Answer:
Step-by-step explanation:
To have anything to a power is just multiplying the number as many times as it says to. ex. 2^3 is two times itself 3 times. 2 x 2 x 2= 8
In your case, you need to multiply -4 x -4 because the exponents tell you how many of the number you multiply.
-4 x -4 = 16
Hope this helps :)
What is this in standard form
Answer:
Standard form is a way of writing down very large or very small numbers easily. For example, 4000 can be written as 4 × 10³.
You are running a fuel economy study. One of the cars you find is blue. It can travel 38 1/2 miles on 1 1/4 of gasoline. Another car is red. It can travel 21 3/5 on 4/5 of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon of gasoline?
Answer:
Blue car: 30.8 miles per galon
Red car: 27 miles per galon
Blue car can travel longer distances on one galon!
Step-by-step explanation:
Blue car:
38 1/2=77/2=38.5 miles
1 1/4=5/4=1.25 gasoline
38.5/1.25=30.8miles per galon
Red car:
21 3/5=108/5=21.6 miles
4/5=0.8 gasoline
21.6/0.8=27 miles per galon

What is an
equation of the line that passes through the points (-6,5) and (6, 7)?
Answer:
[tex]y = \frac{1}{6} x + 6[/tex]
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
Use the gradient formula below to find the value of m:
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
*(x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
[tex]m = \frac{7 - 5}{6 - ( - 6)} \\ m = \frac{2}{12} \\ m = \frac{1}{6} [/tex]
Substitute the value of m into the equation:
y= ⅙x +c
To find the value of c, substitute a pair of coordinates.
When x= 6, y= 7,
[tex]7 = \frac{1}{6} (6) + c \\ 7 = 1 + c \\ c = 7 - 1 \\ c = 6[/tex]
Thus, the equation of the line is y= ⅙x +6.

y=-x-4
y=x
solve system of equations algebraically
Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2

A park is showing a movie on the lawn. The base of the screen is 6 feet off the ground and the screen is 22 feet high (see figure).
Answer:
A. 61.82°;
15.64°
B. 33.37°
Step-by-step explanation:
A.
✍️Angle of elevation from 15 ft:
A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 15 ft
Thus, we would have:
[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{15} [/tex]
[tex] tan(\theta) = 1.8667 [/tex]
[tex] \theta = tan^{-1}(1.8667) [/tex]
[tex] \theta = 61.82 [/tex] (2 d.p)
✍️Angle of elevation from 100 ft:
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 100 ft
Thus, we would have:
[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{100} [/tex]
[tex] tan(\theta) = 0.28 [/tex]
[tex] \theta = tan^{-1}(0.28) [/tex]
[tex] \theta = 15.64 [/tex] (2 d.p)
B.
✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:
Adjacent length = your distance from the screen = x
Opposite length = 22 + 6 = 28 ft
Angle of elevation = 40°
Tge trigonometric ratios formula to use would be:
[tex] tan(\theta) = \frac{opp}{adjacent} [/tex]
Plug in the values
[tex] tan(40) = \frac{28}{x} [/tex]
Multiply both sides by x
[tex] x*tan(40) = 28 [/tex]
Divide both sides by tan(40)
[tex] x = \frac{28}{tan(40)} [/tex]
[tex] x = 33.37 [/tex] (2 d.p)

Use the explicit formulas below to find a 1 ,ab nd a 10 for each formula . Show your a . A n =n^ 3 +4 b . A n =-5n+3
Answer:
Step-by-step explanation:
The question is not properly written.
Use the explicit formulas below to find a1 ,and a10 for each formula . Show your work a . An =n^3 +4 b . An =-5n+3
a) If An = n^3 + 4
To get a1, we will substitute n = 1 into the equation as shown;
a1 = 1^3 + 4
a1 = 1+4
a1 = 5
If An = -5n+3
A1 = -5(1)+3
A1 = -5+3
A1 = -2
b) If An = n^3 + 4
To get a10, we will substitute n = 10 into the equation as shown;
a10 = 10^3 + 4
a10 = 1000+4
a10 = 1004
If An = -5n+3
A10 = -5(10)+3
A10 = -50+3
A10 = -47

Answer:
Not a function
Step-by-step explanation:
This is not a function because every x value has more than one y value. Think about it this way. If you have a person and you are telling them to go to three different places at once, they can't. That means this isn't a function. Hope this helps!
Answer: That is not a function

Joseph’s lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip without tax? *
Answer:
17% of 13 is 2.21
13 + 2.21 = 15.21
Step-by-step explanation:
Joseph's lunch costs = $13 without taxes
He leaves tip for the waiter = 17% of cost of the lunch
= 17% of $13
= 13 ×
= ( 13 × 0.17)
= $2.21
Total cost of lunch + tip = 13 + 2.21
= $15.21

c. Angle KHE is congruent to angle KFG.
d.Angle GHK is congruent to angle KHE.
e. Segment EH is congruent to segment FG.
f. Segment GH is congruent to segment EF.
Answer: C, E, F
Step-by-step explanation: dude tbh idek but ik that it’s the right answer
The true statements are:
Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.Given:
Triangle HEF is the image of triangle FGH after a 180-degree rotation about point KAnd Six statementsTo find:
The true statements out of given sic statements.
Solution:
ΔHEF is the image of ΔFGH after a 180°rotation about point K.
This simply implies that ΔFGH is congruent to ΔHEF. As no dilation is done while rotation of the ΔFGH.
In congruent ΔFGH and ΔHEF
HF = HF (common)GH = EFFG = EH∠FGH=∠HEF∠GFH=∠EHFCan also be written as:
⇒ ∠KFG=∠KHE
∠GHF=∠EFHCan also be written as:
⇒ ∠GHK=∠EFK
So, from the given statements the true statements are:
Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.Learn more about the congruency of triangles here:

unitary method examples.
Answer:
For example, if a car runs 44 km on 2 litres of petrol then we can use the unitary method to find out the kilometres it will cover on 1 litre of petrol. In other words, the method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.
