Answer:
47
Step-by-step explanation:
Formula for finding nth term of an arithemetic sequence is:
tn = t1 + (n-1) d
Where t1 is the first term, n is the specific term, and d is the common difference.
Plug numbers into the formula and solve:
t8 = 5 + (8-1)6
t8 = 47
Robert says that he can draw an obtuse equilateral triangle. Jonas says that is not possible. Who is correct and why?
A.
Robert is correct as long as the other two angles are acute and all of the sides are the same length.
B.
Jonas is correct because an equilateral triangle has 3 acute angles and all sides the same length.
C.
Robert is correct because all equilateral triangles have 1 obtuse angle and all sides the same length.
D.
Jonas is correct because equilateral triangles have one right angle and two sides the same length.
Answer:
The correct answer is B. Jonas is correct because an equilateral triangle has 3 acute angles and all sides the same lenght

can you please help? f(x)=x^2 what is g(x)?
Answer:
D
Step-by-step explanation:
g(x) will be -x^2-3. The minus in front of the x makes the graph flip upside down, and the "-3" indicates its position on the y-axis. Hope this helps!!
Answer: Choice D. g(x) = -x^2-3
==============================================
Explanation:
Start with the curve y = x^2.
Reflect it over the horizontal x axis to get y = -x^2
Then shift everything down 3 units to arrive at g(x) = -x^2-3

True or false question. In Standard form, the number 3.5 *10^4 is 3,500.
Answer: False
Step-by-step explanation:
10^4=10000. 10000*3,5=35000.
Answer:
No, you missed a zero.
Step-by-step explanation:
In the given case, as we have the number as
3.5 × 10^4, we need to move decimal digit to the right by three points. For this, let us write 3.5 as 3.50000 and moving decimal point four points to right means
35000.0
Hence in standard notation
3.5 × 10^4=35,000
Jason has 208 baseball cards. This is 52 less than the number of cards that Robert has.
Which equation below best represents this scenario?
A) R+ 208= 52
B) R- 52 = 208
C) 52 - R = 208
D) 208 - 52 = R
Answer:
B) R - 52 = 208
Step-by-step explanation:
Robert has 52 more cards than Jason, who has 208, so Robert has 208 + 52 cards. This can be turned into:
R = 208 + 52
then subtract 52 from both sides:
R - 52 = 208 + 52 - 52
R - 52 = 208
and that's the answer
It typically takes Mr. Dunn 20 minutes to get to school, but it took him 40% longer today. How long did it take Mr. Dunn to get to school today?
EXPLAIN THE ANSWER
Answer:
28 minutes
Step-by-step explanation:
40 percent is 0.4 and 100 percent is 1. Since you have the full 100% of 20 plus the increase of 40% you have to multiply by 20 by 1.4
1.4*20 = 28

Given the functions f(x) = 2x + 1 and g(x) = 5x +4, find m(x) = f(x) - g(x)?
А. m(x) = 3x + 3
B. m(x) = -3x + 5
C. m(x) = -3x - 3
D. m(x) = 7x + 5
Answer:
m(x) =-3x -3
Step-by-step explanation:
f(x) = 2x + 1
g(x) = 5x +4
f(x) -g(x) = 2x + 1 -( 5x +4)
Distribute the minus sign
f(x) -g(x) = 2x + 1 -5x -4
Combine like terms
= 2x-5x +1 -4
= -3x -3

f the measure of angle BCD is 67.4°, the measure of angle ABC is °. If the length of base AB is 80 feet, the length of DC is feet.
Answer:
[tex]\angle ABC = 112.6^o[/tex]
[tex]DE =105[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
[tex]\angle ABC[/tex] and side length DC
Calculating [tex]\angle ABC[/tex]
First, calculate [tex]\angle EBC[/tex]
[tex]\angle EBC + \angle BCE + 90 = 180[/tex] --- angles in a triang;e
[tex]\angle BCE =\angle BCD = 67.4[/tex]
So:
[tex]\angle EBC + 67.4+ 90 = 180[/tex]
[tex]\angle EBC + 157.4 = 180[/tex]
Collect like terms
[tex]\angle EBC = 180-157.4[/tex]
[tex]\angle EBC = 22.6[/tex]
So:
[tex]\angle ABC = \angle EBC +90[/tex]
[tex]\angle ABC = 22.6 +90[/tex]
[tex]\angle ABC = 112.6^o[/tex]
Calculating DC
First, calculate EC using Pythagoras theorem.
[tex]BC^2 = BE^2 + EC^2[/tex]
[tex]65^2 = 60^2 + EC^2[/tex]
[tex]4225 = 3600 + EC^2[/tex]
Collect like terms
[tex]EC^2 =4225 - 3600[/tex]
[tex]EC^2 =625[/tex]
Take square roots
[tex]EC = 25[/tex]
Length DC is:
[tex]DC = DE + EC[/tex]
Where
[tex]DE = AB =80[/tex]
So:
[tex]DE =80+25[/tex]
[tex]DE =105[/tex]
Answer:
ABC= 112.6
DC= 105

Because the variable m does not appear in Ax + By = C, equations in this form make it impossible to determine the line's slope m. If the statement does not make sense, then how can you find m and what would it be? Show your work.
Answer:
Step-by-step explanation:
The statetement does not make sense because we can rewrite the equation of the line in the slope intercept form
1) add -Ax at both members
Ax + By - Ax = -Ax + C
By = -Ax + C
2) divide both members by B (assuming that its value is not 0)
y = (-A/B) x + C/B
the slope of the line is the therm that multiply x, so
m = -A/B

Answer:
KQ = 11.5 units
Step-by-step explanation:
In triangle ABC,
K is the point of intersection of medians AP and BQ.
Therefore, point K will be the centroid of the triangle.
Property of the centroid of a triangle,
" Centroid of a triangle divides the median in the ratio of 2 : 1"
Ratio of BK and KQ = 2 : 1
[tex]\frac{BK}{KQ}=\frac{2}{1}[/tex]
[tex]\frac{23}{KQ}= \frac{2}{1}[/tex]
[tex]KQ = \frac{23}{2}[/tex]
KQ = 11.5
Therefore, length of segment KQ = 11.5 units
Raju's father is 26 years younger than raju's grandfather and 29 years older than raju. The sum of the ages of all the three is 135 years. Also raju's grandmother is 4 times raju's age and his sister is 7 times younger than him
Answer:
Raju = 17 years
Raju's father age = 46 years
Raju's grandfather age = 72 years
Raju's grandmother = 68 years
His sister = 10 years old
Step-by-step explanation:
Raju’s father is 26 years younger than Raju’s grandfather and 29 years older than Raju. The sum of the ages of all the three is 135 years. Also, Raju's Grandmother is four times of Raju’s age and his sister is 7 years younger than him.
Let
Raju's age = x
Raju's father age = x + 29
Raju's grandfather age = (x + 29) + 26
Total ages = 135
(x) + (x + 29) + (x + 29) + 26 = 135
x + x + 29 + x + 29 + 26 = 135
3x + 84 = 135
3x = 135 - 84
3x = 51
x = 51 /3
x = 17
Raju's age = x = 17 years
Raju's grandmother = 4 times raju's age
= 4 × 17 years
= 68 years
his sister = 7 years younger than him.
= 17 - 7
= 10 years old
Raju's father age = x + 29
= 17 + 29
= 46 years
Raju's grandfather age = (x + 29) + 26
= 46 + 26
= 72 years

Determine the equation of the circle graphed below.
Answer:
[tex](x-4)^2+(y+3)^2=20[/tex]
Step-by-step explanation:
The equation of a circle with center [tex](h,k)[/tex] and radius [tex]r[/tex] is given by [tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
Center at [tex](4,-3)[/tex]To find the radius, we can use the distance formula. For points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex], the distance between them is [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].
Let
[tex](x_1,y_1)\implies (-4, -3),\\(x_2,y_2)\implies (8,-1)[/tex]
[tex]r=\sqrt{(8-4)^2+(-1-(-3))^2},\\r=\sqrt{4^2+2^2},\\r=\sqrt{20}=2\sqrt{5}[/tex]
Thus, the equation of this circle is
[tex](x-4)^2+(y-(-3))^2=\sqrt{20}^2,\\\boxed{(x-4)^2+(y+3)^2=20}[/tex]

2(5x + 3) + 2 = 10x + 6
A-one solution
B-infinitely many solutions
c-no solution
Answer:
C
Step-by-step explanation:
Given
2(5x + 3) + 2 = 10x + 6 ← distribute and simplify left side
10x + 6 + 2 = 10x + 6
10x + 8 = 10x + 6 ( subtract 6 from both sides )
10x + 2 = 10x ( subtract 10x from both sides )
2 = 0 ← not possible
This indicates the equation has no solution
Answer:
no solutions
Step-by-step explanation:
2(5x + 3) + 2 = 10x + 6
* solve for x *
step 1 distribute the 2 to 5x and 3
2 * 5x = 10x
2*3=6
we now have 10x + 6 + 2 = 10x + 6
step 2 combine like terms
6 + 2 = 8
we now have 10x + 8 = 10x + 6
step 3 subtract 10x from each side
10x-10x=0
10x-10x=0
we're left with 8 = 6
8 is not equal to 6 meaning that there are no solutions to the equation

Please help find the volume by using 3.14 as pi
Answer:
P
v = 794.0275 in³
Q
v = 1,307.81 in³
Step-by-step explanation:
volume of cone
v = πr²h
----------------------------
cylinder P
v = 3.14 * (4.25²) * 14
v = 794.0275 in³
-----------------------------
cylinder Q
v = 3.14 * (7²) * 8.5
v = 1,307.81 in³
.. The solution of which quadratic Inequality is shown on the number line?
O (3+6) (3 – 4) <0
O (2-6) (2 - 4) > 0
O (30 – 6)(+4) <0.
O (30 – 6) (x – 4) <0
Explanation:
If you graphed (x-6)(x+4) on the xy plane, then you'll see a parabola forming. This parabola has roots at x = -4 and x = 6. Between these roots, the curve is below the x axis. This visually shows that (x-6)(x+4) is negative when -4 < x < 6.
Furthermore, we can say that (x-6)(x+4) is negative or zero when [tex]-4 \le x \le 6[/tex] which corresponds directly to the number line graph your teacher gave you. The endpoints being closed circles mean "include this as part of the shaded solution set".
