 10-6x\\\\\implies y = \dfrac 15(10-6x)\\\\\implies y=-\dfrac65x+2\\\\\text{It is now in slope-intercept form(y=mx+c), where m is the slope.}\\ \\\text{Hence,}~ m = -\dfrac 65[/tex]
Click “show your work” and graph the absolute value function shown below. f(x) =|x – 4| + 1
Answer: here u go
Step-by-step explanation:
Which of the following is true?
A. Since the slope of AD equals the slope of CB and the slope of DB equals the slope of CA, the
figure is a rectangle.
B. Since both pairs of opposite sides are of equal length, the figure is á square
C. Since AB=CD= 141, the figure is a rectangle.
D. Since AB=CD= 141, the figure is a square.
Answer:
C. Since AB = CD = √41, the figure is a rectangle.
Explanation:
All of them AD, CB, DB, CA have a slope of 0.
Here measure the length units, 5 units horizontal and 4 units vertical. Thus we can conclude it is a rectangle.
Find diagonal Length:
√(x2-x1)² + (y2-y1) = Length from points measure.√(5-0)² + (4-0)² [insert following coordinates]√25 + 16 [simplify]√41 [final answer]Since AB = CD = √41, the figure is a rectangle.
Calculate the area of ABC
There's a mistake in the picture - AC is 5cm too

Please help if you know!
Answer:
2.5 cups
Step-by-step explanation:
[tex]\frac{2}{12} =\frac{x}{15}[/tex] (x is the amount of cups of zucchini you will need to feed 15 people)
This proportion is showing that 2 cups of zucchini can feed 12 people, and we will use it to find how much zucchini we will need to feed 15 people.
Cross multiply
30 = 12x
divide both sides by 12 to isolate x
[tex]\frac{30}{12}[/tex] = x
2.5 = x

(r^-7)^6 im looking for anwser
Answer:
( r^-7 )^6 = r^-42 ( in exponential form )
( or )
1 / r^42 ( in fractional form )
Step-by-step explanation:
( r^-7 )^6
Formula : -
( a^m )^n = a^( mn )
Here,
a = r
m = - 7
r = 6
mn
= - 7 * 6
= - 42
Hence,
( r^-7 )^6 = r^-42 ( in exponential form )
( or )
( r^-7 )^6 = 1 / r^42 ( in fractional form )

SAT~GRE
Answer:
Step-by-step explanation:
Brian is a software salesman. His base salary is 1900 , and he makes an additional 40 for every copy of Math is Fun he sells. Let N represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating to p to n . Then use this equation to find his total pay if he sells 21 copies of Math is Fun.
Answer:
2740 is your total; p = 40n + 1900 is your equation.
Step-by-step explanation:
"p" represents total pay; "n" represents the number of copies he sells.
Base salary is 1900, and each copy sold gives him an extra 40
p = 40n + 1900 is your equation.
If he sells 21 copies. Plug in 21 for n
p = 40n + 1900
p = 40(21) + 1900
Simplify. Remember to follow PEMDAS. First, multiply, then add.
p = 40(21) + 1900
p = 840 + 1900
p = 2740

solve for x in this proportion.
x/4=6/8
Answer:
x = 3
Step-by-step explanation:
x / 4 = 6 / 8
4 time 2 = 8
4a = 8 divided both side by 4 4a / 4 = 8 / 4 a = 2
so
x time 2 = 6
2a = 6 divided both side by 2 2a / 2 = 6 / 2 a = 3

What is the mean, median, mode, and range of the
following data set? Be sure to label which
measurement you are referring to.
7,9,6,9, 7, 4,7
Answer:
if im not wrong all answers are 7
Step-by-step explanation:
if you add all the numbers u get 49 and if u divide by 7 cuz u have seven numbers. you should get 7 thats you mean. then for median if u put them from least to greatest ur middle number would still be seven and then your mode would be seven since seven shows up the most.

Choose the values that would complete the general solution for y= arctan (0.7002).
(blank)+360k degrees
-215
-35
-145
-325
Answer:
-145°, -325°
Step-by-step explanation:
The principal value of the arctangent of 0.7002 is 35°. The tangent function is periodic with a period of 180°, so the general solution is ...
y = (35 +180k) degrees . . . . . where k is an integer
Values from the given list include ...
-145°
-325°
_____
Additional comment
+35° and +215° would also be part of the general solution
