Answer:
see explanation
Step-by-step explanation:
∠ PQX = 90° ( angle in a semicircle )
∠ PXQ = 42° ( alternate angle theorem )
Angle between tangent and diameter is right, thus
∠ XPQ = 90° - 42° = 48°

Answer:
X-intercept- ( 3/7,0)
Y-intercept- (0,-3)
Step-by-step explanation:
To find the y-intercept(s), substitute in 0 for x and slove for y
y=7(0)-3
simplify y=-3
to find the x-intercept(s), substitute in 0 for y and slove for X
0=7x-3
rewrite equation- 7x-3=0 and slove
which would equal 3/7
Help please!Find the y-intercept of the line on the graph.

A measuring tape measures distance to
2.0
or 0.5, of an inch. Which is
the most appropriate way to report a length measured using this
measuring tape?
A. 12.5 inches
B.12.49936 inches
C.13 inches
D. 12.49 inches
A
because with b you would be able to get that close of a measurement with a measuring tape c you don't round up that high and D is also too close to 12.5 to not round up

Answer:
x = 7 or x = -8
Step-by-step explanation:
3|2x + 1| = 45
Divide both sides by 3.
|2x + 1| = 15
Separate into a compound equation.
2x + 1 = 15 or 2x + 1 = -15
2x = 14 or 2x = -16
x = 7 or x = -8
Answer: A

Saturday morning, 55% of the customers at The Gap spent over $50. If there were 300 customers at The Gap that morning, how many of them spent more than $500 ?
Answer:
165 customers spent more than $500.
Step-by-step explanation:
If you ment to put $500 for both, then you have to multiply 300 by 55%. This will give you 55% of 300 which is the amount of people that spent more than $500. You multiply them to get your answer.

Zayd can row 3/8 of a mile in 1/4 of an hour. What is the unit rate the describes the miles per hour?
Answer:
1.5mph
Step-by-step explanation:
Given parameters:
Distance sailed = [tex]\frac{3}{8}[/tex]miles
Time taken = [tex]\frac{1}{4}[/tex]hr
Unknown:
Unit rate of sail in miles hour = ?
Solution:
This is also the speed of the sail. It is the distance divided by time taken.
Speed = [tex]\frac{distance}{time}[/tex]
Speed = [tex]\frac{\frac{3}{8} }{\frac{1}{4} }[/tex]
Speed = [tex]\frac{3}{8}[/tex] x 4 = 1.5mph

Solve for the value of y.
Answer:
y=6
Step-by-step explanation:
add both expressions together. 14y+6. Then set this equal to 90, because this is a 90 degree angle. Solve for y. 84=14y. y=6
Step-by-step explanation:
90= 6y+5+8y+1
14y=84
y=6

If triangle ABD similar to triangle EFG , find BC and FH. Options are in the picture ^^
Answer:
B. BC=12, FH=9
Step-by-step explanation:
no clue tbh but it worked
plz help on this one
Answer:
60°
Step-by-step explanation:
Because of the rule that all triangle's angles must measure to 180°.
So I did...
60+60=120
180-120= 60
Answer
60 degrees
Step-by-step explanation:
A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.
Please help me, please

[tex] - 5 \: \: and \: \: 3[/tex]
Look :
[tex] - 5 + 3 = - 2[/tex]
[tex] - 5 \times 3 = - 15[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
-5 and 3
Step-by-step explanation:
because -5 + 3 = -2 and -5 X 3 = -15.
-5 is bigger in -5 + 3 so your answer would be negative.
and for the multiplication on use the sleeping dog - - + you have a negative and a positive so the answer would be negative.
the equation of the line that has a slope of
-23 that passes through the point (5, 1). Which form did you choose to write the equation in and why?
Answer:
I used the y=Mx+b equation because it has a good job showing each of the elements in the equation.
Step-by-step explanation:
The slope is -2/3 so if you add it to (5,1) it would be (3,4) as you just add three and subtract to to the point. I’m going to use for this equation as it is more simple and it gives a good job showing what each element is in the equation. M is the slope, so now we have y= -2/3x +b. To find b, substitute x and y for a point on this line which I will use the point (3,4) for. Now, multiply -2/3 by 3 and you will get -2 after. Now you have 4=-2+b which the answer would be 6.
This is just an example of finding the equation, which form I used, and why.
Find at least one solution to the following equation:
sin(x
2 − 1)
1 − sin(x
2 − 1) = sin(x) + sin2
(x) + sin3
(x) + sin4
(x) + · · ·
For |x| < 1, we have
[tex]1+x+x^2+\cdots=\displaystyle\sum_{n\ge0}x^n=\frac1{1-x}[/tex]
We have |sin(x)| ≤ 1, with equality when x = ± π/2. For either of these, the right side of the equation does not converge, since it's either an infinite sum of 1s or an infinite alternating sum of 1 and -1.
So for |sin(x)| < 1, we have
[tex]\sin(x)+\sin^2(x)+\sin^3(x)+\cdots=\dfrac1{1-\sin(x)}-1=\dfrac{\sin(x)}{1-\sin(x)}[/tex]
so the equation is equivalent to
[tex]\dfrac{\sin(x^2-1)}{1-\sin(x^2-1)}=\dfrac{\sin(x)}{1-\sin(x)}[/tex]
One obvious set of solutions occurs when x = x² - 1 :
x² - x - 1 = 0 → x = (1 ± √(5))/2
i.e. the golden ratio φ ≈ 1.618 and 1 - φ ≈ 0.618.
