The function h defined by h(t)=(-4.9t + 29.4)(t+2) models the height in meters, of an object t seconds after it is launched. When will the object hit the ground?
Answer:
The time the object will hit the ground is 2 s.
Step-by-step explanation:
Given;
h(t) = (-4.9t + 29.4)(t + 2)
Open the bracket;
h(t) = -4.9t² + 29.4t -9.8t + 58.8
h(t) = -4.9t² + 19.6t + 58.8
When the object hit the ground, the final velocity will be zero;
[tex]v = \frac{dh}{dt} = 0 \\\\\frac{dh}{dt} = -9.8t + 19.6 = 0\\\\9.8t = 19.6\\\\t = \frac{19.6}{9.8} \\\\t = 2 \ s[/tex]
Therefore, the time the object will hit the ground is 2 s.

-7 = 2x - 7
A. 0
B. 4
C. Infinite Solutions
D. No solutions
Answer:
A
Step-by-step explanation:
the variable is how many times the two will be multiplied, so 2 times 0 equals 0, there by making the problem. -7= - 7
Answer:
that will be A. 0
Step-by-step explanation:
first, i flip the equation
2x - 7= -7
next, i add both side by 7
2x−7+7=−7+7
2x=0
and finally, you divided by 2
2x/2 = 0/2
you get x = 0
Find the value of k and x2
x^2+ 13x + k = 0, x1=-9
Given:
The quadratic equation is:
[tex]x^2+13x+k=0[/tex]
[tex]x_1=-9[/tex]
To find:
The value of k and [tex]x_1[/tex].
Solution:
We have,
[tex]x^2+13x+k=0[/tex] ...(i)
Putting [tex]x=-9[/tex], we get
[tex](-9)^2+13(-9)+k=0[/tex]
[tex]81-117+k=0[/tex]
[tex]-36+k=0[/tex]
[tex]k=36[/tex]
Putting [tex]k=36[/tex] in (i), we get
[tex]x^2+13x+36=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x+4x+36=0[/tex]
[tex]x(x+9)+4(x+9)=0[/tex]
[tex](x+9)(x+4)=0[/tex]
[tex]x=-9,-4[/tex]
Here, [tex]x_1=-9[/tex] and [tex]x_2=-4[/tex].
Therefore, the required values are [tex]k=36[/tex] and [tex]x_2=-4[/tex].
Question 7: The red line has an equation of y = -1/2 x + 2. The blue line is perpendicular to the red line. Write the equation for the blue line. EXPLAIN PLS
Answer:y=2+2x
Step-by-step explanation:
Perpendicular means the slope is the opposite reciprocal of the red line’s. Opposite reciprocal means that if the red line has a negative slope the blue line will have a positive one, and you flip the fraction of the red line from 1/2 to 2. The y intercept is at 2 so that’s why there is a +2

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Find the equation of the line pls helppppppp
Answer:
y=2x+4
Step-by-step explanation:
y=2x+4
Answer:
y = 2x + 4
Step-by-step explanation:
The formula for the equation of a line is y = mx + b, where m is the slope and b is the y-intercept. The y-intercept is where the line passes through the y-axis, which would be (0,4), which is positive. To find the slope, find where the line passes through a point, and then count how many units there are till the next point. For this example, you could start from the y-intercept, (0, 4) and to get to the next point, you will go up 2 units, and the right 1 unit. This means that the slope is 2/1 (because it's rise over run) which is the same as 2. So just plug it into the equation, and you get y = 2x + 4.

2. The value of x is:
90°- 38° = 52°
Answer:
Step-by-step explanation:
180 = 40 + x + 30
110 = x
90 = 38 + x
52 = x

I need help with this please help me.
Answer:
a) $93, $117.80, $86.80, $68.20
b) $365.80
Step-by-step explanation:
a)
Add 12 hours to each p.m. time to make the subtraction of hours easier.
Also, use decimal numbers to do the subtraction. Remember that 0:30 means 30 minutes which is 0.5 hour, so 7:30 is the same as 7.5 as a decimal.
Monday: 8:00 to 15:30
15:30 - 8:00 = 1.5 - 8 = 7.5 hours
7.5 hours * $12.40/h = $93
Wednesday: 7:30 to 17:00
17:00 - 7:30 = 17 - 7.5 = 9.5 hours
9.5 hours * $12.40/h = $117.80
Friday: 9:00 to 16:00
16:00 - 9:00 = 16 - 9 = 7 hours
7 hours * $12.40/h = $86.80
Saturday: 10:30 to 16:00
16:00 - 10:30 = 16 - 10.5 = 5.5 hours
5.5 hours * $12.40/h = $68.20
b) Add all the daily amounts above.
$93 + $117.80 + $86.80 + $68.20 = $365.80

Find the surface area of the prism. Whoever solves this will guarantee get Brainliest Answer!!!
To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.
