Answer:
Triangle M'L'Q' was dilated by a scale factor of 3
Step-by-step explanation:
Well, 4 times 3 is 12 and 7 times 3 is 21, so that means the new triangle was dilated by a scale factor of 3.
While parasailing. Ryan spots a dolphin on the water below. If Ryan is 228 feet above the
water and the angle of depression to the dolphin is 15, what is the horizontal distance
between Ryan and the dolphin?
Answer:
850.9 feet
Step-by-step explanation:
The horizontal distance between Ryan and the dolphin is 850.907 feet.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.
Using trigonometry
tan 15 = 228/ x
x= 228/ tan 15
x= 228 / 0.26794919243
x = 850.907 feet

Hello there!
Prime numbers have 2 factors and composite numbers have 3 or more factors.
17 is prime because it has only 2 factors: 1 and itself.
54 is composite because it has more than 3 factors.
77 is composite because it has more than 3 factors.
23 is prime because it has only 2 factors.

What is the area, in square meters, of the figure below?
Answer:
[tex]0.55[/tex] square meters
Step-by-step explanation:
The area of a triangle can be calculated by multiplying its height and base, then dividing the result by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] is the base and [tex]h[/tex] is the height. In this case, [tex]b=2.2[/tex] and [tex]h=0.5[/tex]. Therefore, the area of the triangle is:
[tex]\frac{bh}{2}\\= \frac{2.2*0.5}{2}\\=\frac{1.1}{2} \\= 0.55[/tex]
Hope this helps!
By observing the diagram, we have :
Base of triangle, b = 2.2 mHeight of triangle, h = 0.5 mNow, we know that :
[tex] \large \underline{\boxed{\tt{Area_{(triangle)} = \dfrac{1}{2} \times base \times height}}}[/tex]
So, by substituting values, Area of given triangle will be :
[tex] \sf : \implies Area = \dfrac{1}{2} \times 2.2\: m \times 0.5\: m[/tex]
[tex] \sf : \implies Area = \dfrac{1}{\cancel{2}} \times \dfrac{\cancel{22}}{10} \: m \times \dfrac{5}{10} \: m[/tex]
[tex] \sf : \implies Area = 1 \times \dfrac{11}{10} \: m \times \dfrac{5}{10}\: m[/tex]
[tex] \sf : \implies Area = \dfrac{55}{100} \: m^{2}[/tex]
[tex] \sf : \implies Area = 0.55 \: m^{2}[/tex]
Hence, Area of given triangle is 0.55 m².

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
What domain makes sense for the function in this context?
A. all positive numbers
B. 0 ≤ t ≤ 5
C. all real numbers
D. 0 ≤ t ≤ 100
Answer:
B. 0 ≤ t ≤ 5Step-by-step explanation:
The function is g(t) = -16t² + vt + h
At h = 0 and v = 80 we get the function:
g(t) = -16t² + 80tWe know g(t) can't be negative, then:
-16t² + 80t ≥0t² - 5t ≤ 0t(t - 5) ≤ 5t ≥0 and t ≤ 5, or0 ≤ t ≤ 5Correct option is B

Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3

Please help 25p- it’s urgent
Answer:
p = 20, q = 20, r = 30
Step-by-step explanation:
The triangle to the left of OA is isosceles ( 2 equal radii ), then the base angles are congruent, so
p = 20
The 3 angles in this triangle sum to 180°, then the angle at O is
180 - (20 + 20) = 180 - 40 = 140°
AB is a straight line so angle in triangle containing q is 180 - 140 = 40
The triangle containing q is also isosceles ( 2 equal radii ) then base angles are congruent, then
q = [tex]\frac{180-140}{2}[/tex] = [tex]\frac{40}{2}[/tex] = 20
The triangle to the right of OA is also isosceles ( 2 equal radii ) then the base angles are congruent, so
r = 30
Then p = 20, q = 20, r = 30
