Answer:
B. (b x d) - c
Step-by-step explanation:
i. -(a x d) + b
= -(6 x 
) + 8
= -3 + 8
= 5
ii. (b x d) - c
(8 x ) - 4
= 4 - 4
= 0
iii. 2(b x f) + a
= 2(8 x 
) + 6
= 4 + 6
= 10
iv. (a x e) - c
= (6 x 
) - 4
= 2 - 4
= -2
Thus, the expression which is equivalent to 0 is that of option B.
Let a,b and c is side of a triangle where:
a = 1
b = 5
c = 11
a^2 + b^2 = c^2. if the following statement is right, then triangle have these side.
1^2 + 5^2 = 11^2
1 + 25 = 121
26 != 121 ( != means not equal to)
Therefore, triangle can't have side length of 1, 5 and 11 ft.
Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm
There is no sufficient evidence to suggest that men and women have equal success in challenging calls. This was illustrated in the hypothesis.
<h3>How to compute the value?</h3>
It should be noted that based on the information given, P1 will be:
= 424/1436
= 0.295
P2 will be:
= 222/754
= 0.294
The value of the test statistic will be:
= (424 + 222)/(1436 + 754)
= 646/2190
= 0.2949
In this case, the value of the test statistic falls on the rejection region, therefore, there is no sufficient evidence to suggest that men and women have equal success in challenging calls.

Answer:
Height after 5 seconds is <em>215 ft</em>
Step-by-step explanation:
Given that:
The initial velocity of object which is projected upwards is 123 ft/sec.
Height of the object, <em>h</em> after time <em>t </em> in seconds, is given as:
Here, <em>t </em>will always be positive, so 
and 
will also be positive.
But coefficient of is negative, that means something is subtracted from the positive term .
To find:
Height of object after 5 seconds.
Solution:
Given that 
seconds.
Let us put the value in the given relation of 
and 
:
So, height after 5 seconds is <em>215 ft</em>.
