Find x in the triangle below. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
Remark
x is opposite the 90 degree angle. It is the hypotenuse. 13 makes up the 57 degree angle. It is the side adjacent.The adjacent side and the hypotenuse define the cos(theta).Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
Cos(57) = 13 / x Multiply both sides by xx*cos(57) = 13 Divide by cos(theta)x = 13/cos(57)x = 13 / cos(57)cos(57) = 0.5446x = 13/ 0.5446x = 23.87
Solve the following equation. Then place the correct number in the box provided.
Answer:
x ≤ 6
Step-by-step explanation:
2x-1 ≤ x+5
Subtract x from each side
2x-x-1 ≤ x-x+5
x-1 ≤ 5
Add 1 to each side
x-1+1 ≤ 5+1
x ≤ 6

Answer:
a = 42 b = 21
Step-by-step explanation:
a is 42 since it ks vertically opposite 42
To solve for b
360 - (42×2)........to get the angle next to a
=276... Divde answer by 2. Bc there are two of the angles
276÷2 =138
138 + 2b =180
2b = 180 - 138
b = 42 ÷ 2
b = 21

The image below shows four soccer balls at different
locations on an uneven soccer field. Which ball has the
greatest amount of kinetic energy? Explain your answer.
Answer: letter d
Step-by-step explanation:
Answer:
Ball D. Among the four balls in this picture, ball D is the only one whose kinetic energy is greater than [tex]0[/tex].
Step-by-step explanation:
Consider an object of mass [tex]m[/tex]. If this object is moving at a speed of [tex]v[/tex], the kinetic energy of this object would be:
[tex]\displaystyle \frac{1}{2}\, m \cdot v^{2}[/tex].
The speed [tex]v[/tex] of ball A, B, and C are all [tex]0[/tex]. Hence, the kinetic energy of these three balls would be [tex]0\![/tex].
The speed of ball D is greater than [tex]0[/tex]: [tex]v = 2\; \rm m \cdot s^{-1}[/tex]. The kinetic energy of this ball would be:
[tex]\begin{aligned} {\rm KE} &= \frac{1}{2}\, m \cdot v^{2} \\ &= \frac{1}{2}\times \rm 0.43\; \rm kg \times \left(2\; \rm m \cdot s^{-1}\right)^{2}\\ &= 0.86\; \rm J\end{aligned}[/tex].
Hence, the kinetic energy of ball D is the greatest among the four balls in this picture.
Solve each inequality.
1. 5x + 2 <17
Answer:
x<3
Step-by-step explanation:
5x+2<17
Subtract 2 from both sides.
5x<17−2
Subtract 2 from 17 to get 15.
5x<15
Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.
x=15/5
Divide 15 by 5 to get 3.
x<3

Mr. Brown purchased tires for his car. The tires were $75 each, including tax, plus $10 for installation. Mr. Brown paid $160 for the tires and installation. Which equation can be used to find the number of tires, t, Mr. Brown purchased?
A. t = 160 + 75(10)
B. 75 + t(10) = 160
C. 75t + 10 = 160
D. 160t – 75 = 10
Answer:
C. 75t + 10 = 160
Step-by-step explanation:
Given that
The tire was $75 each
also there is a $10 for installation charges
For both he paid $160
Now based on the above equaton
The equation that applied to determine the number of tires i.e. t is
75t + 10 = 160
How can this model be used to determine 2.4−0.15 ? Enter your answers in the boxes. The model shows a total of 2 wholes and 4 tenths. After regrouping 1 tenth into 10 hundredths, there are 2 wholes, tenths, and hundredths. After crossing out 1 tenth and 5 hundredths, there are 2 wholes, tenths, and hundredths remaining. Therefore, the difference of 2.4 and 0.15 is .please help fast
Answer:
2.25
Step-by-step explanation:
2.4 - 0.15
Using place value :
2 = Unit (2 wholes)
4 = tenth place ( 4 tenths)
To subtract 0.15
0 wholes ; 1 tenth ; 5 hundredth
1 tenth can be split into 10 separate hundredths
Hence,
For 2.4
We have ;
2 wholes ; 3 tenths and 10 hundredths
Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth
(2 - 0) wholes = 2 whole
(3 - 1) tenth = 2 tenth
(10 - 5) hundredth = 5 hundredth
Hence, the difference between (2.4 and 0.15) is :
2 whole ; 2 tenth ; 5 hundredth
Which is equal to : 2.25

Car X travels 174 miles in 3 hours.
Answer:
The graph =
y = 58xStep-by-step explanation:
(a)
distance covered (y) = 174 miles
time taken (x) = 3 hours
Therefore the points = (3, 174) and (0, 0) = stationary position
Find the gradient (m)
m = 174-0 / 3-0
m = 58
Therefore the equation =
y = 58x(distance = 58 × time)
For the distance = 174 and time = 3 hours, the equation to find either distance or time = y = 58x
(b) the graph is constant, because the time and distance are also contant when the speed used is the same.

Which complex number's graph is shown?
Answer: Option D.
Step-by-step explanation:
When we want to graph a complex number in a coordinate axis, the real part of the complex number is represented by the x-axis, and the complex part is represented by the y-axis.
in this case, we can see that the coordinates of the point are:
(-2, 2)
Then the complex number is:
Z = -2 + 2*i
Now we need to see which one of the given options is equal to this.
Let's check the real part for every option, so we can discard some of them:
A) real part = -2*cos(135°) = 1.41 (we can discard this option)
B) real part = 2*cos(7*pi/4) = 1.41 (we can discard this option)
C) real part = √2*2*cos(225°) = -2
D) real part = √2*2*cos(3*pi/4) = -2
So options C or D are the correct one, now let's check the complex part for each one
C) complex part = √2*2*sin(225°) = -2 (we can discard this option)
D) complex part = √2*2*sin(3*pi/4) = 2
So the correct one is the D option.

How to get polynomials with zeroes?Let a, b, c, and d are the zeroes of the polynomial.
Then the polynomial is given as,
⇒ (x - a)(x - b)(x - c)(x - d)
The degree of the polynomial will be greater than or equal to the number of zeroes.
The zeroes of the function are -4, -2, and 4. Then the factor of the equation is given below.
x = - 4
x + 4 = 0
x = -2
x + 2 = 0
x = 4
x - 4 = 0
Then the polynomial is given below.
g(x) = (x + 4)(x + 2)(x - 4)
The polynomail that addresses the chart will be g(x) = (x + 4)(x + 2)(x - 4). Then the right choice is D.
