What is the value of the smaller zero of the function defined by 2x2 + 9x + 7?
Answer:
We can factor the quadratic function into (2x + 7)(x + 1) and this way, the terms sum to 2x^2 + 9x + 7. Looking at the 2 factors 2x+7 and x+1, the way to find the zeros is to set both of these expressions equal to 0. Therefore we have: 2x+7=0

Roy has $30 in a savings account. The interest rate is 10% per year and is not
compounded. How much will he have in 4 years?
Answer:
$43.92
Step-by-step explanation:
1st year:
30 x 10% = 3
30 + 3 = 33
2nd year:
33 x 10% = 3.3
33 + 3.3 = 36.3
3rd year:
36.3 x 10% = 3.63
36.3 + 3.63 = 39.93
4th year:
39.93 x 10% = 3.99
39.93 + 3.99 = 43.92

find the value of x and show how
Answer:
x≈ 5.4
Step-by-step explanation:
180°-110°= 70°
70° is the measure of the angle represented by 11x+11
set the equation equal to 70°
11x+11= 70°
-11 on both sides
11x= 59
÷11 on both sides
x≈ 5.4
11(5.4)+11≈ 70.4 ≈70
write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14, 6)
Answer:
y=-5/8x-11/4
Step-by-step explanation:
y-y1=m(x-x1)
y-6=-5/8(x-(-14))
y-6=-5/8(x+14)
y=-5/8x-70/8+6
y=-5/8x-11/4
The first three terms of an arithmetic sequence are as follows. 17,25 , 33 Find the next two terms of this sequence.
Answer:
the next two terms are 41 and 49
Answer
41, 49
Step-by-step explanation.
17 too 25 is 8 and from 25 too 33 is also 8 so the 4th term is 33+8= 41 and the 5th term is 41+8=49

find the slope of the line that goes through (-4,2) and (3,-5)
Answer:
-1
Step-by-step explanation:
m = -7 / 7 = -1 / 1 = -1
Answer:
-1
Step-by-step explanation:
To find the slope given two points, use the formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the formula would be: [tex]\frac{-5-2}{3-(-4)}[/tex]. Solve the top first: -7. Solve the bottom next: 7. So your answer is: [tex]\frac{-7}{7}[/tex] or -1.

The shapes of the horizontal cross-sections of the cone below are not all
congruent.
A. True
B. False
Answer:
B. False
Step-by-step explanation:
We are given the statement,
'The shapes of the horizontal cross-sections of the cone are all congruent'.
Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.
Further, the radius of the circle vary depending on the position form where the cone is cut i.e.
If cut from the top, the circle is approximately equal to a point.
If cut from the middle, the radius of the circle is less than the radius of the cone.
If cut from the bottom, the radius of the circle is equal to the radius of the cone.
Now, 'two figures are congruent if they overlap each other'.
Since, the circles have different radius, they will not overlap each other.
Thus, all the cross-sections of the cone would not be congruent.
Hence, the given statement is false.
Step-by-step explanation:
The solution is, the given statement is B. False.
What is a cross-section of any shape?A cross-section is a shape formed by cutting a solid (such as a cone, cylinder, or sphere) with a plane. If a cylinder-shaped object is cut by a plane parallel to its base, the resulting cross-section is a circle. As a result, the object intersected.
here, we have,

find lowest common denominator write the equivalent fractions 2/5 and 1/10
Answer: 4/10 = look below for explanation
Step-by-step explanation:
Transform 2/5 into the same demononator
= 2/5 becomes 4/10 because you've multiplied 2x2 and 5x2
which becomes 4/10 and 1/10
to solve: 4/10 - 1/10 = 3/10
