What would be the new exponent if you multiplied
10-2 x 105? Just write the number for the exponent.
Answer:
The number of the exponential is 3
Step-by-step explanation:
10^-2×10^5
According to the law when the base are equal you pick one then add the power when it is multiplication when it is division, you subtract the power
10^-2+5=10^3

If a+b=2 find the value of a3+b3+6ab
Answer:
Step-by-step explanation:
Factor the sum of cubes
a³ + b³ = (a+b)(a² - ab +b²)
= 2a² - 2ab + 2b²
a³ + b³ + 6ab = 2a² + 4ab + 2b²
= 2(a² + 2ab +b²)
= 2(a+b)²
= 8

don´t understanddd .....
Answer:
a = 32°
Step-by-step explanation:
My thought process was that the square below the 58° usually means that its a 90° angle, so I just did 90°-58°=32°
if your good at math pls help
1. Get a blank paper or sugar board or cardboard/ calendar to complete the given task.
2. Use your pencil and compass to scribe or draw three different size circles on the blank paper/ calendar/ cardboard/sugar board
3. At the back of each circle label them 1,2 and 3 respectively.
4. Next use your ruler to measure the radius of the circle which is from the center to the circumference of the circle.
Ensure to record your measurement.
5. Use your ruler and measure the diameter goes straight across the circle, through the center (radius).
Ensure to record the measurements for each circle.
6. Then you will repeat steps 4 and 5, while using a string along with your ruler to measurement the circumference for each of the circle. Ensure to record your measurements
7. After completing your measurement write a conclusion for what you observed about the measurements for the diameter, radius and circumference for the three circles.
Answer:
R: Radius.
D: Diameter.
1) R: 4cm
D: 8cm
2) R: 2;5cm
D: 5cm
3) R: 2cm
D: 4cm
Conclusion: Note that the radius and diameter measurements vary depending on the circumference measurement.
(To graph use the measurements of the diameter)
Good luck! :)
The axis of symmetry for the graph of the function f(x) = 3x^2 + bx + 4 is x = 3/2 . What is the value of b?
Answer:
b = -9
Step-by-step explanation:
Axis of symmetry of a parabola = -b / 2a.
Where y = ax² + bx + c.
Given f(x) = 3x^2 + bx + 4,
a = 3, and c = 4.
If the axis of symmetry is 3/2, than b can be found by substitution and algebra.
[ x = -b / 2a ] → [ 3 / 2 = -b / 2a ] →
[ 3 / 2 = -b / 2 (3) ] → [ 3 / 2 = -b / 6 ] →
[ 3 / 2 × 6 = -b / 6 × 6 ] → [ 18 / 2 = -b ] →
[ 9 = -b ] → [ -b = 9 ] → [ (-)(-b) = (-)(9) ] →
b = -9
easy question answer plssss
Answer:
Y = 1
Step-by-step explanation:
Proportional
Answer:
y=1
Step-by-step explanation:
Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.
Hope this helps

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle

a) 16.4 m, 101°b) 6.22 m, 51 m²Step-by-step explanation:
Find the measure of angle Q:
50° + (180° - 130°) = 100°a) Find PR using the law of cosines:
PR = √(8² + 13² - 28*13*cos 100°) = 16.4 m (rounded)Find ∠P using law of sines:
16.4/sin 100° = 13/ sin Pm∠P = arcsin (13 sin 100° / 16.4) = 51° (rounded)The bearing of R from P is:
50° + 51° = 101°b)
Find the measure of h, the distance from Q to PR:
h/ PQ = sin Ph = PQ sin Ph = 8 sin 51° = 6.22 mFind the area of ΔPQR:

I REALLY NEED HELP ASAP PLEASE EXPLAIN WILL GIVE BRAINLIEST!
Answer:
(I attached an image of the graphed lines)
Step-by-step explanation:
First, we need to graph the original function:
The given equation is written in y=mx+b form, in which m is the slope and b is the y-intercept, or where the line crosses through the y axis. This means the slope is [tex]\frac{2}{1}[/tex] and the y-intercept is -4.Next, we need to find the inverse of the function and graph that as well:
First, change f(x) in the given equation to y. These mean the same thing, it just makes it easier to work with.Swap the places of x and y. Then, the rest of the steps are essentially just isolating the variable y.Add 4 to both sides of the equation to cancel out the -4 (You will end up with -2y = x + 4)Divide both sides of the equation by -2 to isolate y (You will end up with y = (x/2) + 2)

!!!Please help will give the brainliest, and please do not put in a silly answer because you want some points or I will report you!!! What are the properties for each of these shapes and please be specific for each, a kite, trapezoid, square, rectangle, parallelogram, rhombus?
Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.

Answer: positive, linear association
Step-by-step explanation: that is the answer, because the dots are rising up in a slope
Answer:
The answer is simple: Positive, linear association. Why is that? It is moving from left to right, increasing as it goes. That is a sign of a positive slope. And, this has a linear association because the points are jumbled together in a clear direction, so we know that we can place a line of best fit.

A cattle rancher needs to construct a new silo in which to store cattle feed. The silo will cost $2000. The rancher pays 15% as a down payment and finances the balance for 60 months at an APR of 7.50% . Determine the rancher's total finance charge and monthly payment.
a) Total finance charge = $368.22; Monthly payment =$34.47
Answer:
Monthly payment = $34.06
Finance charge = $343.87
Step-by-step explanation:
Given that:
Cost of silo = $2000
Down payment = 15% = (0.15) * 2000 = $300
Loan amount = $2000 - $300 = $1700
Period = 60 months = 5 years
APR = 7.5%
Using then monthly payment calculator, with the satiated parameters inputted :
The monthly payment is $34.06
The total amount paid over 60 months = $2,043.87
Therefore, finance charge = (total amount paid - loan amount)
$2043.87 - $1700
= $343.87
