Answer:
65°
Step-by-step explanation:
Complementary angles add up to 90°. This means the measure of the other angle can be represented as
90° - 25°
or
65°

What is the area of the right triangle shown below?
Answer:
1.5
Step-by-step explanation:
base x height x 0.5
Pythagorean theorem: c^2 - a^2 = b^2
b = square root of (2.5)^2 - (1.5)^2
= 2
b = height
area = 0.5 x 1.5 x 2 = 1.5
Answer:
1.5
Step-by-step explanation:
Use the Pythagorean Theorem. A^2 + b^2 = c^2
A and b being the sides and C being the hypotenuse.
2.5^2 - 1.5^2 = 4
Square root of 4 is 2.
Then you use the area of a triangle formula. 1/2 * base * height = Area of a triangle.
1.5 * 2 * 0.5 = 1.5

A circle centered at the origin has a radius of 13. The terminal side of an angle x, intercepts the circle in quadrant IV at point C. The x coordinate of point C is 12. What is the value of sin x
Answer:
[tex]sin x=-\frac{5}{13}[/tex]
Step-by-step explanation:
From the question we are told that:
Radius [tex]r=13[/tex]
Co-ordinate of x axis at C [tex]x'=12[/tex]
Let
x' represent the x axis
y' represent the y axis
Since the intercept across the radius has values on the x' and y' axis
Therefore
Generally the Trigonometric equation for cos x is mathematically given by
[tex]cos x=\frac{x'_c}{r}[/tex]
[tex]cos x=\frac{12}{13}[/tex]
Generally the Trigonometric equation for sin x is mathematically given by
[tex]sin x=\sqrt{1-cos^2x}[/tex]
[tex]sin x=\sqrt{1-(\frac{12}{13})^2}[/tex]
[tex]sin x=\frac{5}{13}[/tex]
Since x is in the IV quadrant sin x is negative
[tex]sin x=-\frac{5}{13}[/tex]

tan(56)=10/x
tan(56)/10=1/x
10/tan(56)=x
x=6.745 which rounds to 6.7
2x-56=34 solve for x
Answer:
x = 45
Step-by-step explanation:
2x - 56 = 34
2x = 34 + 56
2x = 90
x = 45
Answer:
x = 45
Step-by-step explanation:
2x-56=34 add 56 to both sides
2x = 90 divide both sides by 2
x = 45
A coin is tossed 10 times. 4 of the 10 tosses result in heads. What is the THEORETICAL probability of landing on heads
Answer:
1 /2
Step-by-step explanation:
The theoretical probability is the possibility of an event occurring based on reasoning and not on the outcome of a trial or experiment. Hence, for the question above, the outcome of the tosses or trials would have no effect on the theoretical probability that a coin lands oon head or tail.
Theoretical probability of an event =
Favorable outcome / Total possible outcomes
Favorable outcomes = number of heads in a coin = 1
Total possible outcomes = number of faces on a coin = 2 (head and tail)
Therefore,
Theoretical probability of landing on head = 1 /2
The horizontal cross section shown is a parallel to the base of the pyramid is the shortest side of the cross-section measures 1.2 cm what is the measure of the cross
Answer:
The longest side of the cross-section is: [tex]2.4cm[/tex]
Step-by-step explanation:
Given
See attachment for pyramid
Required
The longest side of the cross-section
The base of the pyramid is a rectangle with the following dimension (in terms of length)
[tex]Long = 6cm[/tex]
[tex]Short = 3cm[/tex]
For the cross-section, we have:
[tex]Long = x[/tex]
[tex]Short =1.2cm[/tex]
Since both are parallel, then the following relationship exist between both
[tex]Ratio = Long : Short[/tex]
So, we have:
[tex]6cm : 3cm = x: 1.2cm[/tex]
Express as fraction
[tex]\frac{6cm }{ 3cm }= \frac{x}{1.2cm}[/tex]
[tex]2= \frac{x}{1.2cm}[/tex]
Make x the subject
[tex]x = 2 * 1.2cm[/tex]
[tex]x = 2.4cm[/tex]

Answer:
The probability of getting a 1, 2, 3 on three rolls respectively is [tex]\frac{1}{216}[/tex].
Step-by-step explanation:
Since you are rolling three dies, and each die has six sides, that means there are a total of 216 possible outcomes. Out of the 216 different outcomes, only 1 of them meet the requirement of rolling a '1' on the first die, a '2' on the second die, and a '3' on the third die, so the fraction to represent the situation would be [tex]\frac{1}{216}[/tex].

What is the median of the data?
Answer: Median: 10
Step-by-step explanation:
Answer: 10
Step-by-step explanation: First you place the numbers in order from least to greatest (5,5,7,9,11,12,16,23) then you take away one from each side at a time so 5,23 then 5,16 etc. you end up with 9 and 11 left so you find the middle of 9 and 11 which is 10.

what is the area of the figure?
Answer:
[tex] 88 \: {in}^{2} [/tex]
Step-by-step explanation:
Area of the figure = Area of rectangle with dimensions 16 in and 4 in + Area of two right triangles with base (7 - 4 = 3) 3 in and height 8 in
[tex] = 16 \times 4 + 2 \times \frac{1}{2} \times 3 \times 8 \\ \\ = 64 + 24 \\ \\ = 88 \: {in}^{2} [/tex]

What is the meaning of f '' (4) = -4?
Hi there!
f''(4) = -4 means that at x = 4, the second derivative is equal to -4. This is equivalent to the instantaneous rate of change of the graph of f'(x) at x = 4 as well.
Answer:
Step-by-step explanation:
if the second derivative is -4 means that the function is concave down and that at point 4 the function has a maximum
Find the dividend if quotient is x–3, remainder is 7x–9 and divisor is x^2-2
Answer:
[tex]\implies Dividend = x^3-3x^2+4x-3[/tex]
Step-by-step explanation:
Given :-
Quotient is x–3, remainder is 7x–9 and divisor is x^2-2 .And we need to find out the Dividend. We know that ,
[tex]\implies Dividend = Quotient\times Divisor + Remainder [/tex]
Substituting the respective values :-
[tex]\implies Dividend = (x-3)(x^2-2)+7x-9 \\\\\implies Dividend = x^3-2x-3x^2+6+7x-9 \\\\\implies Dividend = x^3-3x^2+4x-3[/tex]
