The value
Pi /2
is a solution for the equation 2 sin^2 x- sin x-1=0.
O A. True
B. False
Answer:
A
Step-by-step explanation:
Check the solution by substituting x = [tex]\frac{\pi }{2}[/tex] into the left side of the equation
2sin²x - sinx - 1
= 2sin²([tex]\frac{\pi }{2}[/tex] ) - sin ([tex]\frac{\pi }{2}[/tex] ) - 1
= 2(1)² - 1 - 1
= 2 - 1 - 1
= 0
= right side
[tex]\frac{\pi }{2}[/tex] is therefore a solution to the equation

Which of the forms below is a pyramid?
Answer:
A
Step-by-step explanation:
The arc corresponding to a central angle of 35° in a circle of radius 10 feet messures___feet. Round your answer to two decimal places.
Answer:
6.11 ft
Step-by-step explanation:
s = (∅/360) * 2πr
s = (35/360) * 2π(10)
s = 6.108652382
Rounded
s = 6.11 ft
There's a piece of a pyramid is a rectangle with a width of 4.6 cm and the length of the 9 cm. What is the height in centimeters of the pyramid if it's volume is 82.8 cm^3
Answer:
6cm
Step-by-step explanation:
Given data
Width= 4.6cm
Length= 9cm
Volume= 82.8cm^3
The expression for the volume is given as
V= lwh/3
82.8= 9*4.6*h/3
cross multiply
82.8*3= 9*4.6*h
248.4= 41.4h
h= 248.4/41.4
h= 6cm
Rachel has two coupons for a bicycle.
Coupon A:
15% off of a $95 bicycle
$18 rebate on a $95 bicycle
Coupon B:
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Coupon A gives the lower price.
Х
The price with coupon A is $(less than the price with coupon B.
Coupon B gives the lower price.
The price with coupon B is $ less than the price with coupon A.
$
Answer: Coupon B gives the lower price
The price of coupon B is 3.75 dollars less than the price of coupon A.
======================================================
Explanation:
15% off means she saves 15% of the original price.
15% of 95 = 0.15*95 = 14.25
Rachel saves $14.25 if she goes with coupon A.
We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).
If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars
Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.

Sides of the rectangle are in the ratio 14:3. If the perimeter of the rectangle is 170cm. Find the length and breadth of the rectangle.
Answer:
length:70cm
breadth:15cm
Step-by-step explanation:
170cm÷2=85cm
85cm=14:3
14+3=17
85cm÷17=5cm
5cm×14=70cm
5cm×3=15cm

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on a certain object, the acceleration of the object is 7 /ms2. If the acceleration of the object becomes 2nd /ms2, what is the force?
Answer:
18 N
Step-by-step explanation:
Let F denote the force, m denote the mass of the object and a denote the acceleration of the object.
[tex]F=ma[/tex]
[tex]m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg[/tex]
[tex]F_{2} =ma_{2}=9*2=18N[/tex]
5x - y = -1 - -5x + 3y = 25
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4

how do i solve this?
Answer:
x= 15
Step-by-step explanation:
heyo, algebra is giving me a headache, help me with this pls?
Answer:
H: 41
Step-by-step explanation:
upfront charge = 36
each cone costs .52
sell price 1.40
(sell price - cone cost) * number of cones - upfront cost =0 to find where break even is
-36+(1.40-.52)*x=0
-36+.88x=0
.88x=36
x=40.90
need to round up to break even to 41
Answer:
Option C 41 is correct answer.
Given:
Cost of rent of the equipment = 36 $
Cost on ingredients of each cone = 0.52 $
Selling price of each cone = 1.40
To find:
Number of cones(let = x) joel must sell in order to make a profit?
1.40x > 36+ 0.52x
subtracting 0.52 x from both the side,
1.40x - 0.52x > 36
0.88x > 36
dividing both side by 0.88,
x > 36/0.88
x> 40.909090....~ 41
Option C 41 is correct answer.

A sequence is defined recursively by the formula f(n + 1) = –2f(n). The first term of the sequence is –1.5. What is the next term in the sequence?
–3.5
–3
0.5
3
Answer:
The answer is 3
Step-by-step explanation:
It's just wisdom I mean think about it it
1.5 then 3
⭐ Initially, we have to find the reason why it was -1.5:
[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]
➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.
[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]
⌛ So, we will have to find what x is worth in this case:
[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]
[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]
→ Knowing this...
[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]
[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex] [tex]\checkmark[/tex]

Solve for x in 12x + 4y = 16
Answer:
y = -3x+ 4
one equation two unknows can not solve uniquely
4y = -12x + 16
y = -3x+ 4
is the solution set
Step-by-step explanation:
Answer:
[tex]x = \frac{ 16 - 4y}{12}[/tex]
Step-by-step explanation:
12x + 4y = 16
12x + 4y - 4y = 16 - 4y
12x = 16 - 4y
[tex]\frac{12x}{12} = \frac{ 16 - 4y}{12}[/tex]
[tex]x = \frac{ 16 - 4y}{12}[/tex]
