Answer:
[tex]\lim_{x \to 0} =-\frac{1}{6}[/tex]
Step-by-step explanation:
The first step in evaluating a limit should be to plug in the number to see if you get a result
When you plug in 0 to all of the x's in the expression, you are left with the constants -1 on the top and 6 on the bottom of the fraction.
So there's no need to go any further, the limit as x approaches 0 is [tex]-\frac{1}{6}[/tex]
Answer:
-1/6
Step-by-step explanation:
To find the limit as x approaches 0 we can just plug in 0
for the numerator: 3*0+5*0-1 = -1
For the denominator: 4*0+2*0+6= 6
answer is just -1/6 or -.16666666666666666666667

Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
f(x) = - 0.6x² + 4.2x + 240 ← factor out - 0.6 from the first 2 terms
= - 0.6(x² - 7x) + 240
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 7x
f(x) = - 0.6(x² + 2(- 3.5)x + 12.25 - 12.25 ) + 240
= - 0.6 (x - 3.5)² + 7.35 + 240
= - 0.6(x - 3.5)² + 247.35
with vertex = (3.5, 247.35 )
The maximum value is the y- coordinate of the vertex
Then
f(x) = - 0.6(x - 3.5)² + 247.35 has a maximum value of 247.35

7.16.7.17
A. 7.142
B. 7.113.7.113
C. 7.113
D. 711
Answer:
C) (7.1)^13
Step-by-step explanation:
When you multiply numbers with the same bases but different exponents, the base stays the same, but the exponents get added:
a^x*a^y=a^(x+y)
(7.1)^6*(7.1)^7=(7.1)^(6+7)=(7.1)^13
Therefore, the correct answer is C) (7.1)^13
Answer:
C
Step-by-step explanation:
When multiplying numbers with exponents, you always add the exponents.
7.1^6+7
7.1^13
Hence, C

How many flowers, spaced every 3 in., are needed to surround a circular garden with a 125 -ft radius? Use 3.14 for (the pie symbol).
Answer:
785
Step-by-step explanation:
flowers needed to surround the garden = circumference of the garden / space
circumference of a circle = 2nr
n = 3.14
r = radius
The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability
1ft = 12 inches
125 x 3 = 375
2 x 3.14 x 375 = 2355
flowers needed = 2355 / 3 = 785

Actually Welcome to the concept of Geometric Progression.
So, we know that,
GP = a.r^(n-1)
here, a = 4 and r = -2
so we get as,
an = 4.(-2)^n-1
Option B.) is correct
Find the circumference of a circle with radius, r = 16.5m.
Give your answer in terms of pi.
Answer:
33π is the answer in terms of pi.
Step-by-step explanation:
Circumference of circle formula is C=πd.
Plug in the given values. We put 33 into d, because d represents diameter, and diameter is twice the radius(16.5), so we multiply 16.5 by 2. So far we have C=(π)(33).
C=(π)(33)=33π

Answer:

Step-by-step explanation:q
If you have a 30 degree reference angle, the side opposite (the side not part of the reference angle) is 1/2 the size of the hypotenuse.
Since the side opposite is 12, the hypotenuse is easily found.
1/2 = opposite / hypotenuse
1/2 = 12 / hypotenuse Cross multiply
hypotenuse = 2 * 12
hypotenuse = 24
Now use the Pythagorean Theorem to get the third side.
c = 24
a = 12
b = ?
a^2 + b^2 = c^2
12^2 + b^2 = 24^2
144 + b^2 = 576 Subtract 144 from both sides.
b^2 = 576 - 144
b^2 = 432
Now you have to factor 432 down to its primes
432 = 2 * 2 * 2 * 2 * 3 * 3 * 3
The rule is for every two 2s you take one outside the root sign and throw the other one away. If there are an odd number of factors, leave one of them under the root sign.
sqrt(b^2) = sqrt(432)
b = 4 * 3sqrt(sqrt(3))
b = 12 sqrt(3)
Answer
r = 12*sqrt(3)
t = 24
The answer is D

Answer:
x = 60° (Alternate angles)
Step-by-step explanation:
a) x = 60°
b) Reason: Alternate angles
Answer:x=60
Step-by-step explanation: all angles in a triangle add up to 180 degrees, x is the same as the angle next to it, therefore x=60 degrees

Use the tangent ratio to find the size of the angle marked x, correct to the nearest degree.
A faraway planet is populated by creatures called Jolos. All Jolos are either green or purple and either one-headed or two-headed. Balan, who lives on this planet, does a survey and finds that her colony of 852 contains 170 green, one-headed Jolos; 284 purple, two-headed Jolos; and 430 one-headed Jolos. One-headed Two-headed Total Green 170 Purple 284 Total 430 852 How many green Jolos are there in Balan's colony? O A. 138 B. 308 O C. 422 D. 260
Answer:
B. 308Step-by-step explanation:
Table is given belowFind the missing values.The one we are looking for is total of green = y.| 1 -H | 2-H | Total
Green | 170 | x | y
Purple | z | 284 | w
Total | 430 | v | 852
z = 430 - 170 = 260w = 260 + 284 = 544y = 852 - 544 = 308v = 852 - 430 = 422Correct choice is B
Is a acute triangle regular?
Answer:
An equilateral triangle may also be called a "regular" triangle. (A "regular" polygon has all equal sides and all equal angles.)An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral.

What is 2/5 divided by 4
the answer to the question is 0.1
Answer:
1/10 or 0.1
Step-by-step explanation:
You first rewrite the problem as 2/5÷4/1. Then you flip the second fraction for multiplication: 2/5*1/4. Now you multiply both numerators and denominators to get a final total of 2/20 which equals 1/10 or 0.1.
is 6:4 and 4:3 equivalent ratios?
Answer:
nooooo
Step-by-step explanation:
an equivalent ratio to 6:4 would be 3:2 and an equivalent ratio for 4:3 would be 8:6
hope this helps! :)
The ratios 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.
What are ratios and proportions?A proportion is a statement that two ratios are equal. It compares two ratios and states that they are equivalent.
No, the ratios of 6:4 and 4:3 are not similar. We must reduce each ratio to its simplest form in order to determine whether two ratios are equivalent (by dividing both the numerator and denominator by their greatest common factor).
For 6:4, the greatest common factor is 2, so we can simplify to:
6:4 = 3:2
For 4:3, there are no common factors other than 1, so it is already in its simplest form.
Since 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.

The Garys have a triangular pennant of area 420 in(squared)flying from the flagpole in their yard. The height of the triangle is 10 in less than 5 times the
base of the triangle. What are the dimensions of the pennant?
Answer:
The answer is given below:
Step-by-step explanation:
The computation of the dimension of the pennant is shown below:
As we know that
Area of the triangle = 1 ÷ 2 × base × height
where
x represents the base of the traingle
h represent the height that should be (5x - 10)
Now according to the above formula
420 = 1 ÷ 2 × x × (5x - 10)
840 = x(5x - 10)
840 = 5x^2 - 10x
5x^2 - 10x - 840 = 0
5(x^2 - 2x - 168) = 0
x^2 - 2x - 168 = 0
x^ - 14x + 12x - 168
x (x - 14) + 12(x - 14)
(x + 12) (x - 14)
So, here x = 14
Now height would be
= 5(14) - 10
= 60 inches
