A leg of a right triangle is 16 inches. The hypotenuse is 34 inches. How long is the other leg?
Answer:
hypotenuse ( c²) = a² + b²
- assume you're given the side a, find b:
b² = c² - a²
b² = (34)² - (16) ²
b² = 1156 - 256
b² = 900
b = √ 900
b = 30
therefore, the other leg is 30 inches.
Answer :
30 inches
Step-by-step explanation:
To determine one of the side lengths of a right triangle we can use the Pythagorean formula :
a² + b² = c²
→ Solutionb = 16 in
c = 34 in
a² + b² = c²
a² + 16² = 34²
a² + 256 = 1.156
a² = 1.156 - 256
a² = 900
a = √900
a = 30 in

What is the axis of symmetry?
What's the coordinate of the vertex?
Answer:
axis of symmetry: x = 0.3vertex: (0.3, 2.45)Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is x=-b/(2a). For your quadratic with a=-5, b=3, the axis of symmetry is ...
x = -(3)/(2(-5))
x = 3/10 . . . . axis of symmetry
__
The coordinates of the vertex are found by evaluating the function at x=3/10.
f(3/10) = (-5(3/10) +3)(3/10) +2 = 1.5(3/10) +2 = 0.45 +2 = 2.45
The vertex is (0.3, 2.45).
A post office sells stamps with 10 different images on them: flowers, trees, insects, birds, landscapes, constellations, frogs, mountains, fish, and bears. The post office has an equal amount of each stamp. One stamp is selected at random. Determine the theoretical probability of selecting a tree or frog stamp. Express your answer as a fraction in simplest form.
Using the it's concept, it is found that the theoretical probability of selecting a tree or frog stamp is of 0.2 = 20%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.

Find the equation of the line parallel to y = 3x - 2 that passes through
the point (4.8) in slope-intercept form.
Answer:
y = 3x - 4
Step-by-step explanation:
a line parallel to another will have the same slope, just a different y-intercept or b-value. Using this, we suggest the equation of the question [tex]y = 3x + b\\[/tex], as we can solve for b. The point (4,8) was given, which means that an input of 4 as x returns 8 as y. Thus, [tex]8 = 3(4) + b[/tex]. Solving this gains b = -4

What is the measure of the missing angle?
A cannot be determined
B 59 degrees
C 10 degrees
D 121 degrees
Answer:
The angle is 59 degrees.
Step-by-step explanation:
A triangle's angles, in total, must equal 180 degrees.
71 + 50 + (6x-1) = 180
71 +50 = 121
121 + (6x-1) = 180
6x - 1 = 59
A rectangular corral is enclosed using 120m of fencing. The corral uses the side of a barn as one of its sides, so fencing is required on three sides of the rectangular region. What dimensions would be maximize the area enclosed by the fence?
A. 30m x 60m
B. 10m x 100m
C. 7m x 106m
D. 20m x 80m
Answer: 30m x 60m
The dimensions that would maximize the area enclosed by the fence is 30m × 60m.
Area of a rectangle:area = lwwhere
l = length
w = width
Perimeter of a rectangle:perimeter = 2l + 2wTherefore,
The corral uses the side of a barn as one of its sides, so the fencing is required on three sides of the rectangular region. Therefore,
perimeter = L + 2w
L + 2w = 120
L = 120 - 2w
area = Lw
area = (120 - 2w)w
area = 120w - 2w²
area = -2w² + 120w
We have a quadratic equation and it is parabolic. The leading coefficient is negative. Therefore, the parabola opens downward and the vertex is the maximum point.
The area is maximized at the vertex. Therefore,
To find the vertex, we need to have our quadratic equation in general form,
ax² + bx + c = 0
so a = -2, b = 120
w = -b / 2a
w = - 120 / 2 × -2
w = -120 / -4
w = 30
Therefore,
area = -2(30)² + 120(30)
area = 1800m²
Therefore, the maximum area we can enclose is 1800 m², the width is 30m, then the length will be 60 m because 60 × 30 = 1800 m².

The value of sin2 Θ is in the 4th quadrant is -24/25
Explanation:
Given the expression of cosΘ= 3/5 with Θ in quadrant 4;
According to SOH, CAH TOA;
cosΘ= adjacent/hypotenuse
Get the opposite
5² = opp² + 3²
opp² = 25 - 9
opp² = 16
opp = 4
SinΘ = opp/hyp
SinΘ = 4/5
Sin2Θ = 2sinΘ cosΘ
Sin2Θ = 2(-4/5)(3/5)
Sin2Θ = -24/25
Hence the value of sin2Θ is in the 4th quadrant is -24/25

Find the measure of each acute angle of right triangle ABC with m
Answer:
The value of the angles are 38° and 52° respectively
Let the acute angles be represented by a and b.
Based in the information given,
a = 2(b - 12)
a = 2b - 24.
Note that the angle in an acute angle equals to 90°.
Therefore,
a = 90 - b.
a = 2b - 24
Equate the equations together
90 - b = 2b - 24
2b + b = 90 + 24
3b = 114
b = 114/3
b = 38
Therefore, a will be:
= 90° - 38° = 52°
The value of the angles are 38° and 52° respectively.

Find an equation of the tangent line to y = 2e^x sec(x) at x = pi/4
Answer:
y = 6.20 + 12.4(x - pi/4)
Step-by-step explanation:
dy/dx = 2e^x secx + 2e^x secx * tanx= 2e^x secx (1 + tanx)
At x = pi/4, use sec(pi/4) = [tex]\sqrt{2}[/tex]. tan(pi/4) =1
so dy/dx = 2e^(pi/4) * [tex]\sqrt{2}[/tex] * (1 + 1) = [tex]4 \sqrt{2} e^{\pi/4}[/tex] ≈ 12.4 (This is the slope of the tangent line)
When x = pi/4, y = 2e^(pi/4) * [tex]\sqrt{2}[/tex] = [tex]2 \sqrt{2} e^{\pi/4}[/tex]= 6.20
Then the equation of the tangent line is
y = 6.20 + 12.4(x - pi/4)

Jina got a prepaid debit card with $15 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of
ribbon was 21 cents per yard. If after that purchase there was $12.69 left on the card, how many yards of ribbon did Jina buy?
Answer:
the first answer
Step-by-step explanation:
I looked at it
Subtraction is a mathematical operation that reflects the removal of things from a collection. The yards of ribbon that were bought by Jina is 11 yard.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given that Prepaid credit card amount = $15
Also, She bought some bulk ribbon at a craft store and the price of ribbon was 21 cents per yard.
If after that purchase there was $12.69 left on the card.
Now, we can write the following details,
The amount on the credit card = $15
The amount spend on buying the ribbon = $0.21 cents per yard
The amount left on the credit card = $12.69
Further, we can write,
The amount that was used to buy the ribbon
= $15 - $12.69
= $2.31
Now, the length of the ribbon bought by Jina is,
Length of ribbon = $2.31 / $0.21 per yard = 11 yards
Hence, the yards of ribbon that were bought by Jina is 11 yard.
