The measure of angle that is coterminal with 425° is 425° + (1440n)°
What are coterminal angles?Coterminal angles are angles in multiples of the angles in standard positions examples(360°).
It is mostly gotten by adding 360° or multiples of 360 to the angle.
One of the unique behavior of coterminal angles is that their sine, cosine and tangent are equal.
Analysis:
From the options, the only one with an addition of 360 or multiples of 360 is 425 + 1440n
If we put n = 1, the coterminal angle gotten is 1865.
if we find the sine of 425°, we get 0.9063 which is same as the sine of 1865°.
In conclusion, the coterminal angle to 425° is 425° + (1440n)°.

Solve the equation by factoring. 8x^2+10x-7=0
What is the solution set?
Answer:
[tex]x = - \frac{7}{4} \: \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]8 {x}^{2} + 14x - 4x - 7 = 0 \\ 2x(4x + 7) - (4x + 7) = 0 \\ (4x + 7)(2x - 1) = 0[/tex]
Answer:
[tex]\large \text{$x_1$}=-\dfrac{7}{4}, \large \text{$x_2$}=\dfrac{1}{2}[/tex]
Step-by-step explanation:
Given: 8x² + 10x - 7 = 0
When factoring trinomials of the form ax² + bx + c:
multiply the leading coefficient and the last term.find the product factors that add to give you the coefficient of the middle term.rewrite the polynomial with those factors replacing the middle term.1. Split the middle term:
⇒ 8 × -7 = -56 [multiply the leading coefficient and the last term]
⇒ 14, -4 [find the product factors that add to the middle term's coefficient]
⇒ 8x² + 14x - 4x - 7 = 0 [rewrite with those factors replacing the middle term.]
2. Factor by grouping:
⇒ 8x² + 14x - 4x - 7 = 0 [factor out 2x]
⇒ 2x(4x + 7) - 4x - 7 = 0 [factor out -1 or the negative sign]
⇒ 2x(4x + 7) -1(4x + 7) = 0 [factor out 4x + 7]
⟹ (4x + 7)(2x - 1) = 0
3. Separate into 2 cases:
4x + 7 = 02x - 1 = 0
Case 1:
⇒ 4x + 7 = 0 [subtract 7 from both sides]
⇒ 4x + 7 - 7 = 0 - 7
⇒ 4x = -7 [divide both sides by 4]
⇒ 4x ÷ 4 = -7 ÷ 4
⟹ x = [tex]\bold{-\dfrac{7}{4}}[/tex]
Case 2:
⇒ 2x - 1 = 0 [subtract 1 from both sides]
⇒ 2x - 1 + 1 = 0 + 1
⇒ 2x = 1 [divide both sides by 2]
⇒ 2x ÷ 2 = 1 ÷ 2
⟹ x = [tex]\bold{\dfrac{1}{2}}[/tex]
Solutions:
[tex]\large \text{$x_1$}=-\dfrac{7}{4}, \large \text{$x_2$}=\dfrac{1}{2}[/tex]

Answer:
3/4
Step-by-step explanation:
Scale factor is the ratio between two different triangles. They can be scaled if they are similar triangles, which they are (in this case). Since we know that these two triangles are similar, we want to match all the sides up in a way where they all have the same ratio.
NK=3 and AH = 4, so NK/AH = 3/4.
GK=6 and LH = 8, so GK/LH = 6/8 = 3/4.
GN = 15 and LA = 20, so GN/LA = 15/20 = 3/4.
We found the matching ratios, so the answer is 3/4.

The value of the angle P and Q are equal which is equal to 36.86°.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
From Δ it is obtained that;
[tex]\rm cos P = \frac{B}H} \\\\ \rm cos P = \frac{16}{20} \\\\ P=cos^{-1}\frac{16}{20} \\\\ P= 36.86 ^0[/tex]

What is the component form of the vector whose tail is the point (-3,2) and whose head is the point (1, -6)?
Answer:
(4, -8)
Step-by-step explanation:
The components of a vector are found by subtracting the tail from the head.
__
Head - Tail = (1, -6) -(-3, 2) = (1 -(-3), -6 -2) = (4, -8)
⇒ The component form is (4, -8), or maybe 4i -8j.

What is the perimeter of the following shape? (use an approximate value) pie = 3.14
===========================================================
Explanation:
A full circle of radius r = 14 cm has a circumference of...
C = 2pi*r
C = 2*3.14*14
C = 87.92
This is the approximate distance around the circle, aka the perimeter.
Half of this is 87.92/2 = 43.96 which is the curved distance of this semicircle.
The straight line portion is 14+14 = 28 cm long.
The total perimeter of the semicircle shown is 43.96+28 = 71.96 cm

Nina and Jo both ran a 13 km race.
Nina took 2 hour 10 minutes to run the whole race.
Jo started the race 7 minutes later than Nina but caught up when they had both travelled 11 km.
If Nina and Jo both ran at constant speeds, what is Jo's speed to 2 dp?
We will see that Jo's speed, rounded to 2 digit places, is:
S = 6.42 km/h
How to get Jo's speed?
Remember that:
speed = distance/time.
Nina takes 2 hours and 10 minutes to finish the race, first, let's write the time in hours:
1 hour = 60 min.
Then:
10 min = (10/60) hours = 0.167 hours.
So we can write the time as:
2.167 hours.
And the distance is 13km, so her speed is:
S = 13km/2.167h = 6 km/h
The time that she takes to reach a distance of 11km (where she meets with Jo) is:
T = 11km/(6 km/h) = 1.83 hours.
Now, Jo starts 7 minutes after Nina, then the time in which he travels the 11 km is:
1.83 hours - 7 minutes.
Where:
7 min = (7min/60 min) hours = 0.117h
Then the time is:
T= 1.83h - 0.117h = 1.713 hours.
So he travels 11km in 1.713 hours, then his speed is:
S = 11km/ 1.713 hours = 6.42 km/h

What are supplementary angles?Supplementary angles are a pair of angles that always sum up to 180°. These angles can either;
adjacent non-adjacent. Adjacent supplementary anglesAdjacent supplementary are angles with a common vertex and arm.
Non-adjacent supplementary anglesNon- adjacent supplementary angles are angles without a common vertex or arm.
∠BAC and ∠CAD are adjacent supplementary angles because they have a common vertex, A, and a common arm AC.
They add up to 180°.
∠ BAC = 110° and ∠CAD = 70°

What is interval notation?It is defined as the representation of a set of values that satisfy a relation or a function. It can be represented as open brackets and close bracket the close the brackets means the value is at the close bracket also included, and open bracket means the value at the open bracket does not include.
We have:
Continuous set of all numbers between 5 and 6, including 5, but not including 6.
From the above statement we can represent the number in the interval notation:
The numbers are between 5 and 6.
