Answer:
7
Step-by-step explanation:
if the bases of the exponents are the same then we can add the powers. so 2^3 * 2^4 = 2^7 = 128.
Answer:
7
Step-by-step explanation:
2^3⋅2^4= 2^7
2^7=2^x
since it had the same base you wouldn't need to worry about it you can just focus on the exponent.
7=x
swap it over
x=7

-2(10 + x) = 4
Answer:
x = -12
Step-by-step explanation:
-2(10 + x) = 4
Divide each side by -2
-2(10 + x) / -2 = 4/-2
(10 + x) = -2
Subtract 10 from each side
10+x-10 = -2-10
x = -12
The solution to this equation is: x = -12
What is the first degree equation?First degree equation is an equality between members where we find at least one variable.
How to solve this equation?We have the equation:
[tex]\sf -2(10+x)=4[/tex]
First, we must apply the distributive property.
[tex]\sf -20-2x=4[/tex]
Now we move the independent term to the second degree.
[tex]\sf -2x=4+20[/tex]
We add similar terms.
[tex]\sf -2x=24[/tex]
We isolated the term "x".
[tex]\sf x=\dfrac{24}{-2}[/tex]
Finally, we carry out the division. Discovering, in this way, the solution.
[tex]\boxed{\boxed{\sf x=-12}}[/tex]

Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'c'...}}\\\\15.32 + c = 29.00\\-----------\\\rightarrow 15.32 - 15.32 = 29.00 - 15.32\\\\\rightarrow \boxed{13.68}[/tex]

She would have $13.68 dollars left. Her second item should be the soccer ball.

The area under the standard normal curve to the right of z = -0.51 is 0.6950. What is the area to the left of z = 0.51?
Answer:
0.305
Step-by-step explanation:
We are told that area under the standard normal curve to the right of z = -0.51 is 0.6950
Thus, to get the area to the left, we just subtract 0.6950 from 1.
Thus;
area to the left of z = 0.51 is;
P( z < 0.51) = 1 - 0.6950 = 0.305

Answer:
a) There are two possibilities for rigid transformation:
(i) 180° counterclockwise rotation around point B.
(ii) 180° clockwise rotation around point B.
b) Since transformation is rigid, it is suppose that every measure for sides and angles remains constant. In other word, sides and angles are conserved.
c) The corresponding angles and sides are presented below:

I have been having a lot of trouble with this assignment and I don't really understand some of the graph so if anyone can a little help would be great
Answer:
1. The graph represents the inequality y > 2x + 1
2. The y-intercept (where a line meets the y-axis) is at point (0,1). This line rises by 2 for every point it moves to the right (this is called the slope). A dotted line means that point on the line are not included in the solution set, thus you use the > symbol.
A new car that is a gas- and electric-powered hybrid has recently hit the market. The distance traveled on 1 gallon of fuel is normally distributed with a mean of 65 miles and a standard deviation of 7 miles. Find the probability of the following events: a. The car travels more than 69 miles per gallon. Proba
Answer:
0.28386
Step-by-step explanation:
Given that :
Mean, μ = 65 miles
Standard deviation, σ = 7 miles
Probability that car travels more than 69 miles per gallon :
Recall,
Z = (x - μ) / σ ; x = 69
Z = (69 - 65) / 7 = 0.5714
The probability :
P(Z > z) = P(Z > 0.5714) = 1 - P(Z < 0.5714)
P(Z > 0.5714) = 1 - P(Z < 0.5714) = 1 - 0.71614 = 0.28386
P(Z > 0.5714) = 0.28386
A helicopter hovers 500 m above a long straight road. There is a truck to the left and right of the helicopter. The angles of depression of the two trucks from the helicopter are 60° and 20°. How far apart are the two trucks?
Answer:
1045.01 rounded to the nearest hundredth
Step-by-step explanation:
First, we can draw this out. The angle of depression is the angle formed by the object at the top and the line formed by the object at the top and the object at the bottom.
If the truck on the left is truck A and the truck on the right is truck B, with the helicopter being the circle on top, there is one 60 degree angle of depression and one 20 degree one. If we make a point at the point in the road the helicopter is straight above, and we connect the points, we can form two right triangles, as shown. If we can calculate the lengths of sides x and y, we can add them up to find the length between the two trucks.
Starting with side x, we know one angle and the side length adjacent to that angle. We want to find the length opposite that angle. One formula that encompasses this is tan(θ) = opposite/adjacent. Therefore, tan(60) = x/500
tan(60) = x/500
multiply both sides by 500 to isolate the x
tan(60) * 500 = x
x = 866.0254
Similarly, with side y, we can say that tan(20) = y/500 and
tan(20) * 500 = y
y= 181.9851
The distance between the two trucks can be shown as x+y, so x+y= 1045.01 rounded to the nearest hundredth

What is a line segment?A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
The three points are W, X, and Y on the line.
From the diagram, the distance between the points W and X which is the line segment WX will be 2.
Similarly, from the diagram, the distance between the points W and Y which is the line segment WY will be 9.

Two angels of a triangle are the same size.The third angel is 3 times as large as the first. How large are the angels
Answer:
Let the two equal angles be x . Hence the third angle is 3x . But the sum of the interior angles of a triangle always adds up to 180∘ . ∴x=1805=36∘
Answer:
Angle 1 = 36°
Angle 2 = 36°
Angle 3 = 108°
Step-by-step explanation:
Sum of all angles in any triangle is 180°
angle 1 = angle 2 = X
angle 3 = 3×X
angle 1 + angle 2 + angle 3 = 180°
X + X + 3×X = 5×X = 180°
X = 180° / 5 = 36°
Angle 1 = 36°
Angle 2 = 36°
Angle 3 = 108°

Answer:
57.2
Step-by-step explanation:
This is a right triangle so we can use trig ratios.
We are asked to find a side when we know a angle adjacent to that side. And we are given a side opposite of that angle. We can use Tangent to find the side length.
[tex] \tan(40) = \frac{48}{x} [/tex]
Take the reciprocal of both sides.
[tex] \frac{1}{ \tan( 40) ) } = \frac{x}{ 48} [/tex]
Multiply both sides by 48.
[tex] x = \frac{1}{ \tan(40) } \times 48[/tex]
[tex]x = 57.2[/tex]
Identify a transformation of the function f(x) = x2 by observing the equation of the function g(x) = (x - 1)
Answer:
2nd option
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here g(x) = (x - 1)²
The base graph f(x) has been shifted right 1 unit

Answer:
DEF = 105
Step-by-step explanation:
The sum of the angles of a triangle is 180
28+47+DEF = 180
Combine like terms
DEF+75=180
Subtract 75 from each side
DEF +75-75 =180-75
DEF = 105
Answer: D
Step-by-step explanation: The answer is D because firstly we know that all right triangles add up to 180 degrees.
Using this knowledge we know 2 sides out of the 3. Therefore 47+28+x=180. Then we would add the first 2 numbers then minus 180 to get 105 as your last angle.
