Answer:
(-6, -5).
Step-by-step explanation:
If there is a zero between the integers there will be a change of sign of f(x).
x^3 + 5x^2 - x - 6
f(1) = 1 + 5 - 1 - 6 = -1
f(-1) = -1 + 5 + 1 - 6 = -1
f(2) = 8 + 20 - 2 -6 = 20
There' a change of sign between f(1) and f(2) so there is a zero between (1, 2).
f(-2) = -8 + 20 + 2 - 6= 6
So there is also a zero between -1 and -2. (-2, -1)
F(-4) = 14, f(-5) = -1 = change of sign so there is also a zero in (-5,-4)
f(-6) = -36 - no change in sign between -5 and -6.

Find the center and radius of the circle
A bag contains 2 red, 5 blue, and 7 yellow marbles. Find the probability of drawing a yellow or a red.
Answer:
drawing a red marble would be 2 in a 14 or 1/7 chance n drawing a yellow would be 1/2.
The probability of drawing a yellow marbles is 1/2
What is probability ?Probability means the quality or state of being probable; the extent to which something is likely to happen or be the case
We have,
Bag contains marbles
Red=2
Blue=5
Yellow=7
Total marbles in bag = 2+5+7=14
The total number of ways of selecting one marble out n(s) = 14[tex]C_{1}[/tex]
= 14 ways
Let E be the event of selecting yellow marbles
Since, the bag contains 7 yellow marbles
one yellow marble can be draw from 7 yellow n(E) =7[tex]C_{1}[/tex]
= 7 ways
We know the formula,
P(E)= n(E)/n(s)
= 7/14
= 1/2
Hence, the probability of drawing a yellow marbles is 1/2

Math problem: There are 36 carpenters in a crew. On a certain day, 29 were present. What percent showed up for work? (round to the nearest tenth)
Answer:
10%
Step-by-step explanation:
Answer:
The percentage showed up for work is 8.556 %
● Given that total number of Carpenters is 36.
● On a certain day only 29 carpenters were present.
● To calculate the percentage we have to divide the number of carpenters present on that specific day by the total number of carpenters and multiply the product with 100 i.e., we have to divide 29 with 36 and multiply it with 100.
Percentage = (29 / 36) * 100
= (0.80556) * 100
= 80.556
● Therefore the required percentage is 80.556%

Please Answer !! A store is having a sale on almonds and jelly beans. For 5 pounds of almonds and 3 pounds of jelly beans, the total cost is $23. For 2 pounds of almonds and 6 pounds of jelly beans, the total cost is $20. Find the cost for each pound of almonds and each pound of jelly beans.
Answer:Let x = number of pounds of jelly beans
y = number of pounds of almonds.
Then, 4x + 8y = 33
2x + 3y = 13
Multiply the second equation by -2 to get the system:
4x + 8y = 33
-4x - 6y = -26
Adding the equations, we get 2y = 7. So, y = 3.5
Substitute for y in either of the given equations: 2x + 3(3.5) = 13
2x + 10.5 = 13
2x = 2.5
x = 1.25

In 2010 Harry bought 200 shares in ford motors company stock for 35.21 per share in 2018 he sold the shares for 26.78 each express his capital loss as a percent
Answer:
23.94%
Step-by-step explanation:
In 2010, Harry bought 200 shares in ford motors company stock for $35.21 per share. This means that the cost price of buying the 200 shares is:
C = 200 * 35.21 = $7042
In 2018, he sold the shares for $26.78 per share. The selling price of 200 shares is:
S = 200 * 26.78 = $5356
The loss is given as the cost price minus selling price. That is:
L = CP - SP
L = 7042 - 5356
L = $1686
Percentage loss is given as loss divided by cost price multiplied by 100:
%L = 1686 / 7042 * 100
%L = 23.94%

What is the lateral surface area of this triangular prism in square centimeters?
Answer:
lateral surface area of the triangular prism = 128 cm²
Step-by-step explanation:
The question is incomplete the picture below represents the complete question.
Lateral surface area of a triangular prism = PH
where
p = perimeter of the triangle
H = height of the prism
perimeter = 5 + 5 + 6 = 16 cm
height of the prism = 8 cm
Lateral surface area of a triangular prism = Perimeter of the triangle × height of the prism
lateral surface area of the triangular prism = 16 × 8
lateral surface area of the triangular prism = 128 cm²

A skate board was originally priced at £100 on Thursday.
On Friday the price was reduced by 50%. On Saturday, Friday's price was reduced by a further 30%. On Sunday, Saturday's price was reduced by a final 10%.
What was the final percentage reduction on the original price?
Answer:
31.5
Step-by-step explanation:
50 percent of 100 would be 50, so you subtract 50 from 100, and 30 percent of 50 is 15, so you subtract 15 from 50 and then get 35, which 10 percent of is 3.5, and finally you subtract 3.5 from 35 and you end up with 31.5.

In ΔTUV, t = 410 cm, ∠U=27° and ∠V=78°. Find the length of v, to the nearest 10th of a centimeter.
Answer:
[tex]v \approx 415.2\,cm[/tex]
Step-by-step explanation:
The angle T is:
[tex]\angle T = 180^{\circ} - 27^{\circ} - 78^{\circ}[/tex]
[tex]\angle T = 75^{\circ}[/tex]
Now, the length of v is determine by the Law of Sines:
[tex]\frac{410\,cm}{\sin 75^{\circ}} = \frac{v}{\sin 78^{\circ}}[/tex]
[tex]v = (410\,cm)\cdot \left(\frac{\sin 78^{\circ}}{\sin 75^{\circ}} \right)[/tex]
[tex]v \approx 415.2\,cm[/tex]

Two angles are supplementary. If the m∠A is five times the sum of the m∠B plus 7.2°, what is m∠B?
Answer:
m∠B = 24°
Step-by-step explanation:
m∠A + m∠B = 180°
m∠A = 5 ( m∠B + 7.2 )
5 ( m∠B +7.2 ) + m∠B = 180
5m∠B + 36 + m∠B = 180
6m∠B = 180 - 36
6m∠B = 144
m∠B = 24°
